Product Description:
Angular contact ball bearing is a rolling bearing that can bear
radial and axial loads at the same time and is suitable for
high-speed operation. The inner and outer ring raceways are at a
certain angle, so that the bearing can bear combined loads. The
contact angle is the core design parameter and determines the axial
load-bearing capacity of the bearing.
Structure and composition
Inner and outer rings: The raceways are at a certain angle, so that
the bearing can bear combined loads.
Rolling element (steel ball): Rolls between the inner and outer
rings to transfer loads.
Retainer (cage): Separates the rolling elements, reduces friction
and wear, and guides the movement of the rolling elements.

Carrying capacity: Angular contact ball bearings have high radial
and axial load capacity, especially when subjected to large axial
loads, its advantages are more obvious. The contact angle of the
bearing determines its load capacity and scope of use.
Contact angle: One of the characteristics of angular contact ball
bearings is that there is a certain contact angle between its ball
and the inner and outer rings, which is usually 15°, 25°, 30°, etc.
The larger the contact angle, the stronger the axial load capacity.
Adapt to high loads: Angular contact ball bearings are usually used
in applications that need to withstand both radial and axial loads.
For example, machine tool spindles, motors, automotive bearings,
etc.
Withstand high speeds: Angular contact ball bearings use spherical
rolling elements, which have relatively low friction resistance and
can operate at higher speeds.
Single row and double row: Single row angular contact ball bearings
usually withstand axial loads in a single direction, while double
row angular contact ball bearings can withstand axial loads in both
directions. Double row types are common in applications that
require higher load capacity.
Preload: Angular contact ball bearings are often preloaded to
improve stiffness and load capacity. This preload can be achieved
through the way the bearing is assembled.
Flexible application: Angular contact ball bearings can be
configured with different angles and structures to adapt to
different working environments and load requirements.
