Short pitch precision Stainless Steel Roller Chains (B series)
Our stainless steel roller chain is constructed using strict ANSI standards. Our roller chain utilizes a solid roller design to ensure a long life for the chain. Also, our chain is heat-treated and pre-stressed. Our stainless is constructed with 304 stainless steel. Products are made of high-quality alloy steel production. The plates are punched and squeezed bores by precision technology. The pin, bush, and roller are machined by high-efficiency automatic equipment and automatic grinding equipment, then through heat treatment of carburization, carbon, and nitrogen protection mesh belt furnace, surface blasting process, etc. Assembled precision by Internal hole position, spin riveted by pressure to ensure the performance of the entire chain.
