Double row cylindrical roller

Features and benefits

  • 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, 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 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.
