Tooth grinding accuracy: German standard DIN9 grade
Module: 3
Material: C45
Hardness: HRC50-55
Heat treatment: tooth high frequency quenching
The surface of the rack is blackened after high frequency quenching, and the surface of the product is highly rustproof and not easy to corrode. High hardness of tooth surface, high wear resistance, can be adapted to the reciprocating frequent use of linear transmission motion equipment.
