Roller Bearings

Cylindrical Roller Bearing

SKF cylindrical roller bearings are available in many designs, series and sizes. The major design differences between the bearings presented in this section are in:

• the number of roller rows (one, two or four)
• the type of cage (with, without or special designs)
   - Bearings with a cage can accommodate heavy radial loads, rapid accelerations and high speeds.
   - Full complement bearings (without a cage) incorporate a maximum number of rollers and are therefore suitable for very heavy radial loads at moderate speeds.
   - SKF high-capacity cylindrical roller bearings combine the high load carrying capacity of a full complement bearing with the high speed capability of a bearing with cage.
• the configuration of the inner and outer ring flanges (position and number of guide flanges)

Bearing features

• High load carrying capacity
• High stiffness
• Accommodate axial displacement
  - Except for bearings with flanges on both the inner and outer rings.
• Low friction
  - 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 cylindrical roller bearings are interchangeable. This facilitates mounting and dismounting, as well as maintenance inspections.
