Sepcification:
Angular contact ball bearings can bear radial load and axial load at the same time and also can bear pure axial load. Their ability of axial load is determined by contact angle and is increased with contact angle increasing; speed limit is higher; stiffness is big and can be pre-adjusted. They are applicable to high-speed and high-precision site.
Product application:
- spindle and other high speed precision mechanical spindle
- aircraft engine spindle
- high frequency motor
- printing machinery
- air compressor
- gas turbine
- jet engines
- turbines

- 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:Can angular contact ball bearings be adjustable?
- No, please adjust the heart with the self-aligning bearing
- Q:The difference between ultra high speed angular contact ball bearings and other plain bearings
- The ability to bear the axial force of angular contact ball bearings than ordinary high speed ball bearings, angular contact ball bearing is slightly lower than the ordinary ball bearings of the same type.
- Q:What is angular contact ball bearing contact angle?
- The angle between the imaginary line of the contact between the roll and the raceway and the vertical line of the axis of rotation
- 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: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: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:Angular contact ball bearings, how to judge the size of the mouth?
- Judge the size of the mouth, of course, big mouth is large, that is, the edge of the slope for the side of the big mouth.
- Q:How can angular contact be distinguished from the front and back? What are the characteristics of each?
- Hello, there is a number on the front, no number on the back
- 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.
