Double row cylindrical roller bearings

Double row cylindrical roller bearing
SKF double row cylindrical roller bearings are available in several designs with a cylindrical or tapered bore. The SKF standard assortment presented in this section includes:

Bearing features

  • High load carrying capacity
    Because of their second row of rollers, double row cylindrical roller bearings are suitable for heavy radial loads.
  • Low friction (Roller end / flange contact area)
    The open flange design (fig. 4), together with the roller end design and surface finish, promote lubricant film formation resulting in lower friction and higher axial load carrying capacity.
  • Long service life
    The logarithmic roller profile reduces edge stresses at the roller/raceway contact (fig. 5) and sensitivity to misalignment and shaft deflection.
  • Enhanced operational reliability
    The surface finish on the contact surfaces of the rollers and raceways supports the formation of a hydrodynamic lubricant film.
  • Separable and interchangeable
    The separable components of SKF double row cylindrical roller bearings are interchangeable. This facilitates mounting and dismounting, as well as maintenance inspections.
  • High speed capability
    The cage designs are suitable for high speeds, rapid accelerations and peak loads.
