An electrical actuator is primarily used where intermittent axial movement and positioning is needed. It is a good alternative to hydraulic and pneumatic cylinders due to the simple connection to electrical operational systems and to the hygienic benefits. Furthermore, you will achieve a steady speed all over the load range compared to hydraulics and pneumatics solutions. The dynamic tensile/compression force is up to 29,4 kN of standard products. Higher force can be achieved by customised solutions. Actuators with trapezoidal spindle This type of actuator is simple and of a sturdy construction. It is based on our worm gearboxes on which a set of cylindrical stainless steel tubes and an inner threaded spindle are mounted. Using a ball screw it is possible to achieve linear movements of up to approx. 6,500 mm/min. on standard products. Higher speed can be achieved by customised solutions.

Protection:
The protection of the stainless steel actuator is IP69K which ensures that the product can be cleaned with water under pressure from all directions. To be more accurate the actuator is to be sprayed with water from angles of 0°, 30°, 60° and 90° with an interval of 30 seconds in every position and at a distance of 10-15 cm. The water must be at least 80° C and the water pressure must be 14-16 litres per minute. Furthermore, the product is placed on a turntable that rotates 5 rpm. This degree of protection can only be achieved with an equivalent high degree of protection against dust which results in the designation of IP69K. This approval is especially used in the food industry
