Thrust ball bearing
Thrust ball bearing
1) The scope of processing d: φ120~φ1000mm
2) Characteristics:
Thrust ball bearing can be divided into single direction thrust ball bearing ,double direction thrust ball bearing , single direction thrust ball bearing can support axial loads in one direction ,and double direction thrust ball bearing can support axial loads acting in both directions .But both of them must not be subjected to any radial load, and not applicable for high speed.
The installation face of the seat is the spherical bearings (aligning seat-belt or aligning gaskets) ,which is self-aligning , can reduce the influence of installation errors.
