KTR-N 40110 EN ® BoWex Sheet: 9 of 22 Operating/Assembly instructions Edition: Assembly 4.2 Advice for finish bore The maximum permissible bore diameters d (see chapter STOP 1 - technical data) must not be exceeded. If these figures are disregarded, the coupling may tear. Rotating particles may cause danger to life.
KTR-N 40110 EN ® BoWex Sheet: 10 of 22 Operating/Assembly instructions Edition: Assembly 4.3 Assembly of the hubs We recommend to inspect bores, shaft, keyway and feather key for dimensional accuracy before assembly. Heating the hubs lightly (approx. 80 °C) allows for an easier mounting on the shaft. Please pay attention to the ignition risk in potentially explosive atmospheres! Touching the heated hubs causes burns.
KTR-N 40110 EN ® BoWex Sheet: 11 of 22 Operating/Assembly instructions Edition: Assembly 4.4 Displacements - alignment of the couplings The displacement figures specified in tables 6 and 7 provide for sufficient safety to compensate for external influences like, for example, thermal expansion or foundation settling. In order to ensure a long service life of the coupling and avoid dangers with the use in potentially explosive atmospheres, the shaft ends must be accurately aligned.
