Product Description:


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

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: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:How can angular contact be distinguished from the front and back? What are the characteristics of each?
Hello, there is a number on the front, no number on the back
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:What does angle contact back to back mean?
Refers to the installation method, put it is face to face
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 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:What does angular contact ball bearing 70216AC mean?
7--- angular contact ball bearing0--- normal width series2--- diameter series code, which means light series16--- internal diameter code indicating the inner diameter of 16*5=80mmAC--- internal structure code indicating the nominal contact angle of angular contact bearing is 25 degrees
Q:What is the axial load of angular contact ball bearings 7202AC?
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
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.
