Precision roller screw sets, machined shafts, nuts, bearings, and housings for OEM integration.

Target Buyer:OEMs and engineering teams designing proprietary linear motion mechanisms who need high-precision core components.

Planetary Roller Screw Component Assembly

Best Fit

OEM teams building their own actuator body but needing precision roller screws, nuts, rollers, or machined interfaces.
Machine builders requiring custom screw ends, bearing journals, housings, thrust tubes, or anti-rotation parts.
Supply-chain programs that need drawing-based component manufacturing with inspection records.

Review Before Sizing

Lead, pitch, thread form, material, heat treatment, hardness, surface finish, and precision grade.
End machining, bearing fit, runout, keyway, spline, thread, and interface tolerance requirements.
Assembly responsibility, lubrication state, packaging protection, and incoming inspection method.

Capability Highlights

High-precision roller screw assemblies for drop-in integration
Machined ends and housings customized to your STEP files
Scalable production route for OEM motion designs

Typical Applications

Custom Actuator Build
Machine Tool Integration
Aerospace Mechanisms
Robotic Joint Assemblies

Engineering Focus

Material traceability and hardness verification
Custom thread grinding and end machining tolerances
Bearing alignment and pre-load setup

Key Evaluation Matrix

Metric	Typical Range	Why It Matters
Component Types	Planetary roller screws, inverted roller screws, thrust tubes, bearing blocks.	Provides the building blocks for ultra-high force density motion systems.
Lead Accuracy	ISO Class 3 or Class 5	Ensures high positioning accuracy for precision manufacturing.
Customization	Drawing-based machining	Allows direct drop-in replacement or integration into proprietary envelopes.

RFQ Checklist

Provide 2D drawing or STEP file of required component
Specify precision grade (e.g. ISO 3 / 5)
List annual volume and batch size
Define mating bearing, housing, nut, thrust tube, or actuator body interfaces
Confirm whether incoming inspection needs CMM, lead, torque, or material records

Risk Controls

Fit and tolerance issues in custom assemblies: Inspection plans can include thread geometry, bearing journals, runout, backlash, torque, and axial play before shipment.
Component is quoted without mating-part context: Review adjacent bearing fits, housing datums, preload method, lubrication state, and assembly responsibility.
Receiving inspection rejects undocumented dimensions: Agree CTQ list, drawing revision, certificate format, and sampling plan before production.

Factory Validation Evidence

Thread geometry, lead accuracy, hardness, roughness, bearing journal, and concentricity checks.
CMM and runout records for machined ends, housings, and bearing blocks when required.
Protective packing and traceability labels aligned with buyer receiving inspection.

Buying Notes

Clarify whether the component is for prototype, spare part, drop-in replacement, or production integration.
Provide mating-part drawings so bearing fits and alignment features can be reviewed together.
For repeat orders, agree on inspection sampling, certificate format, and revision-change notification.

Buyer FAQ

Do you supply just the roller screw without the motor and housing?

Yes, we manufacture and supply precision roller screw sets (shaft, nut, and rollers) for customers building their own actuator bodies.

Can you machine the screw ends to our custom drawings?

Yes, we provide fully machined ends per your STEP files or 2D drawings for direct integration into your bearing blocks.

Can components be supplied with inspection reports?

Yes, the package can include material certificates, hardness, roughness, CMM, lead accuracy, runout, torque, backlash, or axial play records when agreed in the RFQ.
