It is very important that couplings are correctly aligned installed within practical limits, so that maximum performance and an extended service life is achieved.

With all Euroflex couplings, the installation and alignment procedures for the specific coupling are given.  However the general principles of alignment are detailed below:

1. Mount the respective coupling hubs on the drive and driven machinery shafts, such that the hub face is flush with the shaft ends.
2. Maintain the distance between the two shaft ends as indicated in the coupling assembly drawing .  Unless otherwise stated in the specific coupling installation instruction, the following limits should be used when measuring the distance between flange faces.

4 bolt couplings: +/- 0.50 mm

6 bolt couplings: +/- 0.40 mm

8 bolt couplings and over: +/- 0.25 mm

1. An initial and rough alignment should be made by laying an straight edge across the flanges of the two hubs.
2. For final alignment, attach two dial indicators as shown in the figure.  align the equipment to within the max. TIR of 0.05 mm.
3. Tighten all fasteners to required torque limits as specified on the drawing.
4. Final check is to be done with several rotations to ensure that the TIR is within 0.05 mm.
