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:

- aircraft engine spindle
- high frequency motor
- printing machinery
- air compressor
- gas turbine
- jet engines

- 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 roller of angular contact ball bearings is ball, because it is a point contact (different from roller bearing line contact), so it can provide higher speed, smaller heating quantity and higher rotation precision. In some high speed spindle applications, ceramic ball hybrid bearings will also be used. Compared with the traditional steel ball, the characteristics of ceramic ball materials endow the ceramic ball bearings with high rigidity, high speed, high temperature resistance and long service life, so as to meet the customers' demand for machine tool bearing products. (flight five Rui reminded you, at present, the mainland ceramic ball mixed bearings spot less, in your choice of such imported bearings, you need to pay attention to delivery time).On the contact angle of angular contact ball bearings, 15 popular and the contact angle of 25 speed; high performance usually contact angle of 15, while the axial contact angle of 25 with high bearing capacity. Due to the effect of preload contact application of ball bearings for precision angle is very large, such as high load capacity, high rigidity of the occasion, will generally choose bearing pre medium or heavy load; and for some applications of high speed and high precision, in the early selection of imported bearings, need to pay attention to choose the appropriate pre load. Pre load is generally divided into light, medium, heavy three kinds, generally light preload is more common. In order to facilitate the use of customers, the general will have universal matching, precision angular contact ball bearings. This type of imported bearings eliminates the customer's preload adjustment, thus saving installation time.
- 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?
- Angular contact bearings common suffix has AC, C and B, AC said nominal contact angle a is 25 degrees, C is 15 degrees, B is 40 degrees.
- 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:What does angular contact ball bearing 70216AC mean?
- Name = General rolling bearing type code No.Standard = excerpt from GB/T 272-1993-----------------------------------------------------------Bearing type = angle contact ball bearingCode =7The original code name is =6Bearing type = angle contact ball bearingDimension series code = (0) 2After two, 16, bearing nominal diameter 16 * 5=80mmName = internal structure codeStandard = excerpt from GB/T 272-1993
- 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.
- Q:Is there a way to calculate the axial force of angular contact ball bearings?
- The rated axial dynamic load of the bearing is: 4300N. Axial force can be calculated by formula. Please consult the professional manual!
