The Eckart rotary-linear actuator HSE4 is a combination of a rotary actuator and a double-acting linear cylinder. The maximum operating pressure of the HSE4 is100 bar. Low friction seals allow the rotary-linear actuator HSE4 to operate from as low as 10 bar operating pressure and so can be eco- nomically set at approximately 20 bar.For especially slow rotation stick-slip seals can be supplied as aspecial specification rotation movement: The piston K of the rotary actuator (fig.-2) moves linear by a hydraulic force between the two mechanical end stops E1 and E2. This linear movement will be...

From view F, the piston rod KS will rotate anti-clockwise (arrowA) when pressure is applied to port A1. A different direction of rotation is available as a special feature. The hydraulic fluid used in the rotary-linear actuator does not exceed the pollution classification 19/15 in accordance with ISO 4406. Therefore, a filter setting of < 25 > m should beinstalled in the pressure line. With hermetically sealed containers a return filter should suffice. At open containers a pressure filter must be installed in the pressure line. The maintenance intervals described above should be adhered to...

Apart from our standard version with flange-mounting, you havealso the option of version with foot-mounting. The angle of rotation can be adjusted individually with this option, both over its total range of rotation and over a partial range (e.g. total angle 270 , desired partial adjustment of 180 to 270 ). To this end, the adjusting insert RE is simply screwed inwards or outwards to give the desired angle of rota- tion. The shaft goes all the way through, allowing control equip- ment to be fitted. Adjustment is only possible in the unpressurised state. The total length of the rotary...

Because of its torque, angle of rotation, pressure range, po-sitioning accuracy, stability of position, type of attachment and dimensions, the Eckart HSE4 rotary actuator can be used in a wide range of applications.The selection and the size depends above all on the de-mands and the operating conditions under which the rotary- linear actuator is operating. For the planning of specialitems, it is also important for us to be aware of all technicaldetails.We accept no guarantee claims for disturbances in functio-ning or complaints which are attributable to lack of infor- mation by the...
