Size range: XU covers a wider bore range (40mm 384mm); XSU typically starts from 130mm Selection guide: Choose XU for broader size coverage and cost-effective solutions; choose XSU when maximum sealing and compactness are priorities

Yes. Both the inner ring and outer ring can be designed for rotation. The bearing is self-centering on either the inner or outer diameter, giving you complete flexibility in your mechanical design.

Preload is achieved during manufacturing by selecting roller sets with precise dimensional tolerances that create controlled interference between rollers and raceways. This preload eliminates internal clearance for zero-backlash performance while maintaining smooth, low-torque rotation , verified by rotational torque testing before shipment.

For standard sizes in stock,3 to 7 working days. For made-to-order or custom specifications,15 to 40 working days depending on complexity, quantity, and precision grade. Express shipping is available worldwide.

Yes. Detailed dimensional drawings (PDF and DXF/DWG format) are provided upon request. We also offer bearing housing and mounting interface design guidance to ensure proper integration into your equipment.
