40 Roller Chain Sprockets

ANSI standards(40 Roller Chain Sprockets) are part of each design, including A-plate, SK-type and P-type varieties. Each #40 sprocket goes through extensive quality assurances so the teeth and hardening practices are up to standard. No other #40 chain sprocket can give you as much durability as our stock.
A #40 sprocket must meet and exceed your standards on the production floor. Try out a #40 chain sprocket with a chain of your choosing. Press the two components together to see a tight yet flexible connection. The chain rolls off each sprocket with ease and grace.
