cesGear head material 42CrMo is a kind of steel type, belongs to ultra-high strength steel, high strength and toughness, good quenching, no obvious tempering brittleness, high fatigue limit after quality treatment, strong resistance to multiple impacts.
Low temperature impact toughness is good, suitable for a certain strength and toughness of large and medium-sized plastic mold, main uses: manufacturing steel strength, mass cross-section of large forgings, such as locomotive traction gear, supercharger transmission gear, pressure vessel gear and so on
The head rotation is adjustable by 7 teeth and can be adjusted up to 180 degrees, which is flexible and convenient, allowing you to operate freely in small Spaces, and the internal gear swing gap of 72 teeth is smaller.
