Spherical Roller Thrust Bearings
Spherical roller thrust bearings can be angularly adjusted and can compensate angular misalignments between shaft and housing due to the concave outline of shaft and housing raceways and the asymmetrical barrel-shaped rollers. They can absorb very high axial forces from a single direction as well as radial forces and are suitable for relatively high speeds despite high loads. Cage, roller cage assembly and shaft washer are self-latching, so they can be assembled separately from the housing washer.
Compensation of angular misalignments
Absorption of high axial forces from one direction
Suitable for medium speeds
Dimensions and Tolerances
The boundary dimensions of the bearings are standardised in ISO 104, DIN 616 and DIN 728. ALPHA Wälzlager GmbH supplies single direction cylindrical roller thrust bearings with normal tolerance (PN) in accordance to DIN 620-3 and ISO 199. Please contact our technical department to check the availability of bearings with improved accuracy class or special tolerances.
Clearance for single direction cylindrical roller thrust bearings is adjusted after installation according to operating conditions.
