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.
