Tooth grinding accuracy: German standard DIN9 grade
Module: 5
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. Tooth surface hardness is high, high wear resistance, can be adapted to the reciprocating frequent use of linear transmission motion equipment can also be used for heavy-duty rack and pinion transmission.
