Tapered roller bearings

Short Description:

Tapered roller bearings mainly bear radial-based radial and axial combined loads. Axial load carrying capacity of single row tapered roller bearings depends on contact angle, that is, angle of outer ring raceway, the greater the angle the greater the carrying capacity.Tapered roller bearings are capable to bear axial load in one direction and to limit axial displacement of shaft and housing in one direction. Compared with angular contact ball bearings, tapered roller bearings loading capacity...

Tapered roller bearings mainly bear radial-based radial and axial combined loads. Axial load carrying capacity of single row tapered roller bearings depends on contact angle, that is, angle of outer ring raceway, the greater the angle the greater the carrying capacity.Tapered roller bearings are capable to bear axial load in one direction and to limit axial displacement of shaft and housing in one direction. Compared with angular contact ball bearings, tapered roller bearings loading capacity is greater, limiting speed is low. Tapered roller bearings are widely used in automobiles, rolling mill, mining, metallurgy, plastic machinery and other industries.
