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: 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 does angle contact back to back mean?
Refers to the installation method, put it is face to face
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: The difference between ultra high speed angular contact ball bearings and other plain bearings
Yue bearing features:1. low heating and high speed.X products 2. using heat and friction wear is made of SHX material production, to realize high speed and long life.3., according to different uses, established a different contact angle and ball material specifications of the powerful lineup.4., with wide sealing ring, compared with open bearings, grease life increased to 1.7 times, to achieve a long life.Compared with plain bearings, plain bearings only play the role of reducing the friction coefficient in the power transmission process and keeping the center of the shaft fixed when the parts on the shaft produce relative motion with each other. Low wear resistance, short life, performance is far less than ultra-high speed angular contact ball bearings, but considering the price, the average bearing price may be lower.
Q: Can angular contact ball bearings be adjustable?
No, please adjust the heart with the self-aligning bearing
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: 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?
There is no difference between the front and the back of this bearing.There's something wrong with my answer.
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: Is there a way to calculate the axial force of angular contact ball bearings?
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
