The new self-aligningbearing system Radial location of bearings

The new self-aligning bearing systemconsists of a spherical industrial roller bearing as the locating and a CARB If the load carrying ability of a bearingis to be fully utilised, its rings must be evenly supported around the circum- ference and across the whole width of the raceway. This support must be firm and even and can be provided by a cylindrical or tapered seating.Sufficient support, as well as goodradial location of the bearing, generally requires a tight fit between the bearing rings and the surrounding compo- nents. However, if easy mounting and dismounting is required, or for the one ring of non-locating bearings, a tight fit cannot be applied.Further information on selection offits and accuracy of the bearings seat- ings will be found in the SKF General Catalogue or CD-ROM “SKF Inter- active Engineering Catalogue”. âž” fig ).This bearing system accommodatesmisalignment as well as axial move- ment without generating additional axial forces caused by the friction between the outer ring and housing. Due to the ideal co-operation of both bearings the real load situation is always as predicted.The advantages of spherical rollerbearings and CARB bearings are fully utilised in this bearing system, allowing the performance expected and needed by designers today. The new self-aligning systemenhances reliability and performance. Producers as well as users of ma- chines have clearly reduced costs due to simpler design and increased productivity.More information will be found in theSKF brochure 4417 “Self-aligning bearing systems” .
