Remark
NSK 2313K bearing:
NSK 2313K bearings Brand: NSK bearings, bearing type: self-aligning ball bearings, the new models: 2313K, Old Model: 111613, inner diameter: 65 (mm) outer diameter: 140 (mm), thickness: 18 (other information: mm), aligning ball bearings tapered bore (10000K type)
(1) match NSK bearing surface requirements on the bearing mounting portion in the shaft and the housing bore, the surface roughness of the lower, the better the shape and position accuracy, the higher the rigidity of the obtained support. Beneficial to increase the rigidity of these surface subjected to surface hardening treatment. High roughness low hardness Stopper interference with lubrication state repeatedly gently pressed into and exit seat hole, but also conducive to improve the supporting rigidity, if necessary, can be used snap ring similar treatment of the journal .
(2) the use of the the NSK bearing preload method to improve support rigidity can take axial preload on the bearings, short cylindrical roller bearings can be taken to the radial preload method can significantly improve the rigid shaft support, or eliminate NSK bearing clearance, or get a little negative clearance. But speed is not too high, the temperature increase is not a condition, and preferably should also be transferred to the state of the small negative clearance.
