1. Technical data
Technical data, such as dimensions, weights, performance data, peak torques, operating life and
operating temperature ranges, etc., relating to the ARPEX couplings listed in these operating instructions
are documented in the product catalogues set out in table 1 and can be made available on request or
accessed on the Internet at any time (see back cover).
Where the coupling design deviates from that shown in the respective catalogue, an order­specific
dimensioned drawing containing all the required technical data is enclosed with the delivery.

These data together with the contractual agreements on the coupling determine the limits of its proper use.
Limited temperature ranges apply to use in potentially explosive environments in
accordance with Directive 2014/34/EU. The classification in temperature classes is
shown in item 5.3, "Conditions of use".
For sustained faultfree operation the coupling must be designed with an application
factor appropriate to the application. In the event of a change in operating conditions
(output, speed, changes to the prime mover and driven machine) the design must
always be checked.
