angular contact ball bearing 7008

angular contact ball bearing can support radial load and axial load. Can work at higher speeds. Contact angle decreases, the higher the axial load capacity. High precision and high-speed bearings usually take the contact angle of 15 degrees. In the axial force, the contact angle will increase. Single row angular contact ball bearings can only support axial load in one direction, the bearing radial load, will cause additional axial force. And the shaft or housing can limit the axial displacement in one direction. If pairs of double-install, make a pair bearing the outer ring relative, that is, wide-side end face of wide and narrow side facing narrow end. This can avoid additional axial force, but also in both directions to limit the shaft or housing within the axial clearance.
