The graph shows how the radial force permitted on the axis decreases as the
turning speed increases. The illustration on the right shows the radial force applied
onto the axis [ Fr ] and distance to the ball bearings.
When using mechanical transmission elements, the end of the motor shaft may be
subject to radial loads.

Note that when installing transmission pulleys or gearboxes, any blow to the shaft reduces
its useful life, of beraings, and may damage the encoder. Therefore, do not hit it for any
reason.
• Make sure that the maximum radial load values at the end of the shaft do not exceed
the permitted values shown in the table 1.
• Exceeding these radial load values increases the vibration of the shaft and shortens the
life of the ball bearings and couplings.
