Single Row Angular Contact Ball Bearings

Single row angular contact ball bearings are designed to support combined radial and axial loads, with axial load capacity in one direction. The optimized contact angle provides higher axial load capability and precise shaft guidance compared to deep groove ball bearings.
Lumi manufactures high-quality single row angular contact ball bearings with precision-ground raceways and controlled contact angle geometry, ensuring smooth operation, stable running accuracy, and reliable performance under high-speed and high-load conditions.
Our single row angular contact bearings are available in various sizes, contact angles, and cage designs, with open, shielded, or sealed configurations. They are widely used in machine tools, pumps, compressors, gearboxes, and other precision industrial equipment.
Lumi also offers OEM / ODM customization services, including contact angle selection, internal clearance control, cage material optimization, sealing solutions, and lubrication design, to meet specific application requirements.
