1、 H i-Precision K now-howS ervice 5 1324Dirt, dust, moisture.? So what!Whoever thinks that such high precision is sensi-tive, is in for a pleasant surprise: exactly the op-posite is true for the HKS rotary actuators. Withworking pressures of up to 350 bar, they requirea strong, well-sealed housing. T

2、his also providesexcellent protection to the interior. Our rotaryactuators are therefore completely immune todust, dirt, and moisture. It is therefore no won-der that one can rely completely on them evenunder the most difficult conditions, whether deepunderground in mines or 2,300 meters under seale

HKS rotary actuators again proved theirreliability in the raising operations on the Rus-sian atomic submarine Kursk.Our rotary actuators have also acquired an ex-cellent reputation where the highest levels ofcleanliness and hygiene are necessary. For ex-ample, their reliability is highly valued

4、 in the phar-maceutical industry and in food production be-cause of their cleanliness in operation.Precision at the limits of the possibleThe linear movement of the hydraulic piston isconverted into rotary movement by means ofmultiple helical gears. This is the same principlea drill uses.The helical

5、 gears thus convert hydraulic pressureinto very high torque levels. For rotary-liftcombinations a linear movement is added to therotary one.The principle is quite simple, however a great dealof precision is necessary to give our rotaryactuators their function and well-knownreliability. This precisio

More important forpractical use, however, is the fact that all themodular units in our rotary actuators ca
