Spring Clip Connecting Link Spring clip connecting links come packaged with slip-fit cover linkplates. The cover link-plate is held in place by a spring clip, split at one end to permit easy installation and removal. This style of connecting link is standard for up to ANSI 50 chains. Press-fit cover linkplates are also available and are recommended for heavy duty applications.
Bushed Center LinkplateConnecting Link (BCL)This connecting link is standard for all press-fit multiple strand chains of ANSI 50 and larger. The bushings are press fit in the centerplate pitch holes and slip-fit on the pins. The BCL cover linkplate is press fit on the pins.
Roller LinkStandard for all sizes of roller chain, these links are furnished as complete assemblies. The bushings are press fit into each of the linkplates.
Four-Pitch Press-fitOffset Link AssemblyFor Multiple Strand Chain OnlyThe pins of this assembly are press fit into the offset links. A four-pitch length permits the use of BCL connecting links on either end, giving maximum capacity to the chain assembly.
CHAIN COMPONENTS
Riveted Connecting LinkRiveted connecting links are available for all roller chain sizes. This connecting link is press-fit on the pins. Pins should be riveted or peened on the ends once the cover linkplate is in place.
Cottered Connecting LinkThis connecting link is available in either a press-fit or slip-fit construction and is stan-dard on ANSI 60 and larger. Press-fit connect-ing links are recommended for heavy duty applications and press-fit cover linkplates are standard on multiple strand oil field chain.
Two-Pitch Offset LinkFor Single Strand Chain OnlyThis link is available for all sizes of single strand chain and consists of an offset link and roller link assembled together. This link’s pin is press fit in the offset linkplates and is riv-eted for a secure fit. The press-fit construction of this assembly greatly increases its structur-al rigidity, reliability, and durability. For these reasons, the two-pitch offset assembly is rec-ommended over a single-pitch offset link.
Single-Pitch Offset LinkThis link is packaged unassembled with one slip-fit pin. One end of the connecting pin is milled flat to prevent the pin from turning in the linkplate.
These tests were performed by Diamond Chain using protocols and methodology that were reviewed, verified, and approved by an independent third party.
Spring clips should be installed with the closed (solid) end toward the direction of chain travel.Did You Know?
When selecting roller chain for a drive system, it is important to understand the difference between tensile strength and working load. Tensile strength is a measurement of the static load required to break a chain while working load is the amount of force exerted on a chain by a drive system. Roller chains with equal tensile strengths can have significantly different working loads as there is no consistent relationship between these two measurements. Tensile strength should not be used as a indication of a chain’s quality or as a substitute for allowable working load. Calculating Allowable Working Load Allowable working load can be calculated using one of the following equations. Note that the load or tension applied to a chain in service should never exceed 1/6th of the minimum ultimate tensile strength. A chain that is loaded above 50% of the MUTS value will be permanently damaged after only one cycle.
Additional Terminology: • Average ultimate tensile strength is the load required for a sample of chains to break. • Minimum ultimate tensile strength, or MUTS, is the static load required for a single chain to break. • Ultimate tensile strength is the maximum load a single chain will withstand before breaking.
When ordering roller chain, include information on chain size, length of chain or number of pitches, and construction style – riveted or cottered. For multiple strand chain, the construction must be specified – press-fit or slip-fit construction. When ordering attachment chain, attachment and attachment spacing must be specified.
NOTE: All chains are furnished with connecting links unassembled unless otherwise specified.The following are examples of configurations in which chains can be supplied.
ORDERING ROLLER CHAIN
The left-hand digit in the two-digit part number denotes the number of 1/8“ segments in the pitch. For example, ANSI 80 chain would be 8 segments of 1/8” for a total of 1”.
Did You Know?
If a specific length of chain is not required, order a stock length. Stan-dard lengths are 10 feet, 50 feet, and 100 feet. One extra connecting link is furnished with every 5 feet of ANSI 25 through 50 riveted chain.
For a specific length of chain, the length should be given in number of pitches. The connecting link should be included in this number.
When an odd number of pitches are required for an endless length, in-dicate whether a single-pitch offset or two-pitch offset link is needed.
When chain requires two connecting links to attach the ends to other pieces of equipment, the chain should be ordered as “x” number of pitches including connecting link each end.
If the chain does not require connecting links, it may be specified as “x” pitches long roller link each end. Odd number pitch lengths are preferable, even number pitch lengths will require an offset link.
Chain may be ordered as “x” pitches endless. Indicate whether they are to be riveted endless (permanent connection), or connected with a connecting link (detachable).
Chain length should always be the complete length, including any connecting or offset links required. If anything other than a connect-ing link is required, please specify.

