However, there are instances when the bearing race does not fit snuggly in the housing. If the race is too lose and friction to hold it is too tight, forcing it could eventually damage the housing requiring an expensive repair. But there is a simpler way to get it right.

General Description
Roller end / flange contact area

SKF cylindrical roller bearings have two integral flanges on either the inner or outer ring to guide the rollers. The bearings have "open" flanges, i.e. the inward face of the flange is inclined by a defined angle. The flange design, together with the roller end design and surface finish, promote the formation of a lubricant film to reduce friction and frictional heat.

Logarithmic roller profile

The roller profile determines the stress distribution in the roller/raceway contact area. As a result, the rollers in SKF cylindrical roller bearings have a logarithmic profile to distribute loads evenly along the rollers. This prevents peak stresses at the roller ends to extend bearing service life. The logarithmic profile also reduces sensitivity to misalignment and shaft deflection.

Surface finish

The surface finish on the contact surfaces of the rollers and raceways maximizes the formation of a hydrodynamic lubricant film and optimizes the rolling motion of the rollers. The benefits derived from this, compared with traditional designs, include enhanced operational reliability.

Interchangeable components

The separable components of same-sized SKF cylindrical roller bearings are interchangeable. Any bearing ring with a roller and cage assembly can be assembled with any removable ring of the same bearing type and size having the same internal clearance class. This is particularly important when bearings and their components must be mounted independently of each other.
