Spherical roller bearings
Standard designs

RKB spherical roller bearings put together our experience in design with proven performance in countless standard industrial applications, where there are heavy loads, moderate speeds and possibly misalignment.

Main types

  • Type CA/CAF

    • Design used for large size bearings, withstanding high radial loads and moderate axial loads in both directions
    • Inner ring with integral side ribs
    • Symmetrical roller profile
    • One-piece double pronged machined brass or steel (CAF) cage with integral slinger guided on the inner ring
    • Lubrication groove and holes in the outer ring
    • Available with lubrication groove and three lubrication holes in the outer ring and six lubrication holes in the inner ring (W513)
    • Available with tapered bore (K/K30 suffixes)
  • Type MB

    • Design used for medium size bearings operating at medium to high speeds, featuring high load carrying capacities
    • Inner ring with integral side and central ribs
    • Two-piece machined brass cage guided on the inner ring
    • Lubrication groove and holes in the outer ring
    • Available with lubrication groove and three lubrication holes in the outer ring and six lubrication holes in the inner ring (W513)
    • Available with tapered bore (K/K30 suffixes)
  • Type MA

    • Design used for medium and large size bearings
    • Inner ring with integral side ribs
    • Symmetrical roller profile
    • Two-piece machined brass cage guided on the outer ring
    • Lubrication groove and holes in the outer ring
    • Optimized separable cage for better performance in case of different rolling element speed
    • Available with lubrication groove and three lubrication holes in the outer ring and six lubrication holes in the inner ring (W513)
    • Available with tapered bore (K/K30 suffixes)
  • Type CC

    • Design used for medium size bearings operating at medium to high speeds and featuring high load carrying capacities
    • Ribless inner ring
