How to distinguish bearing types?

Bearing industry can be roughly divided into two categories, and each category contains several subclasses. Let's talk about how to distinguish bearing types.

0 1 angular contact ball bearing, there is a contact angle between the ring and the ball. The standard contact angles are15, 30 and 40. The greater the contact angle, the greater the axial bearing capacity. The smaller the contact angle, the better the high-speed rotation.

Deep groove ball bearing and deep groove ball bearing are the most representative rolling bearings. This kind of bearing has the lowest friction coefficient. It mainly bears radial load and can also bear certain axial load.

Self-aligning ball bearing, double-row steel ball and outer ring raceway are inner spherical surfaces, and tapered hole bearing can be easily installed on the shaft through fasteners, mainly to bear radial load.

Sliding bearing, sliding bearing has no inner ring and outer ring, no rolling body, and is usually made of wear-resistant materials. Usually used for low speed, light load and lubrication, as well as mechanical rotation that is difficult to maintain.
