by:JNSN     2021-12-11
Measuring speed of cylindrical roller bearings for motors For single-row cylindrical roller bearings with an inner diameter of ≤60mm, the set speed is 1800r/min; for single-row cylindrical roller bearings with an inner diameter of 65mm~120mm, the set speed is 900r/min. 6.3.2 Applicable Scope The external dimensions conform to GB/T283-2007 regulations N type, NU type, NJ type and NF type, diameter series 2, 3, nominal inner diameter 15mm~120mm, radial clearance conforms to GB/T4604—— Cylindrical roller bearings with zero clearance specified in 2006. 6.3.3 Measurement values u200bu200bFor cylindrical roller bearings with an inner diameter of 15mm~60mm, the vibration (velocity) of a single bearing of different groups should meet the requirements of Table 31. For cylindrical roller bearings with an inner diameter of 65mm~120mm, the vibration (speed) of a single bearing of different groups should meet the requirements of Table 32. Angular contact ball bearing vibration and spherical roller bearing vibration can be compared to deep groove ball bearings, cylindrical roller bearings or according to user requirements, the specific speed and vibration value requirements should be indicated when ordering.
