Uxcell 21 Teeth Flat Chain Sprocket Type A 1/2" Pitch, 12mm Bore Carbon Steel

1. Chain Sprockets are normally mounted in a fixed position on a fixed shaft. This Type A chain sprocket has no hub extension either side. Suitable for short shaft fixing.
2. The chain sprocket should not rotate at a greater speed than is allowable for drive sprockets of the same size. Every roller chain sprocket comes with strong teeth that can latch onto the chain. It is suggested that chain sprockets have at least three teeth in mesh with the chain.
3. The product is made of A3 carbon steel. High-frequency quenching treatment of teeth, the surface hardness, wear resistance are significantly improved. The part without quenching retains the original toughness and is easy to further process. It can be processed into different inner diameter sizes according to the requirements of use.
4. Widely used in industrial transmission and transportation. The inner hole can be processed to meet the needs of different shafts. There is an error of ±2mm in the inner hole, please pay attention before purchasing.
