Angular contact ball bearing is a kind of bearing, it can bear radial load and axial load at the same time. Can work at a higher speed. The greater the contact angle, the higher the axial load carrying capacity. High-precision and high-speed bearings usually take 15 degrees contact angle. In the axial force, the contact angle will increase.

Spherical roller bearings with two rows of rollers, the main radial load, but also can withstand any direction of the axial load. Has a high radial load capacity, especially for heavy duty or vibration load, but can not afford pure axial load. This type of bearing outer ring raceway is spherical, so the aligning performance is good, to compensate for coaxial error.

There are two symmetrical spherical roller, the outer ring has a common spherical roller, the inner ring with two inclined axis of the bearing axis of the raceway, with good self-aligning performance, bending or installation when the shaft is not concentric When the bearing can still be used normally, self-aligning with the bearing size series vary, generally allow the adjustment angle of 1 to 2.5 degrees, the type of bearing load capacity, in addition to bear radial load outside the bearing can withstand Bidirectional axial load, with good impact resistance, in general, spherical roller bearings allow the work of low speed.
