Roller Chain - Tsubaki

Roller ChainInstallation & Maintenance3. RS Roller Chain LubricationOne of the most important factors in getting the best possible performance from your roller chain is proper lubrication.Following are some important points to remember:1) The main purpose of lubricating and greasing is to limit wear elongation and prevent corrosion of the chain. Wear elongation arisesfrom wear between the pin and bushing when the chain articulates.2) TSUBAKI roller chain is pre-lubricated before packing. This helps to limit the amount of wear elongation during startup.3) Use of detergents or solvents to clean chain will remove lubricant.3.1 Lubrication Position1) Since chain elongation is caused by wear between the pins and bushings, these parts must be well lubricated.2) The clearance between the outer link plate and the inner link plate on the slack side of the chain should be lubricated with oil. Theclearance between the bushing and the roller should also be done at the same time.Drive ChainFig. 12 Lubrication Position3.2 Lubrication for Lifting chain1) Although there is generally no slack side, lubrication must be done while the chain is not loaded.2) For roller chain that does not articulate, grease should be applied thickly to prevent corrosion. The end fitting connection should alsobe well lubricated, even if there is no movement.3) Since there is a possibility that rain or snow may cause loss of lubrication or corrosion from outdoor use, a protective cover shouldbe attached to the chain.3.3 Recommended Lubrication1) SAE No.Table 1Lubricating SystemA I · A II · BAmbient Temperature –10°C - 0°C 0°C - +40°C +40°C - +50°C +50°C - +60°CChain No.(+14°F - +32°F) (+32°F - +104°F) (+104°F - +122°F) (+122°F - +140°F)RS50 and under SAE10W SAE20 SAE30 SAE40RS60 · 80RS100SAE20 SAE30 SAE40RS120 and over SAE30 SAE40 SAE50–10°C - 0°C(+14°F - +32°F)0°C - +40°C(+32°F - +104°F)+40°C - +50°C(+104°F - +122°F)2) Lubrication in high or low temperature conditions.Please consult Tsubaki Technical Support for more information on lubrication in high or low temperature conditions.SAE50+50°C - +60°C(+122°F - +140°F)SAE10W SAE20 SAE30 SAE40SAE20 SAE30 SAE40CSAE50A-109
