Spindle bearing7020AC 7020ACDGA 7020 ctp4 single row angular contact ball bearing 100*150*24mm
Product Description
single row angular contact ball bearings can accommodate axial loads in one direction only. This type of bearing is typically adjusted against a second bearing. Their bearing rings have an upper and a lower shoulder and are non-separable. They have features as below: (1)High load carrying capacity ;(2)Good running properties;(3)Easy mounting of universally matchable bearings

Working principle:
It uses axially asymmetric races. An axial load passes in a straight line through the bearing, whereas a radial load takes an oblique path that tends to want to separate the races axially. So the angle of contact on the inner race is the same as that on the outer race. Angular contact bearings better support "combined loads" (loading in both the radial and axial directions) and the contact angle of the bearing should be matched to the relative proportions of each. The larger the contact angle (typically in the range 10 to 45 degrees), the higher the axial load supported, but the lower the radial load.
Angular contact ball bearing include:
1) Single row angular contact ball bearing
2) Matched angular contact ball bearing
3) Double row angular contact ball bearing
4) Four-point contact ball bearing
Angular contact ball bearings features :
1) Load capacities are higher than deep groove ball bearings of same dimensions;
2) Used for bearing radial-axial combined loads or pure thrust loads;
3) Low operating friction and high limiting speed.
