Tritan 50BS20H 20T 50 Chain Sprocket 1 1/8 Bore Keyway

Power Transmission Sprocket

This finished-bore sprocket transmits rotary motion for #50 roller chain in industrial and agricultural drives. It fits a 1 1/8 inch shaft and includes two set screws to lock the hub in place. Buyers who need a different chain pitch or a larger bore diameter must select another part.

20-Tooth Steel Hub

The 20-tooth steel hub delivers a 3.995 inch pitch diameter and a 4.32 inch outside diameter. A 1/4 inch wide by 1/8 inch deep keyway prevents rotation on the keyed shaft. Builders who require more teeth for a higher speed ratio or a different hub projection cannot use this sprocket.

Black Oxide Finish Under Load

Black oxide coating resists corrosion during continuous operation in dirty or damp environments. The 1 inch length through bore and 0.657 inch hub projection keep the chain aligned over long duty cycles. Operators who expect extreme shock loads or need a stainless-steel body should choose an alternative design.
