Heat treatment hardness:50-53HRC
Pre-balance is G6.3-18000rpm,G2.5-20000rpm
Thread and a slope of 30 degrees have once molding processing.
The tolerance class of thread use 4H,accuracy detected one by one.
Cryogenic treatment and thermal aging treatment have improve the stability of accuracy and dimensions.
Surface coating processing treatment,improve the surface hardness hardness and endurance ,anti-rust and anti-corrosion better,accuracy stable,more smooth,feel more comfortable,appearance nice.
