3.3.2 Allowable Radial and Thrust Loads
The following table shows the allowable loads applied to the SGMVH servomotor shaft end.
Design the mechanical system so radial and thrust loads applied to the servomotor shaft end during operation
falls within the ranges shown in the following table.
Note that even when using a servomotor below the allowable radial load, the following imbalance or the loads
may damage the bearings.
• The imbalance of parts that are connected to the shaft end
• Rotating loads generated by unmatched concentricity, when the bearing is attached to the extended shaft
end.
(1) 1500 min
-1
Series
Note: Allowable radial and thrust loads shown above are the maximum values that could be
applied to the shaft end from motor torque or other loads.
(2) 800 min
-1
Series
Note: Allowable radial and thrust loads shown above are the maximum values that could be
applied to the shaft end from motor torque or other loads.
