Self-aligning roller bearing has two rows of spherical rollers, the outer race is provided with a common concave spherical raceway, while the inner race is provided with two concave spherical raceways that form an angle with the bearing axis.
Thrust ball bearing comprises a blowout patch, a seat ring, steel balls and a holder. The ferrule matches axis is called blowout patch, while the ferrule matches housing is called seat ring.
Four-point contact ball bearing is a type of single-row angular contact bearing, and it belongs to separable bearings. The steel balls contact the four points of ferrule, with a contact angle of 35°.
Single-row angular contact ball bearing comprises an outer race, an inner race, a row of steel balls and a holder. This type of bearing can simultaneously subject to radial load and axial load. It can also be
