The Accuracy Is on the Inside
A housing's outside can look like a simple box, but its job is internal: it positions bearings, gears or a shaft on a precise axis, seals against the environment, and bolts to its mating part. So the features that matter are the bores and their concentricity, the bolt pattern, and the sealing faces. Machined from solid billet — not cast — a CNC housing has no porosity and can be made as a single one-off without tooling.
Custom Housing Specifications

| Finishes | Anodize, powder coat, bead blast, passivate |
Housing Types We Machine
- Bearing housings — pillow-block and flanged, bores to H7
- Gearbox & pump housings — multi-bore, concentric, sealed
- Sensor & electronics enclosures — sealed, with glands and lids
- Valve & instrument bodies — see our hydraulic valve body
- Motor & actuator housings — with register spigots
Material & Sealing
6061 aluminium is the usual choice — light, machinable, anodizable; steel or stainless where load or environment demands. We machine flat sealing faces and O-ring grooves so the housing seals, and verify bore concentricity and position on inspection.
Cracked or discontinued housing? Send the old one or photos with dimensions; we measure (and 3D-scan complex shapes), rebuild it, and machine a replacement from billet — stronger than the original casting. See reverse engineering.
Frequently Asked Questions
Yes. We measure bores, bolt pattern, faces and envelope (CMM + 3D scanning), rebuild the geometry, and machine a new one. Cracked areas are reconstructed to nominal. No drawing needed.
Shared-axis bores are machined in one setup or from a common datum to stay concentric and parallel — essential for bearing and gearbox housings. Verified on inspection.
Yes — flat sealing faces, O-ring grooves, gasket lands and tapped holes for lids/glands. Aluminium can be anodized or powder-coated for the environment.
6061 aluminium for light housings, steel for loaded bearing/gearbox cases, stainless for corrosion/hygiene. Machined from billet — no casting tooling.
