High Speed Angular Contact Bearing With Low Noise For Food
Machinery
1. Product Description
High Speed Angular Contact Bearing With Low Noise For Food
Machinery contains three froms of SRACBB,DRACBB,FPCBB. It can bear the radial and axial load at the
same time, because in the radial load will cause 100 internal axial
force, so it should be installed and used, its configuration has
"back to back", "face to face", "string coupling" and
"multi-coupling", and through pre-tightening can improve the
stiffness of the spindle.The contact angles of such bearings are
15°, 25° and 40°, among which the B7000CY high-precision angular
contact ball bearing with contact Angle of 15° is a special bearing
specially designed for the spindle of high-speed grinding machine.
In addition to the internal structure design changes, the ring and
rolling body are made of high-quality electroslag bearing steel

High Speed Angular Contact Bearing With Low Noise For Food
Machinery are widely used in food machinery,printing machinery
,machine tool,chemical machinery,transmission,motor etc.
4. Advantages
This type of angular contact bearing has high rotation precision
and limit speed, low friction, low temperature rise.Double row
angular contact ball bearings are generally made of nylon cage or
brass solid cage.Compared with single row angular contact ball
bearing, double row angular contact ball bearing has better
rigidity and can withstand overturning moment.The bearings are
non-separated.It is especially suitable for applications with high
rigidity requirements.Widely used in the front wheel hub of cars
(some models also use the same size double row tapered roller
bearings).
