AC7000 all ceramic type

The AC7000 series all ceramic angular contact ball bearing is a precision all ceramic version based on the 7000 series AC type (25 ° contact angle). It uses ceramic material as the inner and outer rings+rolling elements, without metal parts participating in rolling friction. It has the characteristics of high temperature resistance, corrosion resistance, non-magnetic insulation, high speed and low resistance. The 25 ° contact angle is suitable for radial load+medium unidirectional axial load composite working conditions, and is the core precision support choice for special working conditions such as high and low temperature, strong corrosion, strong magnetic field, and ultra-high speed.
