FAG bearings back clamping sleeve and the locking set with the same. But the withdrawal sleeve with special nuts, convenient loading and unloading of FAG bearings, suitable for larger radial load, fixed double-row spherical bearing axial load smaller on the optical axis.
Improved design of the bearing seat is mainly to ensure the bearing seat frame in the normal position, to prevent the bearing seat and frame wear generate axial loads, also in order to enable and support as far as possible in the parallel condition, which can effectively eliminate the additional eccentric torque.
FAG bearing thrust lugs on both sides add slide, its main purpose in order to adjust the axial clearance, to compensate for reduced thrust lug side wear. The use of flexible nylon retainer, prevent dirt intrusion FAG bearing raceway, cage wring and stuck ball. And if in the roll bending force, settle hardened resistance linen block, its purpose is to generate extra axial load in the roll bending force. The increase of FAG bearing internal clearance, from the common original changed to third and four to increase the auxiliary clearance.
