    Product Description
    Powder metallurgy 17-teeth crankshaft timing sprocket.
    The crankshaft timing sprocket belongs to the automobile engine gas distribution system accessories, which is equivalent to the timing belt wheel. The advantage of the timing chain is that the durability is better than the timing belt, but because of the transmission ratio requirement, the requirement of the sprocket is slightly higher, which requires induction hardening or heat treatment. This product is made of iron cooper steel with a macroscopic hardness of 30-40hrc.Due to the limitation of induction hardening, we recommend the overall heat treatment.
