High Speed Angular Contact Ball Bearing 7326BM Chrome Steel Bearing
Single Row Angular Contact Ball Bearings always are mounted in opposition to another bearing of
same type, they offer high mounting stiffness, especially when pre-loaded.
Design Attributes
Withstand combined loads with predominant axial component
Withstand loads in one direction only.
Accept relatively high speeds of rotation.
Angular Contact Bearing
Like other bearings,angular contact ball bearings are also have lots of structures,single row angular
contact ball
bearings can accommodate radial load and axial load in single direction.While double row angular
contact ball
bearings in DB or DF combination and four-point contact ball bearings can accommodate radial load and axial
load in two directions.Angular contact ball bearings suit high-speed rotation and high-precision
rotation.These bearings are mainly used in the fields like machine tool spindles,high frequency motors,
oil pumps,air compressors,printing machines,etc.For four-point contact ball bearings are mostly used
in the roller-boxes of rolling mills to carry axial load.
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 direction.
1 single row (open type)
70, 72, 73, 718, 719 Series
2 double row (open or sealed)
50, 52, 53, 54 series,
32, 33 series
3 Four-point contact
QJ series
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 back.
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
