What are the types of ball bearing

The ball bearing is a rolling bearing, the spherical alloy steel ball middle installed inside thesteel ring and the outer ring, by the rolling way to reduce friction during power transmissionand improve the transmission efficiency of the mechanical power. Ball bearings can bearlarger load, is common in light industrial machinery. What are the types of ball bearings?Types of ball bearing with single ball bearing, double ball bearing, radial ball bearings andthrust angular contact ball bearing.

Single ball bearing is the improvement on the traditional seal bearing. Between the rotor and the stator with its ball for lubrication, and with lubricating oil. It overcomes the defects of short service life of the bearing oil seal, unstable operation problem, and rising costsare extremely limited. Single ball bearing absorbs advantages of seal bearing and doubleball bearing. The service life of the bearing to ascend to 40000 hours, after joining theball, running noise increased, but still less than double ball bearing.

Double ball bearing belongs to the bearing relatively high-grade. The bearings are tiny ballaround the axis, when the fan page or axis rotates, the steel ball is followed to rotate.Because it is a sphere, so the friction force is small, and don't have a problem with oil.Double ball fan has the advantages of long service life, hours at about 50000 ~100000;anti aging performance is good, suitable for high speed fan. Double ball bearing fault ishigh in manufacturing cost, and at the same speed level (maximum noise because of friction point of ball bearing is increased by 2 times).

Centripetal thrust ball bearings are also translated into angular contact ball bearing. At the same time can bear radial load and axial load for angular contact ball bearing. Can work at a higher speed. The larger the contact angle, the higher the axial bearing capacity. High precision and high speed bearings usually take 15 degrees contact angle. Under the action of axial force, contact angle increases. The axial load of single row angular contact ball bearings can withstand a direction, in radial load, will cause additional axial force. The axial displacement of the bearing can limit shaft or shell in one direction. If the duplex mounting, so that a pair of bearing outer ring relatively, namely wide end of the wide end,the narrow end face with narrow end. So to avoid the additional axial force, but also in two directions so that the shaft or housing restrictions in the axial clearance range.
