Axial location of bearing rings
Bearings with a tapered bore
Depending on conditions and requirements, common ways of axially locating the inner ring of a bearing with a tapered bore are:
- a lock nut for bearings mounted on a tapered seat (fig. 7)
-
an adapter sleeve only (fig. 8), if no precise axial positioning is required and the axial loads do not exceed the friction between sleeve and shaft
-
an adapter sleeve and a distance ring (fig. 9), if precise axial positioning is required or elevated axial loads occur
- a withdrawal sleeve with a distance ring (or shaft shoulder) and lock nut (fig. 10)
Abutments and fillets
When designing abutments, allow enough space to avoid contact between rotating and stationary parts.
Shaft and housing fillet dimensions should always be smaller than the bearing chamfer radii. Heavily loaded shafts can require large fillets and a spacing collar may be necessary (fig. 11).
Appropriate abutment and fillet dimensions are listed in the product tables.
