Lubricant-free chain for heavy-duty applications.(workshop)

Renold Chain has extended its Syno range of lubrication-free chains with the development of a polymer bush chain, for heavy-duty applications, that requires no lubrication at all. The chain is designed with a specially developed polymer sleeve that fits between the pin and the bush for high wear and fatigue resistance. Another specially developed polymer has been produced for the chain's rollers that have excellent impact resistance and load bearing capabilities. With a corrosion resistant surface treatment the new Syno Polymer Bush chain is able to operate without lubrication in
