Polymer bush chain, intended for heavy-duty applications, needs no lubrication and has a polymer sleeve between the pin and the bush for high wear and fatigue resistance.

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 environments where heavy-duty applications are exposed to the elements, where wash-down procedures occur, where lubricant would contaminate product and in environments where contaminants could stick to lubricated chain and cause problems.

The new polymer bush chain extends Renold's Syno range, which also includes stainless steel chain, for corrosion resistance, and nickel-plated chain for hygiene-sensitive applications.

The new Polymer Bush chain is manufactured to both BS and ANSI standards.

Sizes range from 1.75 to 2.5in pitch for BS chain and 1.5 to 2.5in pitch for ANSI chain.
