Widely used Angular Contact Ball Bearing 71952AC / 71956AC /
719/530AC / 72948AC / 72976AC
1) Single row and combined angular contact ball bearing
The more contact angle is, the larger axial load bearing capacity
is,the smaller contact surface is,themuch more convenient high
speed rotary is.
Pretension is made on angular contact ball bearing to increase
rididity and accuracy of bearing.
This bearing creates axial thrust load when being forced by radial
load,thus it is configured(or combined) face to face or back to
2) Double row angular contact ball bearing
Double row angular contact ball bearing can be subinitted radial
and acial louding limit speed is quite high, it is non-separated
type of bearing has high rigid can be submitted doubk direetion of
axial load,the bearing could apply with the four row cylindrical
bearing together to limit the working roll to move in axial
diretion the double row angular contact ball bearing could apply
with other bearings as a position bearing.
3) Four point contact ball bearing
Standard structure is that its inner ring is equally divided in
axial direction,which is applicable to axial load or combined
load,among which acial load is major composition.
Single bearing can bear double row axial load and certain extent
radial load.According to different direction of axial load,ring and
sphere always contact at two points of linear
Angular contact ball bearings: 7000C-type (α = 15 °), 7000AC-type
(α = 25 °) and 7000B (α = 40 °) of several types. The kinds of
bearings in the outer ring lock port, the general separation of
inside and outside the ring can not be combined radial and axial
load and axial load in one direction. Axial load capacity of the decision by the contact angle, contact
angle is greater, the ability to withstand high axial loads. This
kind of bearing shaft or housing to limit axial displacement in one
