Specifications for mounting linear motors
Mounting system
The following specifications apply when mounting primary sections and secondary sections to
the machine:
• Use M5 screws with property class 10.9. (friction value μ

• Only use new screws that have not been used before.
• Ensure that the correct types of mounting screws are used to fasten the secondary sections:
– Cylinder head screws with standard head for 1FN3050 to 1FN3150 according to
• Ensure that the mounting surfaces are free of oil and grease and are clean and unpainted.
• Comply with the optimal surface roughness depth Rz of the screwing surface. Rz is between
10 and 40 μm.
• Minimize the number of joints. This keeps the settling effect for the material and the screws
low.
• Carefully maintain the specifications for the thread depths and screw-in depths in the primary
section.
• The tightening torque is 7.6 Nm.
Tighten the fixing screws using torque control. If you cannot tighten the fixing screws using
torque control, at least use a calibrated torque wrench with a short wrench insert.
You can increase the load capability of the screwed connection when using a tightening
procedure with controlled angle of rotation or yield limits.
• Tighten the screws gradually, with no jerky movements.
• To secure the screws, select a long clamping length l
Alternatively, use a medium strength threadlocker to prevent screws becoming loose, e.g.
Loctite 243.
• Minimize the amount that the screws settle. To do this, retighten all screws.
