crossed roller slewing bearing factory
SWBTEC manufactures crossed roller slewing bearings for rotating assemblies that need one compact bearing position to carry radial load, axial load, and overturning moment. The range includes high precision rings for controlled rotary motion and larger slewing rings for industrial equipment.

What Our Factory Supplies
Ningguo SwbTec Industry Co., Ltd. supplies crossed roller bearing rings under the SWBTEC brand. In a crossed roller arrangement, adjacent cylindrical rollers alternate orientation within the raceway. The arrangement supports loads in multiple directions at one bearing location, while the final capacity and running accuracy depend on the chosen series, internal clearance or preload, and the surrounding structure.
Our two product routes cover compact high precision rings and larger cross roller slewing bearings. Both are bearing components for integration into your machine. The mating structure, drive, seals, and lubrication plan should be reviewed with the selected bearing rather than assumed from the bearing name alone.
Choose the Bearing Configuration
Start with the required bore and outside diameter, the combined load case, and the acceptable runout. A compact precision ring is a strong candidate when rotary positioning and a tight installation envelope drive the design. A larger slewing ring is more appropriate when the assembly needs a wider mounting circle or a gear interface.
| Decision point | High precision cross roller ring | Cross roller slewing ring |
|---|---|---|
| Typical design focus | Controlled rotation in a compact assembly | Larger diameter rotation and structural integration |
| Catalog information | Bore, outside diameter, width, mounting data, load rating, and speed by series | Ring dimensions, mounting holes, gear data when applicable, and mass |
| Common applications | Robot joints, precision rotary tables, and machine tools | Industrial turntables and rotating machinery |
| Key review | Runout, stiffness, clearance or preload, and mounting flatness | Combined loads, gear choice, bolt pattern, and support rigidity |
Catalog dimensions narrow the choice; a final selection should use the actual axial and radial loads, overturning moment, duty cycle, and mounting arrangement. Preload can increase stiffness while raising friction and sensitivity to mounting error.

Data We Need to Size and Quote Your Bearing
A useful RFQ links the machine duty to the bearing drawing. Share the information below so the proposed ring can be checked against your space, load, and interface requirements.
| Input | What to provide | Why it matters |
|---|---|---|
| Loads and motion | Axial and radial forces, overturning moment, speed, duty cycle, and shock loads | Defines the load case and bearing life assessment |
| Envelope | Bore, outside diameter, ring height, and available installation space | Sets the candidate series and cross section |
| Mounting interface | Bolt circles, holes, locating features, support surfaces, and shaft or housing drawing | Controls fit and ring distortion after installation |
| Running requirement | Runout, rotational torque, stiffness, and preferred clearance or preload | Guides precision level and assembly adjustment |
| Environment and delivery | Temperature, contaminants, lubrication approach, quantity, and destination | Guides sealing, grease, packaging, and quotation scope |
Manufacturing and Inspection Controls
SWBTEC records checks through ring processing, assembly, and final inspection. The control points depend on the bearing design and the drawing requirements.
Ring processing
Incoming forgings are checked for appearance and dimensions. After rough turning, ultrasonic inspection can identify internal flaws. Raceway machining and induction hardening are followed by hardness, case depth, and crack checks where specified.
Precision finishing and assembly
Finishing controls ring geometry, wall thickness, and flatness. Before assembly, parts are cleaned and deburred; rollers, cages, seals, and other components are installed to the approved drawing. The assembled bearing is checked for smooth rotation and unusual noise.
Release inspection
Depending on the model, final records can cover dimensions, mounting holes, clearance, axial and radial runout, raceway hardness, and gear measurements. Request the inspection items and acceptance limits needed for your equipment in the RFQ.
Applications and Mounting Conditions
Precision crossed roller rings are used in robot joints, machine tool rotary axes, and other positioning equipment. Larger cross roller slewing rings can support industrial turntables and machinery that applies a combined axial, radial, and moment load to one rotating joint.
The bearing and its support structure work together. Uneven mounting faces or uneven bolt loading can distort the rings and change running torque or runout. The housing and mating structure should provide adequate stiffness, and the installation plan should specify fasteners, lubrication, sealing, and access for service.
For a replacement, send the existing bearing drawing or part number with measured mounting dimensions. A visually similar ring may have different internal clearance, bolt pattern, gear geometry, or load capacity.
From Drawing Review to Delivery
- Submit the application data. Share a drawing or existing part number, load case, required precision, quantity, and delivery destination.
- Confirm the proposal. Review the bearing series, dimensions, mounting pattern, gear option if needed, and the inspection requirements written into the quotation.
- Approve the production drawing. Confirm interfaces and revisions before machining and assembly.
- Review the release documents. Agree on the inspection record, product marking, packing, and shipment information required for your order.
