About this item

  • Specifications: Hardness: 58-60HRC; Number of Teeth: 18; Outside Diameter: 77mm / 3.03-inch; Total Width: 7mm / 0.28-inch; Bore Diameter: 12mm / 0.47-inch; Pitch: 1/2-inch / 12.7mm; Tooth Width: 7mm / 0.28-inch; 1 x Chain Sprocket
  • 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.
  • 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.
  • 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.
  • Notice: This product is a blank piece and cannot be used directly. The inner hole needs further processing to be fixed.

I ordered two sprockets, both of the center bores were off center by a considerable amount. Not a huge deal for me since I bored them out to 1.125" on my lathe, but getting them perfectly centered without the ability to reference the center bore was a pain. If you plan to weld them straight to a shaft without any machining, make sure the bores are not off center.
