Split Housing CNC Machining – Tight-Tolerance Production

Split Housing CNC Machining – Tight-Tolerance Production

Tight-tolerance split housing machining with aligned bearing bores and flat sealing faces.

We machine split housings to tight tolerances, keeping halves aligned for reliable sealing and bearing life. Typical bores hold ±0.001″ and sealing faces stay flat within 0.0015″. Fast quotes and production-ready processes reduce outage risk.

Precision CNC Machining for Split Housings

Split housings in pump, gearbox, motor, and bearing assemblies demand accurate bore alignment, flat split lines, and repeatable clamping geometry to avoid premature failures and leakage in service.

Pump and compressor split housings

Gearbox and speed reducer split cases

Electric motor and generator split housings

Split bearing housings and pillow block assemblies

Compressor and blower casings with split joints

Split housings for large rotating shafts and couplings

Retrofit and replacement split housings for legacy equipment

How We Deliver Consistent, High-Accuracy Results

Matched machining of both halves keeps bearing bores and sealing faces aligned across the split line.

Process plans minimize re-clamping, reducing setup moves that can stack tolerance error into critical features.

Documented offsets and inspection routines lock in bore-to-bolt relationships for repeatable multi-batch production.

Standardized workflows and realistic slotting give predictable lead times instead of emergency rush machining.

Technical Capabilities

Materials

4140/4340 alloy steel split housings for heavy-duty bearing and gearbox applications.

1018/1045 carbon steel housings where machinability and strength must balance.

{{bullet6061 and 7075 aluminum split housings for weight-sensitive equipment.}

Tolerances

Critical bearing bores routinely held to ±0.0005″–±0.001″ with matched halves.

Split-line sealing faces machined flat within 0.0015″ across the assembled housing.

Prototype runs to 500+ piece batches using controlled setups and in-process inspection.

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

Opposed bearing bores and journals that must stay concentric through the split line.

Split-line sealing faces, gasket lands, and O-ring grooves for leak-tight assemblies.

Dowel holes, bolt patterns, and alignment features that control housing registration in the field.
