Ball screw bearing is a kind of bearing composed of screw, nut, reversing device and ball for converting rotary motion into linear motion or linear motion into rotary motion. The characteristics of screw ball bearing The ball screw pair has the characteristics of high precision, reversibility and high efficiency.

GQZ mainly sells P4 grade 70C/AC super-precision angular contact ball bearings, which can bear radial load and axial load, and can work at higher speeds. The larger the contact angle, the higher the axial load carrying capacity. High-precision and high-speed bearings usually take a contact angle of 15 degrees. Angular contact ball bearings have: 7000C type (∝=15°), 7000AC type (∝=25°) several types. The lock of the bearing is on the outer ring. Generally, the inner and outer rings cannot be separated, and they can bear combined radial and axial loads and axial loads in one direction. The ability to withstand the axial load is determined by the contact angle. The larger the contact angle, the higher the ability to withstand the axial load.

The design of double row angular contact ball bearings is basically the same as that of single row angular contact ball bearings, but only takes up a smaller axial space. The double row angular contact ball bearing can bear radial load and axial load acting in two directions, it can limit the axial displacement of the shaft or housing in both directions, and the contact angle is 30 degrees. A bearing configuration with higher rigidity can be provided, and it can withstand the overturning moment. We supply following series double row contact ball bearings: 3000 series,3200 series,3300 series,3800 series,3900 series

Single row angular contact ball bearings can only bear axial load in one direction. When this type of bearing is subjected to pure radial load, because the line of action of the rolling element load and the line of action of the radial load are not in the same radial plane, an internal axial component of force is generated, so it must be installed in pairs. Single row angular contact ball bearing structure: 1. Separate angular contact ball bearings The code name of this kind of bearing is S70000. There is no lock on the outer ring raceway, and it can be separated from the inner ring, cage, and ball assembly, so it can be installed separately. These types of miniature bearings with inner diameters less than 10mm are mostly used in gyroscope rotors, micro motors and other devices that have high requirements for dynamic balance, noise, vibration, and stability. 2. Non-separable angular contact ball bearings The ring channel of this type of bearing has a lock, so the two rings cannot be separated. There are three types according to the contact angle: ①Contact angle α=40°, suitable for bearing larger axial load; ②Contact angle α=25°, mostly used for precision spindle bearings; ③The contact angle α=15°, which is mostly used for large-sized precision bearings.
