6. Wipers

The guideways o aluminum roller guides are equipped with wipers

to protect against coarse environmental contamination

7. Slide resistance / adjustment

Follow the steps on how to adjust GDL cassettes to the rail

The new GDL catalog has many changes due to an expanded

product line The change to eature descriptive part numbering

was done to accommodate all current and uture oerings o the

GDL product The goal is to have standard eatures and options

available, or a perect t into your application

Included in the chart below are hex sizes, drag resistance and

torque ratings or adjusting the cassette

71 GDL adjustment procedure

Do not measure sliding resistance with wipers on.

1) Lay the rail out on the fat surace with the datumline acing

away rom you Anchor the rail to keep it rom shiting when sliding

resistance is applied to the cassette

The datum line is a reerence groove on one side o the rail.

2) Set the roller cassette on the rail with the adjustment screwacing towards you, while the datum line on the rail is away romyou Do not install the wipers on the cassette yet

Do not install the wipers yet.

3) Make sure the our bolts on the adjustable side o the cassetteare slightly loose and the bolts on the xed side are tight beoreadjuting the drag screw

One side o the cassette is xed and the other side is foating.

4) The drag hex screw is located on one side o the cassetteAdjust the screw in or more drag and out or less Do not try toadjust cassette with top plates bolts tight

See the chart or drag adjustment hex screw size.

GDL Aluminum Roller GuidesTechnical inormation

1. Features o the guide system

Aluminum roller guides consist o a double sided rail and a roller

cassette or two single sided rails and two roller shoes Aluminum

roller guide rails and cassettes are made o aluminum alloy The

rollers are very smooth running on precision polished guideways

made o high alloy spring steel The special cross pattern

orientation o the running rollers provides high load and moment

capacity in all directions

Their special eatures are: light weight, small dimensions, and

high speed o displacement Aluminum roller guides are

economical and universal handling components, which are

mostly or all corrosion-resistant and available at a avorable price

2. Size o the guide system

To select the right guide size, rst the moments and orces acting

on the bearing have to be determined

Recommended saety actors (with ISO screws quality 88):

Thrust load S > 13

Tensile load S > 40

Moment load S > 60

3. Material

The basic body o GDL aluminum roller guides is made o

aluminum alloy The giudeways consist o hardened, high alloy

spring steel or o stainless steel By using basic bodies o

aluminum, the moved masses are reduced which allows light-

weight construction requiring lower moving orces and reducedenergy consumption Still the integrated GDL system sustains

high load and moment ratings

4. Operating temperature

GDL linear guides can be operated within a temperature range

rom -10 C up to + 80 C For other temperatures, please consult

actory

5. Screwed connections

GDL linear gudies are ixed to the mating structure by the

mounting holes in the rails and the cassettes ISO screw quality88 should be used with DIN 433 washers

To secure the screwed connections, we recommend that suitable

locking means be utilized as necessary

73 Double sided rail and roller cassette

To change the clearance setting, rst the slave adjustable shoescrews on the cassette top plate are slightly loosened Ater

wards, the drag adjustment set screw is turned to increase o

decrease slide resistance o the cassette Turning the drag

adjustment set screw eects a displacement o the roller shoe in

relation to the cassette top plate

Ater re-tightening o the cassette top plate, the sli de resistance

can be checked This procedure can be repeated until the desired

slide resistance is achieved

74 Rails and rollershoes

When installing, it is important to distinguish between the maste

xed side and the slave adjustable side rollershoe and rail The

rail on the master xed side is aligned to the mating structure and

astened securely by all screws

The rail on the slave adjustable side should be lighly tightened

and movable with light orce during initial alignment o paralle

rails Guage blocks should be used between the parallel rails, by

locating o the aligned and mounted master rail, in order to align

the slave rail parallel to the master rail Slave rail mounting bolts

should be tightened as the slave rail is aligned at each bol

position See paragraph 113 or urther instructions on mounting

parallel single sided rails

75 Centering groove on the master xed shoe and custom top plate

Each pair o rollershoes are provided with centering grooves o

optimum alignment to their mating top plate during mounting

One rollershoe should be designated as the master ixed

rollershoe, even though both are designed with a centering

groove on their top surace The other shoe will serve as the

slave adjustable side rolelrshoe The mating customized top plate

should be machined with a centering shoulder according to the

ollowing data

5) Adjust the drag on the cassette by sliding as it slides downthe rail Feel or an even amount o resistance as you turn thehex screw in and out

