Product Description:

Specification of Textile Machinery bearings:

Bearings for textile machinery are generally used under severe working conditions that require long service life, heavy loading capacity, high rotation speed, low noise , and stable operations, the bearings for textile machinery independently developed by CNBM have excellent performance and have already been adopted by mainly domestic manufactures of textile machines. Special bearings manufactured by CNBM for airflow textile machines can run steadily at a very high speed with small amplitude, low noise, and long service life. Top roller bearings for textile machines have the characteristics of strong self-aligning function, supreme dust-proof performance, heavy loading capacity, stable operation, and long service life.

Q:What are the differences between angular contact bearings and deep groove ball bearings?
The difference between deep groove bearings with the angular contact bearings in the structure is: deep groove bearings and rolling contact rail check section view on the parallel with the axis, the angular contact bearing rail has an open angle in one direction, and the axis or axis of the vertical line and an alpha angle. As shown. No. 6 bearings mainly bear radial force, bearing No. 7 can bear radial force and axial force.
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: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:Two angular contact ball bearings, the use of clearance problems
No adjustment required,DB: back to backDF: face to faceDT: series connectionSU: single arbitrary combinationDU: any combination of two bearings.
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: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:Can angular contact ball bearings be adjustable?
You say, of course notHave you seen when you spend RMB Mingbi useful
Q:How many angles are there in angular contact ball bearings? How many degrees are they?
A stands for 30 degrees, A5 stands for 25 degrees, B stands for 40 degrees, and C stands for 15 degreesThe new Seiko NSK serves you!
Q:What does angular contact ball bearing 70216AC mean?
7--- angular contact ball bearing0--- normal width series2--- diameter series code, which means light series16--- internal diameter code indicating the inner diameter of 16*5=80mmAC--- internal structure code indicating the nominal contact angle of angular contact bearing is 25 degrees
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.
