Radial bearings are rolling bearings mainly used to withstand radial loads, with nominal contact angles ranging from 0 ° to 45 °
Basic classification
Radial contact bearing: with a nominal contact angle of 0 °, typically represented by deep groove ball bearings, suitable for high-speed scenarios but with limited axial load-bearing capacity
Angular contact radial bearing: with a contact angle of 0 ° to 45 °, it can withstand both radial and axial loads simultaneously and needs to be installed in pairs to counteract bidirectional axial forces
Structural characteristics
Rolling element types: ball bearings (point contact, low friction) and roller bearings (line contact, high load capacity)
Installation methods: including back-to-back (high rigidity), face-to-face (convergent contact angle), and co directional arrangement (load sharing), requiring pre tightening to eliminate clearance
Application scenarios
Deep groove ball bearings: high-speed and light load scenarios such as motor spindles and pulleys
Conical roller bearings: heavy-duty environments such as automotive wheel hubs and machine tool spindles
Self aligning bearings: compensating for axial deviation, used in papermaking machinery, vibrating screens, etc
