Sizing Shock Guard
- ・Select an appropriate model for your application.
- ・Select a series to show the selection results and a method to specify the trip torque.
- ・Enter the specifications and click the Select model button.
STEP1 Series selection
Select a series to show the selection results
*Click here for the features of each series.
*Click here for the selection guide for the overload protection devices.
STEP2 Entering the sizing conditions
・Please use “.” for the decimal point and not “,” as the calculation error will occur.
Select a method to specify the trip torque from the following 3 cases
1.When you already know the trip torque
Determine the torque limit which should not be exceeded based on the strength, load, and other conditions of the machine/equipment and specify the value as the trip torque.

In the same series, the model with the minimum specifications that satisfy the conditions is selected.
2.When you determine the torque from the transmission power and rotation speed
Calculate the rated torque from the rotation speed of the shaft to which the Shock Guard will be mounted and the rated output, and multiply it by the service factor according to the usage conditions shown in Table 1. Specify the result as the trip torqu
