Rexroth Precision Ball Screw AssembliesProduct Overview

Double nut machine tool line forFLM-E-B

The location of the double nut halvesby means of radial set screws isinnovatory. A conscious decision wasmade here to omit the usual additio-nal intermediate washers foradjusting the preload. Innovativeproduction technology makes thispossible.

Depending on the application, we willpreload the nut system to 7% or 10% ofthe basic dynamic load rating. Maximumrigidity values are reached.

Rexroth precision ball screwassemblies for machine tools

The starting point for this product line wasthe demand for ball screw assemblies withthe highest possible load rating andrigidity with, at the same time, high linearspeeds.

The ball raceway in the nut and screw wasoptimized for maximum rated load withrespect to ball diameter and racewaygeometry. Recirculating elements withtangential removal of the balls guaranteevery quiet running (even at the highestpossible linear speeds) and a constanttorque at low speeds.

At the same time, supplementing our maincatalog R310EN 3301 (2004.06), designsuggestions were incorporated for screwfixed bearings which ensure maximumload rating and rigidity. The design of thepin diameter and the axial locating face forthe bearing respectively have beenoptimized by means of friction welding,contact rings or a ball raceway which isnot ‘drilled through’.

The product line is rounded off by thelarge pillow blocks for screws larger than50 mm diameter.

R310EN 3302 (2004.06)7


Single nut machine tool series forFFM-E-B

With this single-nut flange, shiftingbetween two independent ballcircuits eliminates backlash with 2-point contact of the balls andspecified rigidity is achieved.

Accordingly, the screw has two ballraceways in the relevant version with leadsabove 20 mm.

Alternatively, preload can be achieved bymeans of ball sorting with 4-point contact.We will preload the nut system to 2% or5% of dynamic load capacity to suit theapplication and requirements.

Inquiries and ordersAll nuts, screws and end machining detailscan now be defined with the order code.

We have taken account of all formerselection criteria as well as adding newones. The diversity of possiblecombinations is limitless.

Attention is focused in particular on thedefinition of end machining details. Formany design versions there is a prepareddefinition, providing you with a suitablesolution for practically every application.

If you wish to send us an inquiry, simplycomplete the form on Page 47 of thiscatalog.

If no drawing is available yet, pleasespecify your wishes using the variableorder code. You will find a summary of theoptions on Page 15. You will find furthersuggestions in catalog R310EN 3301(2004.06).

Should you already have a drawingavailable as a CAD file (in Pro/E20,AutoCAD/Genius 14, AutoCAD 2002 orDXF formats), you can send us the data bye-mail (see the back cover of the catalogfor our e-mail address).

If the drawing exists on paper only, youcan of course send it to us by conventionalmail.

Each customer-specific precision ball screwassembly is issued with an ID numberwhen an order is placed. If you have anysubsequent queries, you need only quotethis ID number.

Screws with double nuts for FLM-E-B

Single nut machine tool series forFFM-E-B

The single nuts in this line are providedwith two independent ball circuits. Thepreload of these nuts can be achieved byball sorting in the 4-point contact or byshifting between the 2-point contact ballcircuits.

Depending on the application, we willpreload the nut system. Details availableon request.

Grease lubricationThe advantage of grease lubrication isthat the ball screw can run long distanceson one supply of grease. As a result, alubricating system is not required in manycases. The amount of grease used shouldfill the nuts to approximately half of theircapacity.

All commercially available ball bearinglubricating greases may be used.Read the lubricant manufacturer’sspecifications carefully! Never use greaseswith solid lubricant components (e.g.graphite or MoS2).

Oil lubricationThe influence of the temperature on theperformance of the ball screw is verysignificant, as the thermal expansion ofthe ball screw interferes with thepositioning accuracy of the assembly.

One of the advantages of oil lubricationover grease lubrication is therefore theminimized heat build-up of the ball screw,particularly at high speeds.

As a rule, commercially available mineralbase oils used for ball bearings aresuitable. The necessary viscosity dependson the speed, temperature and loadconditions of the respective application(see DIN 51501, 51517, 51519 and GfTWorksheet 3).

Oils ranging from ISO VG 68 to approx.ISO VG 460 are used in practice. The highviscosity grades (e.g. ISO VG 460) shouldbe preferred in general and particularly forslow running screws. A maximumrelubrication interval of up to 10 operatinghours can be attained with smallquantities from the table along side.

Relubrication quantity, seetable for NLGI 2 greases.


Standard lubrication practices for ballbearings also apply to ball screws.Lubricant loss is, however, greater thanthat e.g. from conventional ball bearingsdue to the axial motion between the screwand the nut.

Marginal conditions:Load = 0.2 Cnmin = 100 rpmTempmax. nut = 80 °CTempperm. nut = 60 °C

Greases in accordance with DIN 51825K2K and, for higher loads, KP2K of NLGIClass 2 in accordance with DIN 51818 arerecommended for the longest possiblelubrication intervals. Tests have shownthat greases of NLGI Class 00 achieve onlyabout 50% of the running performance ofClass 2 at higher loads.The lubrication interval depends on manyfactors such as the degree ofcontamination, operating temperature,load, etc. The following values can thusserve only as a guideline.
