Load directions for Extreme Bearings

Extreme Bearing units are intended for loads acting vertically toward the base plate support. Therefore, if the SS bearing housing is supported over its entire base, loads are limited only by the load limits of the bearinginsert. If loads acting in other directions occur or if the housing is not supported over its entire base area, check that the magnitude of the load is permissible for the bolt assembly joining the machine frame

 

The load capacibility is limited by the bolt fastening

By type EXS and EXL is a tensioner-stud provide. The loadacting can by these SS bearingunits also in opposite direction of the threaded rod. By these

Axial load carrying capacity 

If Extreme Bearigns are mounted on smooth shafts with no fixed abutment, the magnitude of the axial load that can be supported is determined by the friction between the shaft and sleeve. Provided the bearings are correctly mounted, the permissible axial load can be calculated from:

Fap = 0,003 B d           where: Fap = maximum permissible axial load, kN

                                                B = bearing width, mm

                                                d = bearing bore diameter, mm