6) Tighten down the top plate bolts to the proper torquespecication The tightening o the top plate bolts will add someresistance I necessary, the adjustment procedure can berepeated or better sliding resistance or your application

See the chart or top plate hex size and torque rating.

7) I the adjustment is done without a scale, it should moveevenly Some examples o improper adjustment are: I thecassette hops, it is too tight I it is too loose, the top plate othe cassette will have play Try to be in the middle

8) To check your settings use a pull or push style scale Slidethe cassette down the entire rail at an even speed, measuringthe drag resistance Your hightest drag rating should bereerenced when looking at the chart

See the chart or drag resistance ratings or the size and type ocassette.

9) Install the clip on wipers The wipers will add between 1-3

ounces o resistance The wipers do not add any additional rollerpreload to the rail

The clip on wipers can be installed at this time.

72 Double sided rail and cassette

Aluminum roller guides are adjusted in such a way that therequired stiness under load is obtained I sel adjustment ispreerred, we recommend that you measure the slide resistanceas shown below Beore doing so, the mating structure should bechecked or dimensional accuracy and fatness

The cassettes which are mounted on the rails are adjusted

clearance-ree, without play This adjusting method is required at

the point on the rail where the cassette travels with the least slide

resistance Adjustment is completed in the non-loaded condition

The tolerances below reer to this condition

Tolerances in the guide system may cause slight variations in

the slide resistance, when the adjusted cassette is moved along

the guide rail

76 Adjusting cassette built with rollershoes and custom top plate

The centering shoulder on the top plate should be assembled

with its respective xed rollershoe centering groove and securely

torqued to recommended specication See cassette screw

torque specications under step 5, on page 10

Assemble the adjustable rollershoe to the top plate also, parallel

to the xed rollershoe on the same side o the top plate Its

asteners should be lightly tightened so that the adjustable

rollershoe can be moved with light nger presssure

As assembled cassette can then be slid onto parallel rails, while

keeping the xed rollershoe on the master xed rail side The

incorporated drag adjustment set screw can then be turned

clockwise to remove cassette play, or counter clockwise to reduce

slide resistance while maintaining zero play

Once the desired slide resistance is achieved with no cassette

play, the adjustable rollershoe asteners can also be torqued to

specication

8. Running accuracy

The running accuracy is measured rom the top plate surace o

the cassette, to the ideal straight line o travel Running accuracy

o the cassette to the rail is +/- 03mm (0012) per meter, granted

no greater than (0024) straightness deviation per meter is

maintained when mounting the rail

9. Contact and support suraces

The contact and support suraces have a substantial infuence

on unctioning and precision o linear guides Depending on the

unctional requirements o the system, the mating structure has

to be machined with the corresponding degree o precision

Machining errors on the mating structure will otherwise add to

the running error o the guide system In order to assure troublereeunctioning, we recommend that a max straightness deviation o

01 mm (0039) per running meter be maintained when

mounting the rail

10. Design hints

101 Parallel double sided rails and cassettes

The master xed rail should always be established straight and

true rst, within the maximum straightness deviation specied in

paragraph 9 With parallel rail arrangements, both rails should be

mounted on the same mounting surace elevation and treated

with equal surace preparation and tolerancing practices Precise

alignment in terms o spacing, parallelism and height is very

important

When coupled parallel to a driving actuator system, the adjustable

side o the cassette should be placed on the side closest to the

driving actuator This will minimize driving actuator torquetranserred to the adjustable side o the cassette

