The shaft distance (A) denotes the exact distance between the input and output shaft
The maximum outer diameter (a) not only refers to the hub diameter (b), but also includes the bellows or interference contours.
Radial clamping hubVery simple fitting, by tightening only one radially arranged clamping screw (DIN 912). One hole in the housing is sufficient, for tightening the screw
Split-HubAdmissible seat clearance shaft-hub: min. 0,01mm /max. 0,04mm. Two lateral clamping screws (DIN 912) are arranged oppositely. The hubs or couplings are split and consist of two loose halves. One of the split-hubs can be put onto the aligned shaft. Tighten clamping screws evenly, alternating between both sides (note specified tightening torques). A larger opening must be provided in the housing for easy installation.
Lateral clamping hubAdmissible seat clearance shaft hub: min. 0,01mm / max. 0,04mm. Very simple fitting by tightening only one laterally arranged clamping screw (DIN 912). The value for the relevant tightening torques can be found in the data sheets. One hole in the housing is sufficient to tighten the clamping screw (see EASY-clamp sytem).
Konus-Klemmnabe/SpannringnabeAllowable clearance shaft hub: max.0,02mm. For the ESM-A coupling type, an axial plug-in installa-tion is generally required. For this purpose, both hub parts are previously fastened on the drive and output shaft, the star is inserted into a claw hub, and finally the other claw hub is pushed onto the star by means of an axial mounting force. The conical clamping ring is fastened from “inside” by tighten-ing the fastening screws with hexagon socket crosswise. The hub clearance dimension “g” must be observed and checked. Several release threads are provided for releasing the cone hub.Keyway connectionA keyway can also be provided on customer request for a form-fitted shaft-hub connection.

Operating temperatures
As an all-metal coupling, metal bellows couplings are extremely insensitive to temperature. Series with aluminum clamping hubs can be used without restrictions from -40 ° C to 150 ° C, briefly up to + 200 ° C. In the case of series with welded steel or stainless steel hubs, the maximum operating temperature is 350 ° C. The application limit of the elastomer couplings is 90 ° C (98 Sh-A) or 120 ° C (72 Sh-D).
The axial pluggability is achieved by a backlash-free keyway connection in whole metal version (aluminum anodized). For this, one part of the hub is delivered as a conical carrier, the counterpart with a congruent conical keyway.

Very seldomly, metal bellows couplings may have resonance sounds (e.g. a whistling or a humming), when coupling types with a higher torsional stiffness or vibration reducing elastomer couplings are recommended.
