Q:The difference between ultra high speed angular contact ball bearings and other plain bearings

The roller of angular contact ball bearings is ball, because it is a point contact (different from roller bearing line contact), so it can provide higher speed, smaller heating quantity and higher rotation precision. In some high speed spindle applications, ceramic ball hybrid bearings will also be used. Compared with the traditional steel ball, the characteristics of ceramic ball materials endow the ceramic ball bearings with high rigidity, high speed, high temperature resistance and long service life, so as to meet the customers' demand for machine tool bearing products. (flight five Rui reminded you, at present, the mainland ceramic ball mixed bearings spot less, in your choice of such imported bearings, you need to pay attention to delivery time).On the contact angle of angular contact ball bearings, 15 popular and the contact angle of 25 speed; high performance usually contact angle of 15, while the axial contact angle of 25 with high bearing capacity. Due to the effect of preload contact application of ball bearings for precision angle is very large, such as high load capacity, high rigidity of the occasion, will generally choose bearing pre medium or heavy load; and for some applications of high speed and high precision, in the early selection of imported bearings, need to pay attention to choose the appropriate pre load. Pre load is generally divided into light, medium, heavy three kinds, generally light preload is more common. In order to facilitate the use of customers, the general will have universal matching, precision angular contact ball bearings. This type of imported bearings eliminates the customer's preload adjustment, thus saving installation time.

Q:Can angular contact ball bearings be adjustable?

May not。Self-aligning ball bearings and spherical roller bearings are adjustable.

Q:What is the difference between deep groove ball bearings and angular contact ball bearings?

Deep groove ball bearings and angular contact ball bearings are not the same

Q:What are the differences between angular contact bearings AC and A and C?

Angular contact bearings common suffix has AC, C and B, AC said nominal contact angle a is 25 degrees, C is 15 degrees, B is 40 degrees.

Q:Do angular contact ball bearings come with a sealing cap?

Angular contact ball bearings generally have no dust caps or seals. You can design and install an oil seal or something like that.In general, deep groove ball bearings are lubricated with dust cover. Angular contact ball games are generally lubricated with lubricating oil, without dust cover, such as grease lubrication, the effect is poor.

Q:How to install angular contact ball bearings?

The installation of angular contact ball bearings is more complicated than deep groove ball bearings. It is mostly installed in pairs, and preload is necessary. Well installed, can make the host work accuracy, bearing life greatly improved; otherwise, not only the accuracy can not meet the requirements, the life will be affected.The installation form of angular contact ball bearings, a series of face to face and back to back, three. (two back-to-back wide end bearing relative) installation, bearing contact angle line along the axis of rotation diffusion direction, bearing angle can increase the radial and axial rigidity, maximum deformation resistance; face to face (two relatively narrow end bearing) installation, bearing contact angle of the rotary axis line towards the direction of its convergence. To the point of less rigidity. Because of the inner ring of the bearing outer ring out, when pressing the outer ring two bearing together, the original gap ring is eliminated, can increase the bearing preload; tandem arrangement (two wide end bearing in one direction) when installing the bearing contact angle and parallel lines in the same direction, the two share the same bearing the direction of the work load. However, in order to ensure the axial stability of the installation, the two pairs of bearings arranged in series must be installed opposite the ends of the shaft in order to ensure the axial stability of the installation.

Q:Two angular contact ball bearings, the use of clearance problems

The installation form is DB, and the inner ring preload is adjusted. For example, by adjusting the nut of the lock inner ring, tighten the force adjustment. Generally selected bearings, manufacturers have been conscious of the inner ring and outer ring thickness is not the same, that is, as long as locking the inner ring, the force is the factory set the amount of preload.

Q:Angular contact ball bearings, how to judge the size of the mouth?

Angular contact bearing on both sides of the outer ring thickness is not the same thin, over there is big mouth

Q:What are the differences between angular contact bearings and deep groove ball bearings?

You take a look at two, you know, the angle of contact with a few angles to look at, you know the difference

Q:What does angle contact back to back mean?

Refers to the installation method, put it is face to face
