It can bear the axial force in one direction, and has the detachable and interchangeable shaft ring, seat ring and steel ball cage assembly, which is convenient for installation, disassembly and maintenance. Products with spherical seat rings have some self-aligning capability, and can adjust the misalignment impact during installation.

It can bear axial force in two directions, has two steel ball cage assemblies, and can bear ahigher axial load. Products with spherical seat rings have some self-aligning capability, and can adjust the misalignment impact during installation.

It can bear the combined axial and radial loads, and has a high bearing capacity, high axial rigidity, low friction performance and good high-speed performance.
