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

- 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
- 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.In general, deep groove ball bearings are lubricated with dust cover. Angular contact ball games are generally lubricated with lubricating oil, without dust cover, such as grease lubrication, the effect is poor.
- Q:Can angular contact ball bearings be adjustable?
- You say, of course notHave you seen when you spend RMB Mingbi useful
- 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:What is angular contact ball bearing contact angle?
- Angular contact ball bearings can simultaneously bear axial force and radial force in one direction. The rolling force of upper and lower points of attachment at a certain angle and radial direction. Such bearings are angular contact 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 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: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?
- 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: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
