NTN bearing inner ring of the assembly process

1. Bearing shaft shoulder fixed NTN bearing inner ring axial fixation rely on the shoulder and interference. Applicable to both ends fixed supporting structure. Simple structure, small outer profile size. 2. By bearing fixed bearing inner ring by the shoulder and lock nut axial fixation. Affordable small two-way axial load. Axial structure size is small. 3. Bearing lock nut fixed NTN bearing inner ring by the shoulder and lock nut axial fixation. And a lock washer with locking, safe and reliable, suitable for high speed and overloaded. 4. Bearing the face of thrust washer fixed NTN bearing inner ring by the shoulder and shaft end ring axial fixation. Shaft end ring on the shaft end with screws. Set screw should be locking device. Should not be applicable to the shaft end cutting thread or space limit. 5. Bearing sleeve is fixed on fixed set of inner hole of the radial dimension is compressed and clamped on the shaft, to realize the bearing inner ring axial fixation. 6. Bearing the withdrawal of fixed withdrawal sets of clamping way and set the same. But withdrawal sets with special nut, NTN bearing loading and unloading of convenient, suitable for radial load is bigger, smaller double row spherical bearing axial load on the optical axis fixed. Bearing assembly process of the grinding parts after inspection qualified people assemble libraries. If the production organization is proper. Separation between parts may also directly into the assembly set, bearing without warehouse save, NTN bearing to reduce production cycle. Warehouse keeper should not only keep the bearing assembly parts. Knowledge of ring rolling into the size tolerance, rolling body size tolerance. Make statistics, parts tolerance order list and organize complementary parts, to assembly or set of process. For small batch production. Especially in the rolling element and raceway size large, bearing group is often adopted in the production of grinding a ring and sorting the ring size tolerance, again with rolling body size deviation, another ring for bearing raceway grinding size deviation range, in order to obtain a higher set of rate. Under normal circumstances, the final outer raceway near outer ring grinding machining process finally, custom-made tolerance on the outer ring is better.
