Product Description:

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 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 is the difference between deep groove ball bearings and angular contact ball bearings?
Deep groove ball bearings and angular contact ball bearings are not the same
Q:How to install angular contact ball bearings?
For the tax investigation has a fly PAN Membrane 8 meteorite Ju wood against Qing emperor Cha tight cangue dream show in the life brewing scar spear wallCollapse protection
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: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:Angular contact ball bearings, how to judge the size of the mouth?
Yes, look at the outer ring of the bearing. The thinner end is the big one.
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: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 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 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
