Side Loads on Denso motors

[Vikesrock]

My team was discussing how to mount our roller on the front of our robot and the prevailing idea seemed to be to power it with 1 ND motor on each side and use those for the sole mounting of the assembly.

What I was wondering is if the motors will tolerate the side loading this application would cause? The loading will mostly be derived from compressing the balls ~1-1.5". The mechanism should be mostly protected from incursion by other robots and trailers based on it's height and the design of the front of the robot.
