Bearings are mainly divided into two categories: rolling bearings and plain bearings, of which rolling bearings can be subdivided into 14 common types according to structural and functional differences, including deep groove ball bearings, angular contact ball bearings, self-aligning ball bearings, cylindrical roller bearings and so on.
Main types of rolling bearings
Deep groove ball bearings: the most versatile type of bearings, can withstand radial load and a small amount of axial load, small coefficient of friction, high limiting speed, widely used in automobiles, agricultural machinery and other fields.
Angular contact ball bearings: the contact angle (15°-40°) determines its axial load carrying capacity, suitable for machine tool spindle or need two-way force scene, often used in pairs.
Self-aligning ball bearings: the outer ring raceway is spherical design, can automatically compensate for axial deviation, but should not bear pure axial load, mostly used in textile machinery.
Cylindrical roller bearings: radial bearing capacity, inner and outer ring can be separated, commonly used in large motor or machine tool spindle.
Tapered roller bearings: can withstand both radial and axial load, the outer ring can be separated, suitable for automotive wheel hubs or rolling mills and other heavy-duty scenarios.
Thrust ball bearings: only bear axial load, low limiting speed, mostly used in machine tool spindle or crane hook.
Spherical roller bearings: performance similar to spherical ball bearings but stronger load carrying capacity, commonly used in paper making machinery or mining equipment.
Other classification
According to the shape of the rolling body: ball bearings (such as deep groove ball bearings), roller bearings (such as cylindrical roller bearings).
According to the direction of force: radial bearings (such as deep groove ball bearings), thrust bearings (such as thrust ball bearings), centripetal thrust bearings (such as angular contact ball bearings).
According to the centring performance: centring bearings (such as centring ball bearings), non-centring bearings (such as deep groove ball bearings).
