Angular contact ball bearing is a bearing, it can support radial and axial loads. Able to work at higher speeds. The contact angle, the higher the axial load carrying capacity. High-precision and high-speed bearings usually take the contact angle of 15 degrees. In the axial force, the contact angle will increase. Angular contact ball bearings can support radial and axial loads. Able to work at higher speeds. The contact angle, the higher Thin section bearings the axial load carrying capacity. High-precision and high-speed bearings usually take the contact angle of 15 degrees.
In the axial force, the contact angle will increase. Single row angular contact ball bearings can withstand axial load in one direction, while the radial load, will cause additional axial force. And the only limit axial displacement in one direction shaft or housing. If paired installation, so that one pair of bearing outer ring relative to that wide side face of wide and narrow side facing the narrow end. This can avoid additional axial force, and the shaft or housing to limit axial clearance within the range in both directions.
Angular contact ball bearing raceway for its inner and outer rings relative displacement on the horizontal axis, so it can support radial load and axial load - combined load mobile crane bearing (single row angular contact ball bearings can withstand axial load in one direction, So often adopted installed in pairs).
Cage made of brass, synthetic resins, etc., depending on the bearing forms, and application conditions.
Angular contact ball bearings: 7000C-type (α = 15 °), 7000AC type (α = 25 °) and 7000B (α = 40 °) of several types. This kind of bearing outer ring of locking in the general inner and outer rings can not be separated, can withstand radial and axial joint load and axial load in one direction. Axial load capacity from the contact angle, the contact angle is large, the ability to withstand high axial loads. This kind of bearing can limit the axial displacement in one direction shaft or housing.
The main purpose
Single row angular contact ball bearings: machine cross roller bearings tool spindles, high frequency motors, gas turbines, centrifuges, small car front wheel, differential pinion shaft
Double row angular contact ball bearings: pump, blower, air compressor, various types of transmission, fuel injection pumps, printing machinery
Installation Tips
High-speed precision angular contact ball bearings, mainly used for high-speed rotating load lighter occasions, requiring high precision bearings, high speed, low vibration and low temperature rise certain life. Often high-speed spindle bearing installed in pairs, the inner surface grinder spindle speed key component parts.
