Planetary Roller Screw Housing CNC
Precision machining for roller-screw-adjacent housings and support interfaces where coaxiality and bearing-fit governance drive actuator reliability.
Core bottleneck: Robotics programs can source roller screws slowly, but still fail on downstream housing precision and integration repeatability.
Manufacturable Scope
- Support housing and flange machining for actuator stacks
- Bearing-seat and coaxiality-focused tolerance planning
- Revision-controlled NPI execution for robotics schedules
Representative Part Scope
- Roller screw nut support housing
- Actuator flange and bearing seat structures
- Joint-side load transfer mounting blocks
- Alignment-critical coupling interface parts
Proof Checkpoints
- CMM verification on coaxiality, bore alignment, and datum relationships
- Bore and thread gauge checks against drawing-defined fit classes
- First-article dimensional report prior to pilot lot release
Materials & Process Focus
- Bearing and bore fit stability under load transfer
- Interface concentricity for reduced backlash risk
- Pilot-to-ramp dimensional repeatability controls
Evaluation Matrix
| Metric | Typical Range | Why It Matters |
|---|---|---|
| Coaxiality verification path | CMM + gauge checks on fit-critical features | Small concentricity drift can amplify vibration and reduce actuator lifetime. |
| Assembly-fit repeatability | Drawing-specific fit control by feature class | Reliable pilot builds require stable fit outcomes across successive lots. |
Risk Controls
- Scope confusion with roller screw manufacturing itself: Define offer as housing and integration-structure machining; roller screw core component supply is outside this page scope.
- Tolerance over-constraint inflates cycle time and cost: Split critical vs non-critical feature classes before quote lock.
Buyer FAQ
Do you manufacture planetary roller screws directly?
No. This scope covers high-precision housings and actuator-adjacent integration parts around roller screw assemblies.
Can you support frequent revision updates during NPI?
Yes. Revision-controlled NPI routing is part of the execution model for robotics programs.

Upload CAD and drawings for a one-business-day first response when the RFQ package is complete. We review manufacturing risk before quote direction and partner-route planning, rather than issuing blind automated pricing.
Typical 5-9 working day CNC sample timing applies only after scope, material, inspection, partner route, and schedule are qualified. Pilot support is scoped separately after prototype assumptions are clear.
