Tandler Precision (UK) has released its new R+W SK range of torque limiters. This range is used to protect highly dynamic drives. A new dedicated design has now been introduced for applications in clean rooms in food, electronic and pharmaceutical production. To protect the coupling from the ingress of dirt, aggressive cleaning detergents and other manufacturing fluids, the SK range can be specified completely sealed. This option also ensures no grease can leak out of the coupling. An o-ring is inserted in the base element of the coupling and covered by an extended actuation ring. This arrangement ensures the external dimensions of the coupling remain unchanged. Four designs complete this 0.1 to 2800Nm range. The SK1 is for timing belt and chain applications, SK2 has a clamped hub for direct drives and SK3 a tapered clamp connection for direct drives. SK5 is a press fit version. The sealing option is available on all types. Nitrocarburised, oxidised and nickel plating may be specified for all steel types in the range. The complete product programme is also available in stainless steel.
