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 are the reasons for the use of tapered roller bearings and angular contact ball bearings?
- Take the radial load and axial load of the shaft evenly, pay attention to the normal and reverse loading, or the axial direction can not be fixed.
- Q:Can angular contact ball bearings be adjustable?
- May not。Self-aligning ball bearings and spherical roller bearings are adjustable.
- 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: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: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?
- 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:Angular contact ball bearings, how to judge the size of the mouth?
- Angular contact bearing on both sides of the outer ring thickness is not the same thin, over there is big mouth
- 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 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 does angle contact back to back mean?
- Angular contact ball bearings are interesting bearings. Divided the face and back. And others, ha ha.See young lovers not.Happy time, hold together KISS, KISS is certainly the mouth to mouth, face to face, we use the word FACE to English it said about this status. ?When angry, who also ignore, two people are turned away, back to back, this is back to back, we use the word BACK to English it said about this status.Whether back-to-back or face-to-face, it must be by a movement of two or more than two people to complete (a person, it had to go in front of the mirror), we have two people to do that, we use DOUBLE to represent these two individuals.DOUBLE: twoFACE: faceBACK: backSee the above three words, no, very clever, angular contact ball bearings also say so.On behalf of the two sets of bearings with DOUBLE - is a "D",Using FACE for face to face, shorthand is a "F"",BACK - back to back, is a "B".OK, now came out in angular contact ball bearings inside the two face is bearing code BF, two back-to-back bearing is DB.
