SWBTEC supplies cross roller slewing bearings for equipment that needs compact support for combined axial, radial, and overturning loads.
Choose a standard cross roller design for dependable rotary load support or a high-precision version when runout, stiffness, and controlled motion matter. Share your load cases, interface drawing, and operating cycle to receive a matched wholesale quotation.
A cross roller slewing bearing combines structural connection, load transfer, and relative rotation in one support position. Its suitability depends on the complete load case and installation system, not on the product name alone.
State whether the quotation covers a bearing only, a bearing with internal or external gear, or a wider assembly. Motors, gearboxes, pinions, bolts, guards, and controls are separate items unless the offer says otherwise.
Crossed rollers are a candidate when compact geometry, combined loading, or rotary accuracy is important. A standard load-supporting design and a high-precision design should not be compared by outside diameter alone.
For a replacement or repeat order, keep the complete model, drawing revision, mounting interface, rotating ring, lubrication arrangement, and inspection requirements together. A similar nominal size does not prove interchangeability.
Use this route when the application needs reliable rotary load support and does not require precision positioning as the primary objective. Single-row crossed rollers support axial, radial, and overturning loads through a compact layout. The selection still needs review of long-term wear and partial-load sensitivity.
Use this route when runout, stiffness, clearance or preload, and controlled motion affect the equipment result. The listed high-precision options include RU/XSU-type designs, GCr15SiMn material, and axial/radial runout of no more than 0.005 mm. Confirm the exact measurement condition and acceptance value in the current drawing.
Choose the configuration after the interface and load data are defined. Without-gear, external-gear, and internal-gear versions change the envelope, drive interface, lubrication, inspection, and installation requirements.
The two products below cover the standard and high-precision routes described on this page. Open the product details for the source tables, then send the selected link, operating conditions, and interface data with your inquiry.
For precision rotary assemblies that require controlled runout, stiffness, and compact cross-roller support. Confirm the exact series, fit, and measured accuracy in the quotation package.
For rotary tables and other rotating equipment where dependable combined-load support is more important than precision positioning. Review duty cycle, partial loading, wear, and installation conditions before selection.
A useful wholesale quotation starts with the inputs that control load capacity, accuracy, fit, and delivery scope.
| Input | What to provide | Why it matters |
|---|---|---|
| Load case | Axial force, radial force, overturning moment, normal/max/impact conditions | Determines the combined-load check and support requirements. |
| Motion | Continuous rotation or oscillation, speed, angle, cycle, starts/stops, daily hours | Changes lubrication, wear, temperature, and service-life assumptions. |
| Interface | Inner/outer diameter, height, bolt holes, locating features, fixed and rotating rings | Controls fit, mounting, envelope, and interchangeability. |
| Accuracy and stiffness | Runout, clearance or preload, friction torque, positioning or repeatability target | Separates a standard load-supporting choice from a precision design. |
| Environment | Temperature, dust, water, corrosion, cleaning, storage, lubricant constraints | Sets the sealing, material, lubrication, and protection requirements. |
| Commercial scope | Quantity, inspection documents, packaging, destination, Incoterms, target delivery | Aligns the wholesale price and lead-time comparison. |
For a replacement, attach the approved drawing or a dimensioned interface record. Verify the full circumference, mounting structure, bolts, lubrication, and gear interface before treating a model as interchangeable.
SWBTEC describes technical support from selection and drawing quotation through shipment and after-sales communication. For a purchase decision, convert that support into a document list tied to the selected model and revision.
Depending on the project, request the current drawing, material and heat-treatment information, dimensional and runout results, clearance or preload data, gear inspection, lubrication state, and traceability. A general company certificate does not replace product-specific acceptance evidence.
Cross roller bearing pricing changes with diameter, section, material, accuracy, interface changes, quantity, inspection documents, packaging, and shipping terms. Compare offers only after those boundaries are aligned.
Confirm whether the quote covers a standard catalogue item, a modified interface, or a new design. Record drawing revision, quantity, delivery destination, packaging, and required files so a wholesale order can be repeated without changing the technical basis.
No fixed price is shown because diameter, section, material, accuracy, interface, quantity, inspection documents, packaging, and shipping conditions affect the quotation. Send those inputs for a comparable offer.
Start with the selected product link or drawing, axial/radial/overturning loads, motion cycle, mounting dimensions, fixed and rotating ring, gear requirement, environment, quantity, and destination.
Not by default. A cross roller slewing bearing is the support and rotation component. Confirm separately whether gears, pinions, drives, bolts, guards, or controls are included.
Choose the high-precision route when runout, stiffness, clearance or preload, friction torque, or positioning performance affects the equipment. The exact acceptance values should be defined on the current drawing and inspection plan.
Check the complete model and revision, inner and outer diameters, height, hole pattern, locating features, gear details, rotating ring, clearance or preload, load case, lubrication, sealing, and installation structure. Nominal outside diameter alone is not enough.
