Lightweight Idler Sprockets for ANSI Roller Chain
Made of nylon, these sprockets are lightweight, quiet, and corrosion resistant. Designed to rotate freely on built-in bearings, idler sprockets maintain constant tension on your drive by pressing against your chain to take up slack and reduce wear and vibration. They are for use with roller chain tensioners. Bearings are double sealed to keep dirt out.

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.
