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.
