Characteristics Of Thrust Ball Bearing

Thrust Ball Bearing

It is a separable bearing with a contact angle of 90 °, which can be installed separately and can only bear axial load. The limit speed is low. The Thrust Ball Bearing steel ball is squeezed to the outside of the raceway with centrifugal force, which is easy to scratch, but it is not suitable for high-speed operation.

One way bearing can bear one-way axial load, and two-way bearing can bear two-way axial load. Thrust Ball Bearing The thrust ball bearing with spherical race has self-aligning performance, which can eliminate the influence of installation error.

Characteristics of angular contact ball bearings

Angular contact ball bearing, Thrust Ball Bearing namely radial thrust ball bearing, can be loaded with more steel balls, its radial bearing capacity is greater than that of ordinary ball bearing, and can also bear large axial load or pure axial load at the same time.

Its allowable working speed is similar to that of deep groove ball bearing and its support rigidity is stronger, but it requires accurate installation and is very sensitive to axis misalignment error, Generally, it does not need to bear the radial load alone, but it must bring additional axial load while bearing the radial load. This kind of bearing has many variants and is widely used.

It is often made into three series with 15 °, 25 ° and 40 ° contact angles. The larger the contact angle is, the higher its axial load capacity is. However, it is appropriate to use a small contact angle at high speed. Most of these bearings are used in pairs for small-span rigid double support shafts or precision spindles. When in use, the clearance should be carefully adjusted. By changing the axial distance between the inner and outer rings of the bearing, the internal clearance of the bearing can be adjusted.

At the same time, several sets of bearings can be installed in parallel and given a certain pre interference, which can improve the rigidity of the bearing system. A single bearing of this type can only bear the axial load in one direction. Thrust Ball Bearing At the same time, other bearings need to be configured to offset their additional axial forces.

When installed in pairs,

their additional axial forces offset each other, and they can bear the axial load of two forces upward, and have strong axial limit capacity in two directions, Generally, two sets of bearings are installed in pairs, with their outer ring wide end face opposite (back-to-back) or narrow end face opposite (face-to-face), in which the rigidity of the back-to-back installation bearing system.

In order to facilitate installation in pairs or groups, some bearing factories supply bearings in pairs, three sets in groups and four sets in groups. In this way, the processing consistency of the supplied bearings in the same batch is good, the load is borne more evenly during use, and the additional axial forces offset each other more thoroughly.

This type of bearing

can be divided into two types: separated type and non separable type. The separated type bearing is used when the installation conditions are limited and the outer ring or inner ring is required to be removed from the whole set of bearings for separate installation. Because the separated type angular contact ball bearing is widely used in magneto, it is also called magneto bearing. In this type of bearing, the locking port is on the inner ring, which can be adapted to higher speed.

Most of these bearings are used in pairs for small-span rigid double support shafts or precision spindles. When in use, the clearance should be carefully adjusted. By changing the axial distance between the inner and outer rings of the bearing, the internal clearance of the bearing can be adjusted. At the same time, several sets of bearings can be installed in parallel and given a certain pre interference, which can improve the rigidity of the bearing system.
