Note 1) The female thread material is premised to withstand the bolt tightening torque
2) Recommended bolt: Hexagonal bolt per JIS B 1176 Intensity category: JIS B 1051 12.9 or higher
3) Calculation conditions Torque efficiency: 0.2 Tightening efficiency: 1.4 Tightening friction coefficient:
0.15
Precautions on installation
When designing the assembly, take note that application of any abnormal or excessive force that
causes deformation of the installation surface may result in performance drop. To demonstrate the
excellent performance of the SHA series actuator fully, take note of the following points:
Warping or deformation on the machine mounting surfaces
Foreign matter on the mounting surfaces
Raised burrs or deformation around the tapped mounting holes
Insufficient chamfering of mounting pilot diameter
Mounting pilot diameter is out-of-round
When the installation method is as shown in assembly example 2
mentioned above, the recessing shown to the right is recommended
for the spigot corner section on the actuator fixing member.
