Page 6: Displacements - Alignment Of The Couplings
In case of the alignment, the radial and angular displacement should be as slight as possible, because the lifetime is increased hereby under the same operating conditions. ® The alignment of the BoWex-ELASTIC HEW coupling has to be effected from the shaft-sided coupling hub to one of the processed surfaces of the flange hub. - Page 7 ∆Kw (°) max. perm. axial displacement 40 / 50 / 65 ±2 ±2 ±2 ±2 ±2 ±3 ∆Ka (mm) 1) for short-term start Schutzvermerk Gezeichnet: 08.04.04 Sha/Hk Ersatz für: KTR-N vom 01.12.99 ISO 16016 beachten.
