ANSI Roller Chain and Links for Flat-Belt Pulleys
Also known as leaf chain and counterbalance chain, this chain is used with pulleys rather than sprockets for low-speed pulling and as counterweight chain for machine tools, elevator and oven doors, and forklift masts. Made of interlaced plates held together by rivet pins, it has a higher tensile strength than roller chain and is used with flat pulleys instead of sprockets.
When servicing worn leaf chain, replace the entire chain—do not splice chains together or mix old and new chain.
Clevis connecting links attach your chain to a clevis.

Flush-Mount Screw-Clamp Bushings
Insert these bushings into the bore of your sprocket for flush or recessed mounting. They handle shock loads and have higher torque ratings than self-centering bushings. When you tighten the included clamping screws, the bushing's inner sleeve contracts onto the shaft and the outer sleeve expands to hold your sprocket, pulley, or gear. They can be mounted on shafts with or without keyways.
