Gearbox Materials

1. Housing: die-cast aluminum alloy (Housing size: 025-090); cast iron (Housing size: 110-150)

2. Shaft: 20Cr, carbonize and quencher heat treatment make the hardness of gear tooth surface up to 56-62 HRC, retain carburization layer’s thickness between 0.3-0.5mm after precise grinding

3. Worm Wheel: Wearable bronze alloy


Surface Painting

For Aluminum Alloy Housing

1. Shot blasting and special antiseptic treatment on the aluminum alloy surface

2. After phosphating, paint with blue or sliver.

For Cast Iron Housing

Before paint with blue or sliver, need paint with red antirust pain first.
