Double - row Cylindrical Roller Bearings

  • This bearing type has large radial load capacity because the raceways and rollers are in line contact with each-other.
  • Since "Rollers" are guided with the "Ribs" of the inner or outer ring, this bearing type can withstand high-speed operation.


Cautions on application

  1. Since there is "no Rib" in the inner or outer ring, there is no axial load capability.
    Please use it as free end side bearing.
