Product Description:

Angular Contact Ball Bearing

Description:

1,Single row and combined angular contact ball bearing 

Standard contact angle is 150,250 and 400 respectively configuring in post position with code "C","AC" and "B".The more contact angle is, the larger axial load bearing capacity is, the smaller contact surface is, the much more convenient high speed rotary is.Pretension is made on angular contact ball bearing to increase rigidity and accuracy of bearing.This bearing creates axial thrust load when being forced by radial load, thus it is configured (or combined) face to face or back to back.

 

2,Double row angular contact ball bearing

When configured back to back, bearings are composed of inner ring and outer ring only.

 

3,Four ponit contact ball bearing

Standard structure is that its inner ring is equally divided in axial direction, which is applicable to axial load or combined load, among which axial load is major composition.Single bearing can bear double row axial load and certain extent radial load. According to different direction of axial load, ring and sphere always contact at two points of linear line.When four point contact bearing is used, please contact with ZWA for analysis of operating conditions including bearing load.

Q:What is angular contact ball bearing contact angle?
Angular contact ball bearings can simultaneously bear axial force and radial force in one direction. The rolling force of upper and lower points of attachment at a certain angle and radial direction. Such bearings are angular contact bearings.
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?
The front outer ring is wide and the outer back is narrow.
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 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: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 reasons for the use of tapered roller bearings and angular contact ball bearings?
Selection of bearings in accordance with the theory and practice of judgment, that is, bearing capacity and the form of movement and load factors are different. That is, the role of the two bearings
Q:What is the axial load of angular contact ball bearings 7202AC?
The ball bearing theory is not subjected to axial force, but it will be subjected to slight axial force in practical application because it has certain centering action and will return to its original position after the axial force disappearsThe size of the axial force to have contact with the actual working environment, stress condition of ball bearings after the axial force is equivalent to the contact angle becomes similar to the angular contact ball bearing, the axial force and clearance of bearing, the ditch radius have a great relationship.Especially the clearance, the greater the clearance, the steel ball in the axial position of the greater the scope of movement, that is, the greater the axial clearance, the axial force can also be greater, but the clearance can not be blindly large.In short, we can tell you that the axial force is much smaller than the radial force. As for how to calculate it, the contact angle can not be predicted, so there is no way to knowMore exciting questions, please click on the account login electromechanical Online - Baidu cooperation know platform
Q:Two angular contact ball bearings, the use of clearance problems
Bearing in pairs need not be adjusted! The bearing is marked with letters!DB: back to backDF: face to faceDT: series connectionSU: single arbitrary combinationDU: any combination of two bearings.There is also a combination of three columns and four columns with letters on each bearing!Among them, when selecting the SU mark bearing, it is necessary to choose the bearings with the most close tolerance of the inner and outer ring diameter together. Clearance adjustment is also relatively easy.It is difficult to pair the bearings by adjusting the two common bearings together by adjusting the experience. It is best not to try in such a strict place!
