Gear Housing

The Gear Housing (OEM 3217 3909 80) is a premium aftermarket replacement engineered for rock drilling and drifter rigs operating in the most demanding mining and tunnelling environments. It transfers rotational power between drive components, meshing under load to deliver controlled torque and speed for drilling and feed functions.

Manufactured from case-hardened alloy steel with precision-cut teeth, it ensures smooth power transmission, minimal backlash and high resistance to wear and fatigue. Offered as an aftermarket alternative, it delivers full interchangeability and proven durability at a more competitive cost.