CHAIN ASSEMBLY AND DISASSEMBLY TOOLS
Connecting Tools
Pin Extractor Tools
CT35
Connecting Tool - Small
For use with ANSI 35 through 60H roller chain.
CT80
Connecting Tool - Large
For use with ANSI 80 through 240 single strand chain and most conveyor and engineered chains with a width of 5/8” or wider between the inside links. For multi-strand chains, a second connecting tool will aid in the alignment of the chain.
CT80-Cable
Cable Connecting Tool - Large
For use with ANSI 80 through 240 single strand, multi-strand and double-pitch chain, and most conveyor and engi-neered chains with a width of 5/8” or wider between the inside links.
PE113
Pin Extractor - Small
For use with ANSI 25 through 60H roller chain.
PE135
Pin Extractor - Large
For use with ANSI 80 through 100H roller chain.
PERE157
Pin Extractor - Extra Large
For use with ANSI 120 through 160 roller chain.
Connecting ToolsCT35 & CT80
Hook the two arms of the connecting tool onto each end of the chain. Turn the screw clockwise to bring the two ends of chain towards each other. Insert the connecting link and complete assembly. Note: This tool is not made to stretch chain but to hold chain in place for assembly.
CT80-CABLE
Place the hooks of the connecting tool on the rollers past the link or links to be removed or replaced. The slack in the cable should be taken up with a wrench until the chain between the hooks is relieved of tension. This will allow for the removal of the link with a roller chain pin extractor. A new master or replacement link can then be inserted. The cable can then be released with the lock lever and the tool can be removed.
Pin ExtractorsPE113, PE135 & PERE157
It is recommended that the “side-mashed” or “spun” pin heads be ground flush to the pin linkplate prior to pin extraction to ensure that the chain bushing will not be damaged. Place the jaws of the tool over the roller with the push-out pin centered on the chain pin. Tighten down by turn-ing the top handle clockwise until the chain pin loosens, driving it partially through the linkplate. Follow the same procedure on the other pin. Return to the original pin and force completely through the pin linkplate. Do the same on second pin, freeing linkplate from the pins. Remove disassembled pin link from the chain.
USING THE ASSEMBLY AND DISASSEMBLY TOOLS
WARNING WHEN ASSEMBLING OR DISASSEMBLING CHAIN:
• ALWAYS SHUT OFF POWER AND LOCK OUT GEARS AND SPROCKETS BEFORE ATTEMPTING TO REMOVE OR INSTALL CHAINS.
• ALWAYS USE SAFETY GLASSES TO PROTECT YOUR EYES.
• WEAR PROTECTIVE CLOTHING, GLOVES, AND SAFETY SHOES.
• SUPPORT THE CHAIN TO PREVENT UNCONTROLLED MOVEMENT OF CHAIN AND PARTS.
• TOOLS SHOULD BE IN GOOD CONDITION AND PROPERLY USED.
• TOOLS ARE NOT MADE TO SUPPORT TOTAL WEIGHT OF CHAIN, ONLY TO TAKE UP SLACK.
• NEVER USE EXTENSION ON HANDLE WHICH COULD OVERLOAD DEVICE AND CAUSE POSSIBLEINJURY.
• DO NOT ATTEMPT TO CONNECT OR DISCONNECT CHAIN UNLESS YOU KNOW THE CHAIN CONSTRUCTION, INCLUDING THE CORRECT DIRECTION FOR PIN/RIVET REMOVAL OR INSERTION.

ROLLER CHAIN WEAR
Chain does not “stretch” – elongation is caused when material is removed from the pins and bushings.
The individual joints in a roller chain articulate as they enter and exit the sprockets. This articulation results in wear on the pins and bushings. As material is worn away from these surfaces, the chain will gradually elon-gate.
Elongation ControlElongation is normal and may be minimized through proper lubrication and drive maintenance. The rate of wear is dependent upon the load and the amount of bearing area between pin and bushing, the material and surface condition of the bearing surfaces, the adequacy of lubri-cation, and the frequency and degree of articulation between pins and bushings. The latter is determined by the quantity of sprockets in the drive, their speeds, the number of teeth, and the length of the chain in pitches.
Check Chain WearRoller chains should be replaced when worn (elongated beyond 3%) or when the chain rollers begin to “ride high” near the tips of the teeth on relatively large sprockets. Do not connect or splice a new section to a worn chain. Do not continue to run a chain worn in excess of 3% (or less in some applications), the chain will not engage the sprockets properly and increased damage to the sprockets may occur.

HOW TO MEASURE CHAIN WEAR
1) As a safety precaution, shut off power and lock out gears and sprockets before attempting to measure chain wear.
2) Determine the pitch of the chain. This is typically stamped on the outer linkplates of the chain. It can also be determined by measuring thedistance from the center of one pin to the center of the next pin. Refer to the Diamond Chain product catalog for a list of ANSI standard chainmodels and correlating pitch measurements or visit www.diamondchain.com.
3) For reliable linear measurement, a taut span of chain must be used. Using slack chain will result in inaccurate measurements.
4) Choose either a 1.5% or 3% wear elongation limit to check your span of chain. Each percentage correlates to a different side of the scale. The maximum allowable wear elongation is typically 3% for most industrial applications, depending upon sprocket design. In drives having fixedcenter distances, chains running in parallel, or where smoother operation is required, chain wear should be limited to approximately 1.5%.Example: Using ASME/ANSI 60 roller chain, 13 pitches would measure 9.75 inches for nominal length (13 pitches x .75 pitch). A maximum wear calculation of 3% would be 1.03 x 9.75 or 10.0425 inches. A maximum wear calculation of 1.5% would be 1.015 x 9.75 or 9.896 inches.
5) Refer to the table on the wear gauge for the number of pitches to inspect. Themore pitches (pins) included in the measurement provides the truer representation of the average amount of wear distributed throughout the chain. Example: For ASME/ANSI 60 roller chain, 13 pitches will be measured.
6) Place the inside corner of the wear scale around one pin, using that pin as “0,” or your starting point.
7) Starting at “0,” count the number of pins/pitches to be measured for your chain’s length. Example: Count from 0 to 13 for ASME/ANSI 60 roller chain.
8) If the center of the indicated pin does not reach the wear line for the correspond-ing chain size, the chain has not reached the wear limit. Example: For ASME/ANSI 60 roller chain, if the center of the 13th pin does not reach the # 60 wear mark, the chain remains usable.
9) If the center of the indicated pin is at or beyond the indicated line, the chain isworn to the wear limit (1.5% or 3%, depending on the scale used) and should bereplaced. Example: For ASME/ANSI 60 roller chain, if the center of the 13th pin reaches or exceeds the # 60 wear mark, the chain should be replaced.
