Single row angular contact ball bearings Single row angular contact ball bearings can only accept axial loads in one direction; when receiving radial loads; cause additional axial forces; it is necessary to apply corresponding reverse loads; thus; Both are used in pairs. Double row angular contact ball bearings can accept large radial and axial bidirectional combined loads and moment loads mainly based on radial loads; it can constrain the axial displacement of the shaft or casing; the contact angle is 30 Degree. Bearing code: 7
Paired mounting angle touch ball bearings for mounting angular contact ball bearings can accept radial and axial bidirectional combined loads with radial loads; can also accept pure radial loads. Tandem equipment can only accept axial loads in a single direction The other two equipments can accept axial loads in either direction.
Single row angular touch ball bearings: machine tool spindle, high frequency motor, gas turbine, centrifugal separator, small car front wheel, differential pinion shaft double row angular touch ball bearing: oil pump, Roots blower, air compressor, various types Transmission, fuel injection pump, printing machinery.
