3.4 Alignment and Coupling
The drive’s free shaft end must be connected to the surrounding system by a force-fit, free of play, zero-
backlash coupling.
First choices are, for example, metal bellow, collet chucks, or shaft-hub joint coupling. They form a frictional
connection and are capable to transmit the occurring torque. As with all rigid couplings, an adequately accu-
rate radial, axial, and angular alignment of the two connecting shaft ends is essential.

Check original manufacturer’s specifications
Consult the specifications of the coupling manufacturer prior installation.
Comply with original manufacturer’s specifications and respect permissible loads
• Make sure to not exceed the permissible axial force of 270 N during assembly or disassembly.
• Make sure to align the coupling according to the manufacturer’s specifications.
• Make sure that the axial and radial forces that are going to occur during operation will not exceed the lim-
its stated (
“Mechanical data” on page 2-14).
