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.

- 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 are the differences between angular contact bearings and deep groove ball bearings?
- Deep groove ball bearings and angular contact ball bearings with inner and outer diameters and wide dimensions have the same inner ring size and structure, but have different outer ring sizes and structures:1. deep groove ball bearings, outer raceway, both sides of the double shoulder, and angular contact ball bearings generally single shoulder;2. deep groove ball bearings, raceway curvature and angular contact ball is different, the latter is often greater than the former;3. deep groove ball bearings, outer raceway and angular contact ball bearings of different, non central position, the specific value of angular contact ball bearings designed to be considered, and the degree of contact angle related;In terms of use:1. two different purposes, suitable for deep groove ball bearings bear radial force and smaller axial force, axial and radial load and combined load torque, and angular contact ball bearings can withstand axial load, radial load is larger (with different contact angles and loads of different sizes), double matching (with matching mode vary) is two-way can withstand axial load and torque load.2., the limit speed is different, the same size of angular contact ball bearings, the ultimate speed is higher than deep groove ball bearings.With type, size, precision, and so on.
- 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: 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: 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: 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?
- 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?
- 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: Two angular contact ball bearings, the use of clearance problems
- Bearing in pairs need not be adjusted! The bearing is marked with letters!DB: back to backDF: face to faceDT: series connectionSU: single arbitrary combinationDU: any combination of two bearings.There is also a combination of three columns and four columns with letters on each bearing!Among them, when selecting the SU mark bearing, it is necessary to choose the bearings with the most close tolerance of the inner and outer ring diameter together. Clearance adjustment is also relatively easy.It is difficult to pair the bearings by adjusting the two common bearings together by adjusting the experience. It is best not to try in such a strict place!
- 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!
