SKF single row 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 cage design and material
The configuration of the inner and outer ring flanges (fig. 1).
Designs and variants
Features and benefits
Low friction (Roller end / flange contact area)
The open flange design (fig. 2), 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. 3) 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 (fig. 4). 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.
