When you replace a bearing, the rule of the thumb is to also replace the race it rides. The main reason for this is to ensure that the bearing lasts longer because the wearing will be slow as it runs in the mated surface provided by the matching race.Read More

|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.
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.
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.
