For Montabert HC50 rock drills, part number 86344116, bearing housing in the hydraulic rotary motor.

Bearing Housing 86344116 for Montabert HC50 Rock Drill Hydraulic Rotary Motor

The bearing housing (part number 86344116) is used in the hydraulic rotary motor of the Montabert HC50 rock drill. It is an important support component that holds and protects the bearings inside the rotation system, helping the motor run smoothly and maintain stable torque transmission during drilling.

This housing is designed to keep the bearings correctly aligned while protecting them from heavy vibration, impact loads, and contamination generated during rock drilling operations. A stable bearing housing is essential for maintaining smooth rotation and reducing unnecessary wear on the rotary motor assembly.

Made from high-strength alloy steel, the housing is precision-machined for accurate fitment and long service life. It is built to work under tough conditions such as continuous drilling, high hydraulic pressure, and heavy-duty underground applications.

From Our Experience

If the bearing housing becomes worn or damaged, the rotary motor may develop unstable rotation, abnormal noise, or premature bearing failure. In serious cases, it can also affect gear alignment and damage other rotating parts. Replacing worn housings in time helps keep the drill running smoothly and reduces maintenance costs.

Why Quality Matters

A well-machined bearing housing helps:

• Extend bearing service life
• Keep rotation stable under load
• Reduce downtime and repair costs
• Improve overall drilling efficiency

For heavy drilling jobs, reliable rotary motor parts are important for maintaining stable performance and avoiding unexpected breakdowns underground.
