6.3.1. Bearing Load
6.3.1.1. Attaching the Load
l The load must be attached to the rotor flange using the threaded mounting holes in the rotor. All of
the bolts should be used, and they should be tightened to prevent slippage.
6.3.1.2. Bearing Load
l The Motor uses a heavy duty bearing that can support most loads directly.
Table 6-1 : Maximum Bearing Load (YS Series)
YS2005 YS2020 YS3008 YS3040 YS4080 YS5120 YS5240
Axial Load Capacity (N) 3 700 4 500 9 500 19 600
Moment Load Capacity (N·m) 60 80 160 400
Distance between Rotor Surface
and Bearing Center* (mm)
26.0 46.5 25.5 52.5 54.0 58.5
* Use these values when calculating the moment load.
Refer to “4.1. Motor Specification” for the details.
Caution : When vibratory axial load is applied, the equivalent allowable load of the Motor
shall be less than 2~3 times of the vibratory load.
