Lube-free chain for hygiene critical applications

14 January 2018

Designed with a special oil-impregnated bush, Tsubaki’s ‘Lambda’ lube-free chain is internally lubricated which extends its operating life without the need for additional maintenance or messy external lubrication. 

To further benefit hygiene critical applications, the recently launched sixth generation chain will be supplied as standard with a food grade lubricant impregnated bush which also has the benefit of increasing the chain wear life by 30%.

By eliminating external lubrication the chain is kept cleaner, making it suitable for use in areas with strict hygiene regulations. While the chain does need some lubrication to avoid premature wear, in the case of Lambda chain microscopic pores in the seamless sintered bush are vacuum filled and the lubricant is held in place where it’s needed most.

It is inevitable that a small amount will migrate to the surface of the chain, which is why food grade lubricant is now supplied as standard with the chain. The lubricant meets all NSF-H1 requirements so can be used in situations where there is the possibility of incidental contact with food.

Lambda chain can be used in temperatures of between -10°C and 150°C as standard, with a heat resistant version available upon request which can be used in temperatures up to 230°C.
