Specialty Roller Chains
Specialty roller chains are manufactured for applications that may require a particular chain feature that standard chains don't offer. The specialty chains are fully interchangeable with ANSI standards chains and sprockets.
O-Ring Roller Chain
These chains are great for dusty environments or where standard re-lubrication may difficult. There is an o-ring pinched between the two plates to hold lubrication on the chain joint while keep abrasive material out.
Hollow Pin Roller Chain
Hollow pin chains are great for conveyor applications that requires the need of attaching pins or rods directly into the chain
Non-Standard Roller Chain
Non-standard roller chain is line of chains that carry different dimensions that an ANSI roller chain. Even though these are considered "non-standard", these chains are actually quite common in the power transmission industry.
