They can only withstand axial loads and cannot withstand any radial loads.
Separable and interchangeable
The separation components of thrust ball bearings are interchangeable. This facilitates installation, disassembly, maintenance, and inspection.
Initial misalignment
Bearings with spherical race rings can adapt to initial misalignment.
Interference fit
The shaft ring is equipped with grinding holes to achieve interference fit. The seat ring hole is machined by turning and always larger than the shaft ring hole.