11. Guide mounting instructions

The useable load capacity is inluenced by the connection

between the guide elements and the mating structure For this

reason, a fat, straight and solid secure mounting surace should

be provided Adequate support o qualied loads and moments

can then be achieved, along with desired running accuracy

111 Mounting double sided rails and cassette

Depending on the load situation, certain double sided rails shouldeither be screwed or screwed and dowelled, and respectivelyput into grooves or against a shoulder

The rails can be secured best against shoulders and are screwedor screwed and dowelled to the mating structure Ater naladjustment o rail straightness and parallelism, the rail mountingscrews are tightened starting in the middle o the rail length Railmounting bolts should be torqued to specication by alternatingbetween each bolt The installer should start with the bolt in thecenter o the rail length and proceed by alternating between eachbolt let o center and each bolt right o center, while workingtowards both ends o the rail

Aterwards, the cassette should be moved back and orth alongthe total stroke distance o the rail I the cassette travelssmoothly, the mounting process can proceed or be completed

112 Mounting parallel double sided rails and cassettes

With parallel double sided rail arrangements, we recommend thatthe master xed rail side and slave adjustment rail sides o theguide system be identied This allows optimum tolerances inparallelism to be achieved best by adjusting the slave adjustablerail, parallel to the master rail The master xed rail side should bemounted rst to achieve the initial line o straight travel

The example below displays a convenient method or adjustingthe slave adjustable rail parallel to the xed master rail Oncethe cassette travel is smooth, without play, one can proceedwith rail mounting

Note that the top plate spanning across the cassettes on opposite

rails is completely bolted down to the cassette on the masterxed side only The top plate end over the slave adjustable side

is only bolted in one location, in the center o the slave adjustment

side cassette With one bolt holding the top plate to the slave

adjustment side cassette, this cassette can pivot while the slave

adjustable rail sel-aligns parallel to the xed master rail side

The foating top plate setup is stroked along the entire rail length,

to establish the parallelism between the two rails

Calibrated guage blocks can also be used to establish equal

integrity in rail parallelism The installer should seat and

temporarily clamp short pieces o precision ground round stock,

tangent to the two guideways on the inside o each rail

The calibrated guage blocks can then be used, to locate o the

precision round stock on the master xed rail, in order to set the

slave adjustable rail parallel The guage blocks are then locating

the same way that the foating top plate is, by reerencing both

the master and slave rail guideway suraces to establish

parallelism

Once the slave adjustable rail has been sel-aligned, its bolts

should also be torqued to specication in the order mentioned in

paragraph 111 The top spanning across both cassettes on

opposite rails, can then be securely astened using all cassette

mounting bolt holes

12. Keyed butt-jointing o rail sections

121 Rail hole spacing

Butt-jointed rails over L = 4000 mm are sectioned togethe

according to the GDL standard See GDLs Keyed Butt-Jointed

Rail Option on page 8 Butt-jointed rails sections are cut so tha

the standard rail mounting hole spacing is maintained across al

butt-joints

Keyed butt-jointed rails are usually shipped completely

assembled, but sometimes must be shipped partially assembled

due to shipping length limitations and shipping care Partially

assembled butt-jointed rails are supplied with a butt-jointing

clamping xture and the keyways and screws or astening rai

section together

122 Mounting o butt-jointed rails

Clean mounting suraces, then place rail sections loose on the

guide path, one behind the other Lay the rails in their correc

sequence o the system design (ie: 1, 2, 3, 4etc) The

orientation o the depth groove on the lower surace o the rai

should always be on the same side or all rail sections being

butt-jointed

Any non-assembled rail sections should be aligned with the

actory supplied butt-joint clamping xture as displayed below

See explanation o GDLs Keyed Butt-Jointed Rail Option on

page 8

Once all rail sections are assembled, the complete guide path

can be aligned and astened Alignment and astening should

be conducted according to the applicable guide arrangemen

and steps previously described in this technical inormation
