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?

No, please adjust the heart with the self-aligning bearing

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

Deep groove ball bearings have less carrying capacity, they mainly bear radial load, and can also bear certain axial load at the same time. The friction coefficient is small and the limit speed is high.Increase the bearing capacity of angular contact bearings can bear radial load and axial load, also can withstand the axial load (pure axial load, can bear a direction generally used in pairs), high speed limit.It can be seen that the two bearings differ mainly in the magnitude and direction of the load.

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

AC is the code for homemade bearings. The contact angle is 25 degrees. It is subjected to axial force and radial forceA for Japan bearing angle code, contact angle of 30 degrees, to bear axial force and radial forceC is the bearing angle code of Japan. The contact angle is 15 degrees. It mainly bears radial force and small axial force. It is used in high precision and high speed equipment

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.

Q:How can angular contact be distinguished from the front and back? What are the characteristics of each?

There is no difference between the front and the back of this bearing.There's something wrong with my answer.

Q:What are the reasons for the use of tapered roller bearings and angular contact ball bearings?

Bearing capacity and the form of motion and load factors are different, the choice of bearings compatibility is determined by theory and practice. Visual interpretation is the role of the two bearings, see the mechanical design manual - bearing chapter

Q:Is there a way to calculate the axial force of angular contact ball bearings?

The rated axial dynamic load of the bearing is: 4300N. Axial force can be calculated by formula. Please consult the professional manual!

Q:What is angular contact ball bearing contact angle?

The contact angle is defined as an imaginary angle betweenA linear element added to a rolling contactAligning and a straight line perpendicular to the axis of rotationThe angle between the imaginary line of the contact between the roll and the raceway and the vertical line of the axis of rotation
