21309 CC K (tapered) W33 Spherical Roller Bearing

With the swiveling inner ring, the spherical roller bearing 21309-CC-K-W33 offers excellent alignment error compensation. It has two rings with barrel-shaped rollers as rolling elements and can absorb very high radial and also axial forces.

Features

  • Spherical roller bearing with two rows of rollers
  • pivoting inner ring, misalignments and shaft deflections can be compensated
  • suitable für very high radial and relatively high axial loads in both directions
  • medium series with compact dimensions and average weight
  • with tapered bore for mounting by means of adapter sleeve
  • cage material: sheet steel. Resistant to fatigue and wear; provide good protection against impact loads and acceleration forces
  • seal: open (without seal); for higher speeds than with sealed spherical roller bearings and easy relubrication
  • good fixed bearing property, but can also be used as a floating bearing, each in both directions
