7000 AC angular contact ball bearings have raceways in the inner and outer rings that are displaced with respect to each other in the direction of the bearing axis. This means that they are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads.

The axial load carrying capacity of 7000 AC angular contact ball bearings increases with increasing contact angle. The contact angle α is defined as the angle between the line joining the points of contact of the ball and the raceways in the radial plane, along which the load is transmitted from one raceway to another, and a line perpendicular to the bearing axis

7000 AC angular contact ball bearings main application:

(1)single row angular contact ball bearing used in: Machine shaft,high frequency motor,gas turbine, centrifugal separator, small cars front wheel , differential pinions axis.

(2)double row angular contact ball bearing used in:oil pump, ROM. Watts blower , Air compressor , All kinds of transmission , Fuel injection pump , Printing machinery.

The difference between 7000 C and 7000 AC:

C is the Japanese bearing angle code, the contact angle is 15 degrees, it mainly bears radial force and small axial force, and is used for high-precision, high-speed equipment.

AC is the code name of the domestic bearing, the contact angle is 25 degrees, and it is subjected to axial force and radial force.
