Description

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.
