KOYO Four-Point Contact Ball Bearings (62..BI, 63..BI)

KOYO Four-Point Contact Ball Bearings (62..BI, 63..BI)

Four-point contact ball bearings with split inner ring (BI suffix) in the 62 and 63 series, carrying axial loads in both directions plus moderate radial loads.

Key features

  • Split inner ring allows a high number of balls
  • Axial load capacity in both directions
  • 62 and 63 series, bore 20-75 mm and above
  • Compact alternative to paired angular contact bearings
