SKF sealed spherical roller bearings wholesaler

SKF spherical roller bearings have two rows of rollers, a common sphered outer ring raceway and two inner ring raceways inclined at an angle to the bearing axis. With the exception of bearings designated with a BS2- prefix, the boundary dimensions of sealed spherical roller bearings are in accordance with ISO 15. Bearings with a BS2- prefix, for example BS2-2214-2CS, are based on 222 E or 223 E series bearings, but are slightly wider to accommodate the seals.

SKF sealed spherical roller bearings have the same features and internal design as basic design spherical roller bearings and are available with a cylindrical bore as standard. Some sizes are also available with a tapered bore or can be supplied with a tapered bore on request.

SKF sealed spherical roller bearings have a contact seal reinforced with a sheet steel insert, fitted on both sides. They can also be supplied with a seal on only one side. The bearings can be fitted with seals made of one of the following materials:

  • NBR (designation suffix CS)
  • HNBR (designation suffix CS5)
  • FKM (designation suffix CS2)

The seals are fitted in a recess on the outer ring and seal against the inner ring. On larger bearings, the seals are fixed by a retaining ring.

Sealed spherical roller bearings are supplied lubricated and should not be washed. For many application conditions, the bearings do not require relubrication and can be considered relubrication-free (→ Relubrication of sealed bearings).
