Our extended pin chains in carbon steel are consisted of solid bushings, solid rollers, and high-precision components that undergo heat treatment and shot peening.
For corrosive environment, we offer different corrosion resistant coatings.
Stainless steel extended pin chain is another choice if the chain is used on food equipment or applications requiring corrosion resistance and clean environment simultaneously.
We also have patented high strength stainless steel chains: MEGA-II series chain with D1 and D3 attachments for higher tensile strength, allowable load and longer working life.
Our self-lube (NSL) extended pin chain is an ideal option for hard-to-reach places or difficulty in lubricating to save you maintenance time and cost.
