A self-aligning ball bearing is a rolling bearing with self-aligning properties. Its design features a spherical outer ring raceway and two opposing r

Maintenance of self-aligning ball bearings is crucial for ensuring their long-term stable operation

Self-aligning ball bearings with dust covers and seals are pre-filled with an appropriate amount of grease during assembly.

Thrust ball bearings require adequate housing clearance during installation to ensure free rotation, reduce wear, and extend service life.

Available in both single-direction and double-direction types.

Roller bearings mainly consist of four parts: an outer ring, an inner ring, rolling elements (rollers), and a cage.

Cylindrical roller bearings generally cannot withstand large axial forces.

Cylindrical rollers make line contact with the raceway, resulting in a high radial load capacity.

Cylindrical roller bearings feature line contact between the rollers and raceways.

Roller bearings are used in almost all industrial sectors:

High Load Capacity: Roller bearings have a large contact area between the rolling elements and raceways, allowing them to withstand higher radial and
