NSK bearings tolerance refers to the bearing parts processing after the dimension, form and position tolerances and the rotating precision of NSK bearings products.
The tolerance of NSK bearings mainly divides into the centripetal bearing tolerance taper roller bearings, thrust bearing tolerance and tolerance.
About high speed and high precision rotation mechanism, ordinary class 4, grade 2 bearing, for example, high precision gear grinding machine, precision coordinate of spindle bearing bed, aviation, high-speed photography main bearing, etc.
About half of the medium speed and rotating precision request is not high transmission installation, choose a level 0 bearings, into the gearbox, the feed box of ordinary machine tool, automobiles, tractors, etc.
About the installation, about the high rotating speed and high precision request that the rotation of the class using 6, 5 bearing, for example, the common machine tool spindle bearing, its front bearing ordinary USES level 5.
Common use level 6, after bearing, precision machine tool spindle bearing with level 5, precision instrument, instrument bearing used more tolerance of 4 class above.
Anyhow, the choice of bearing tolerance, depending on working condition and to use the request.
