EC ELECYLINDER Because the radial cylinder has a linear guide built into the body, radial and moment loads can be applied to the rod.
Radial load acting on the rod
The allowable radial and moment loads must meet the following three conditions.
1. The radial load acting on the rod must not exceed the allowable value.
Mc

EC-RR6
2. The torque (Mc) acting on the rod must not exceed the allowable value.

3. The uniform load acting on the rod must not exceed the allowable value. The uniform load is obtained by the following formula.
Uniform load = Ma · Ka + Mb · Kb + Mc · Kc
