Material:
Material: Sliding hub: steel, zinc-plated and
chromated yellow, asbestos-free and rustproof friction pads.

Elastic coupling: coupling hubs cast iron,
insert (toothed ring) Polyurethane. Hardness 92° Shore (optional 98° Shore).

The slipping torque can be adjusted with common assembly tools for screws.
The elastic coupling can be mounted in axial direction.
Torque can be altered after mounting.
By mounting a second disc spring, the torque range can be doubled
(second spring has to be ordered separately).
Customized bores and feather-key grooves available at extra charge.

1) above Ø 19 mm with flat keyway DIN 6885/3.
* Essential for dimensioning.
** Nominal torque of the elastic coupling.
*** Maximum torque of the elastic coupling.

Material: Special spring-steel.
Delivery per piece.
At all sizes of FA and RNR, the specified torque can be doubled by the addition of a (second) disc spring.
At sizes from 01 to 5, the specified torque can be tripled by the addition of a (third) disc spring.
The minimum torque setting is then approx. 65% of the maximum value.
