Rubber coupling on end.

To satisfy starting and running characteristics of industrial machines Fluidomat offer three circuit types to give starting torque down to 120% of nominal torque.
Type SM and HF are basic coupling without delayfil chamber. Starting torque adjustable in the range of 180% to 275%.
Type SMD and HFD are couplings with delayfil chamber. Starting torque adjustable in the range of 140% to 275%.
Type SM-DX and HF-DX are couplings with extended delayfil chamber. Starting torque adjustable in the range of 120% to 270%.
Normal operating slip – 2% to 5% depending on coupling size and starting torque value.
Fusible plug blow off temperature 130°C as standard. Optional 160°C.
Suitable for two consecutive starts from hot and three from cold.

Coupling types SM/SMD/SM-DX are supplied in finished bores on the fluid coupling shaft. However where it is not possible to specify finished bores at the time of ordering, we can provide a seperate shaft bush. The allowable maximum bore in the shaft bush is denoted by Ød5 shown in the dimension table.
