Spherical roller bearings are double row non separable bearings, consisting of a solid outer ring with spherical raceway, a solid inner ring, and drum shaped rollers with retainers. Symmetrical drum shaped rollers can be freely adjusted in the outer spherical raceway. Therefore, it can compensate for the deflection of the shaft and the misalignment of the bearing seat holes. Spherical roller bearings can withstand bidirectional axial forces and high radial forces. They are designed for high load-bearing capacity because they have as many and long drum shaped rollers as possible, and self-aligning roller bearings are also suitable for extremely heavy loads. The optimized fit between the roller and the raceway ensures uniform stress distribution inside the bearing.
Sealed standard self-aligning roller bearings do not come with seals. The self-aligning roller bearings sealed on both sides have a suffix of 2RSR. Lubricating open self-aligning roller bearings can be lubricated with oil or grease. Sealed self-aligning roller bearings are pre installed with lubricating grease that complies with DIN 51502. There is a groove on the outer circumference of the standard sealed self-aligning roller bearing with the prefix WS and three lubrication holes.

The working temperature of self-aligning roller bearings is stable up to+200 ° C. Open type self-aligning roller bearings with metal retainers are suitable for working temperatures ranging from -30 ° C to+200 ° C. Due to limitations of grease and sealing materials, the working temperature of sealed self-aligning roller bearings is -20 ° C to+100 ° C.

Spherical roller bearings are widely used in industrial machinery and transportation equipment under heavy load, vibration, or shaft deflection conditions, and are suitable for fields such as steel, mining, papermaking, metallurgy, wind power, and railways.

We specialize in producing and supplying various types of heavy-duty industrial roller bearings: four column rolling mill bearings, split bearings, self-aligning roller bearings, tapered roller bearings, thrust self-aligning roller bearings, and cylindrical roller bearings. Suitable for large mechanical equipment such as metallurgical steel rolling, mining crushing, engineering machinery, reducers, papermaking, ships, fans, etc., supporting standard models in stock and non-standard customization, providing original factory quality and testing reports, and supporting foreign trade exports.
