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: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:Can angular contact ball bearings be adjustable?
- No, please adjust the heart with the self-aligning bearing
- 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: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 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 and deep groove ball bearings?
- You take a look at two, you know, the angle of contact with a few angles to look at, you know the difference
- 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:Is there a way to calculate the axial force of angular contact ball bearings?
- This is the first response to the landlord, you can count, here introduces the concept of equivalent static load, a static equivalent radial load P0a (subscript 0A), a static equivalent axial load P0a (subscript 0A), and a static safety factor FS, we first check the static C0 7202AC (0 Department of AC, should represent the subscript) is the contact angle is 25 degrees, SKF C0 4800N, personally think that this value is too conservative, according to P0a=2.3*Fr*tg25+Fa (Fr is bearing radial load, axial load bearing is Fa, tg25 is the tangent, contact angle of 25 degrees according to the contact angle vary) and FS (fs=C0/P0) is greater than 1.5, launched: P0a less than 3200N, 1.07Fr+Fa less than 3200N that is to say, add up to force multiplied by the coefficient two component bearings, can not exceed this number. If only the axial force, the axial force is Fr=0, maximum 3200N can finally add a few points, FS safety coefficient is adjusted according to the condition, some places may be less than 1, and the place that cannot be less than 1.5, not less than 3, do not understand, temporarily by not less than 1.5. Also hope to help add master. And then there's the C0. Every brand might have a small difference. Here's SKF. So, if you calculate it in theory, you're going to make it smaller
