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
-pump

- 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 does angle contact back to back mean?
- Two bearing by webbing webbing. (face is once again thick, thin again)
- 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: 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: Can angular contact ball bearings be adjustable?
- May not。Self-aligning ball bearings and spherical roller bearings are adjustable.
- 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: 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: 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: 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: 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.
