Single Row Angular Contact Ball Bearings

JYHY specializes in large diameter single row angular contact ball bearings with bore sizes ranging from 100 mm to 1320 mm. These bearings are widely used in rolling mills, heavy machinery, mining equipment, gearboxes, marine systems and other demanding industrial applications.

Single row angular contact ball bearings are designed to accommodate combined radial and axial loads while delivering high rotational accuracy and rigidity. Compared with deep groove ball bearings, they provide greater axial load capacity and are widely used in machine tools, pumps, compressors, gearboxes and other industrial equipment.

JYHY supplies large-size angular contact ball bearings with bore diameters from 100 mm to 1320 mm, covering the 70, 72, 73, 718 and 719 series. Many models are available in matched DB, DF and DT arrangements for applications requiring enhanced stiffness and axial load support.

  • Contact angles: 15°, 25°, 30° and 40°
  • Bore diameter range: 100 mm – 1320 mm
  • ABEC-3 to ABEC-7 precision grades available
  • DB, DF and DT matched configurations

Applications

  • Machine tool spindles
  • Industrial pumps
  • Compressors
  • Gearboxes
  • Electric motors
  • Precision machinery
