Maintenance Free Roller Chains Maintenance Free Roller Chains ASME/ANSI Standard Self-Lubricating (SL) Chains ASME/ANSI Standard Self-Lubricating (SL) Chains Self-Lubricating (SL) roller chains feature oil impregnated sintered steel bushings, which release oil during operation to the critical Self-Lubricating (SL) roller chains feature oil impregnated sintered steel bushings, which release oil during operation to the critical pin/bushing bearing area, and reabsorb it when the chain is at rest. These chains never need to be lubricated in service and will pin/bushing bearing area, and reabsorb it when the chain is at rest. These chains never need to be lubricated in service and will operate in temperatures from 14 FF to 158 F. Hitachi Self-Lube chains are rollerless and possess oversized sintered steel bushings to 315 F. Hitachi Self-Lube chains are rollerless and possess oversized sintered steel bushings operate in temperatures from 4 which operate on standard ASME/ANSI sprockets. Caution: The ultimate strength and working load ratings of SL series chains are which operate on standard ASME/ANSI sprockets. Caution: The ultimate strength and working load ratings of SL series chains are less than their standard carbon steel counterparts and should be considered when replacing existing carbon steel chains. less than their standard carbon steel counterparts and should be considered when replacing existing carbon steel chains.
