NN 3005 K/SP

Double row cylindrical roller bearings

Double row cylindrical roller bearings are designed for applications with high to very heavy radial loads and medium to high speeds. The SKF product range comprises a wide range of designs and types, such as standard and full complement rollers as well as pre-filled grease and sealed bearings. Depending on the construction of the inner and outer rings, the bearings are available in locating and non-locating designs.

  • High or very high radial load capacity
  • Very low friction
  • Long service life
