Angle contact ball bearing
Angle contact ball bearing can be both radial load and axial load. Can work under at higher speed. Contact Angle is, the greater the axial bearing capacity is higher. High precision and high-speed bearing usually take 15 degrees contact Angle. Under the action of the axial force, contact Angle increases. Single Angle contact ball bearing can only carry axial load in one direction, in radial load, will cause additional axial force. And only limit shaft or shell in a direction of the axial displacement. If quality.the installation, make a pair of bearings, namely the outer ring relatively wide wide end, narrow face the narrow end face. So we can avoid cause additional axial force in both directions, but also in the shaft or shell limit axial clearance range. Angle contact ball bearing outer ring inside the groove because there can be in a horizontal axis relative displacement, so can both radial load and axial load - union load (single Angle contact ball bearing single direction can only carry axial load, so usually paired often adopted installed). Maintains a material has brass, synthetic resins, the bearings form, in accordance with the using conditions and divisional. Angle contact ball bearing are: 7000C type (∝ = 15 °), 7000AC type (∝ = 25 °) and 7000B ∝ = 40 °) (several types. The bearing outer ring in the lock on the mouth, generally can’t be separated from internal and external circle and can withstand radial and axial load and a combination of direction of the axial load. Axial load capacity by contact Angle, contact Angle decision is the ability of axial load high. The bearing can restrict shaft or shell in a direction of the axial displacement.
