NSK rolled out ply and automatic gear-box sliding bearing identical, the hub that takes sealing ring needle bearing. Because ply and sliding bearing are identical, the oil path that can achieve level of as coequal as sliding bearing above and oil measure control, because this can replace sliding bearing. As automatic gear-box much archives is changed, high speed is changed, miniaturization and the ceaseless development that look of high load capacity quantifies, the norms requirement of sliding bearing is stricter and stricter also. And still appeared to use low viscosity ATF greatly to increase spread burning effect (automatic transmission fluid) , the trend that the lube supply that reduces whole package measures. Accordingly, need those who solve such as to raise bearing to fight the task such as agglomeration sex, the requirement uses swivel design. The takes sealing ring hub that develops this needle bearing uses sealing ring only thick 0.

The Bao Bi of 85mm is designed, thereby the ply with sectional bearing the 3 ～ from before 3.

5mm was reduced 1.

5mm. Optimized the clearance of runner shaft coming back and sealing ring through development notebook sealing ring, the control that because this can realize the bearing interior of level of as coequal as sliding bearing above,oil of be well versed in measures. Additional, still use swivel design, rose to fight agglomeration sex, reduced low rotate the attrition loss of area. The target of NSK is, the takes sealing ring hub that faces automatic transmission case needle bearing achieved year of sale of about 4 billion yen 2010. Additional, this company shows, outside dividing automatic transmission case, in still can mixing the other industry beyond motor vehicle and car, this bearing is used. CNC Milling
