High Precision Angular Contact NTN Ball Bearing QJ Series With Less
Detailed Product Description
Angular contact ball bearing can withstand radial load and axial
load simultaneously, as well as the pure axle loads. They have
higher limit speed. High precision and high speed bearings usually
take 15 degrees contact Angle. The contact angle decide the
capacity of axial load. Retainers are made of brass, synthetic
resins or others subject to individual bearing features and
Single-row angular contact ball bearings can accommodate axial load
in one direction, if enduring radial load, it will raise additional
axial force. And only limited axial displacement of the shaft or
housing in one direction. The contact angle of angular contact ball
bearings is 40, so you can afford a large axial load. Design of
angular contact ball bearing is non-separable, shoulder height on
both sides of the inners and outer rings are different. In order to
increase the bearing load capacity, lower one side of the shoulder,
so that the bearing can be mounted into more balls.
Pairs of angular contact ball bearings can accommodate radial loads
as the principal combined radial and axial bi-directional load or
under purely radial load. Tandem configuration can only take a
single direction axial load, other configurations can be subjected
to either direction of axial loads. This type of bearings are
generally submitted by manufacturers combine matching users,
pre-loading interference after installation, rings and balls of
steel in the axial pre-load state, thus improving the supporting
stiffness and running accuracy of bearing the whole group as a
(1) have raceways in the inner and outer rings that are displaced
with respect to eachother in direction of thebearingaxis.
(2) This means that they are designed to accommodate combined
loads, i.e, Simultaneously acting radial and axial loads.
(3) The axial load carrying capacity of increase with increasing
(4) The contact angle is defined as the angle between the line
joining the points of contact of the ball and the raceways in the
radial plane, transmitted from one raceway to another.And a line
perpendicular to the bearing axis.
1.Load capacities are higher than deep groove ballbearingof same dimensions.
2.Used forbearingradial-axial combined loads or pure thrust loads.
