Contact Ball Bearing Type

The locks of the 7000C type (∝ x 15 degrees), the 7000AC type (∝ x 25 degrees) and the 7000B (∝ s 40 degrees) are on the outer ring, the general inner and outer rings cannot be separated, and can withstand the combined load of radial and axial direction and the axial load in one direction. The ability to withstand axial loads is determined by the contact angle, which is large, and the ability to withstand axial loads is high. This type of bearing can limit the axial displacement of the shaft or housing in one direction.
