¹⁾ Misalignment at n = 1500 rpm.

Angular and radial misalignment can occur at the same time. The sum of all misalignments must not exceed the figures set forth in the table. Couplings may be dynamically balanced on request.

Assembly Guidelines

During assembly, the coupling halves must be mounted in a way that the coupling hub faces are flush to the end of the shafts. The alignment of the shafts must be adjusted that radial and the angular misalignments are minimal. The life of the coupling and bearings is extended by precise alignment. Steps must be taken to ensure that the alignment will not change during all operating conditions. Shaft misalignments which cannot be avoided must not exceed the figures indicated in the table. Angular and radial misalignments can occur at the same time but the sum of these misalignments must not exceed the figures set forth in the table above. See the KTR mounting instructions, KTR standard 49510 at our homepage www.ktr.com.
