Fully assembled and tightened to the required torque with screw locking compound, for example, adhesive used If there is no marking, you must assume that the condition is pre-assembled. Check all bolted connections and tighten them to the specified torque. If in doubt, contact REICH. - Page 42 Mounting the coupling In the pre-assembled condition, the components are bolted together but not to the required torque. The pre-assembled condition can be recognised by the red tag or adhesive label attached in the factory. All bolts are to be tightened to the specified torque.

or on a heating plate. The recommended temperature can be calculated depending on the tolerance pairing. Contact REICH in this respect. Place the heated coupling hub onto the shaft of the driven machine. Make sure that the coupling hub cools uniformly. Quenching is prohibited. -
Page 47: Aligning The Coupling
Mounting the coupling Make sure that the markings from joint balancing are in alignment. Mount the flexible coupling element on the coupling hub. Tighten the bolts to the required torque. Aligning the coupling CAUTION! Increased rate of wear to the flexible coupling element due to inadequate alignment of the drive unit and the driven machine. - Page 48 Mounting the coupling Precise alignment has a positive effect on the service life of the coupling and other system components. We therefore recommend using only up to 20% of the permissible radial and angular displacements for the alignment of the installation. During alignment, it is essential to take into account the usual setting behaviour of the unit bearings as well as temperature-related changes in length that influence the mounting length.
- Page 49 Mounting the coupling The permissible coupling misalignment limits are dependent on multiple factors such as coupling size, element hardness, operating speed and torque stress. The guideline values listed in the following table apply to a medium element hardness and a typical speed up to 1500 min Coupling size Maximum permissible misalignment...
