Precision CNC Machining for Gearbox Housings

Precision CNC Machining for Gearbox Housings

Tight-tolerance gearbox housings with accurate bearing bores, mounting faces, and shaft alignment.

Gearbox housings demand precise bearing bores, mounting faces, and shaft alignment. We machine tight-tolerance housings to ±0.0005″ true position with consistent flatness, fast quoting, and production-ready workflows that prevent misalignment, noise, and premature gearbox failures.

Precision CNC Machining for Gearbox Housings

We machine gearbox housings where accurate bearing alignment, mounting geometry, and sealing interfaces directly affect gearbox life, noise, and reliability. Typical work includes billet and replacement housings with complex bore patterns, split lines, and critical datum schemes.

One-piece billet gearbox housings

Split gearbox housings with doweled mating faces

Replacement housings for worn or cracked cast gearboxes

Housings with multiple bearing bores and stepped pockets

Gearbox casings with integrated mounting feet and pads

Housings with cover flanges, gasket lands, and sealing faces

Gear housings with side-access inspection ports and windows

How We Deliver Consistent, High-Accuracy Results

Stable feature relationships keep bearing bores, shafts, and mounting faces aligned across every housing.

Process plans minimize handling and setups, reducing stack-up error risks and dimensional drift.

Documented workholding and programs ensure repeatable results from first article through long-term production orders.

Capacity planning and standard routings support predictable lead times and reliable release schedules.

Tolerances

Bearing bores and shaft seats held to ±0.0005″ diameter and true position

Critical mounting faces and foot pads held flat within 0.001″ across the housing

Controlled setups and in-process inspection maintain stack-up on prototype and production batches

Tolerances

True position on port patterns and critical bores routinely held to tight, production-grade limits

Flatness control on sealing and mounting faces down to 0.0005–0.001 in, application-dependent

Consistent, documented tolerances maintained across repeat batches and scheduled releases

Common Features

Through-bored and stepped bearing pockets with controlled center distances

Machined mounting feet, flanges, and bolt patterns with repeatable hole position

Cover interfaces, gasket lands, and sealing faces with consistent surface finish
