sizing Power-Lock

We will select the appropriate Power-Lock based on your specified conditions.

When selecting "Select from shaft diameter," select the model number that matches the specified shaft diameter and determine whether it satisfies the specified torque.
When selecting from torque, select the model number with the smallest shaft diameter that satisfies the specified torque.
In either case, the shaft and boss surface pressure tolerance is determined, the minimum outer hub diameter required, and the maximum hollow shaft inner diameter are determined.
The radial load tolerance will be displayed, so please check it.

Enter the selection criteria

・Please use “.” for the decimal point and not “,” as the calculation error will occur.

Enter the shaft diameter

Shaft diameter: mm

Enter the transmissible torque

Transmissible Torque: N・m

Service factor:

Transmission capacity:kW

Rotational speed:r/min

If a thrust load is applied, input

Thrust load: N

If a radial load is applied, input

Radial load: N

Enter the yield point of the shaft and boss material

Shaft material yield point: MPa

Boss material yield point: MPa
