Actuators
Whether it's a simple Rotary-Lift Combinations, Rotary Actuator or, Part-turn Actuator we can supply your needs.
Rotary Actuators
Applications:
The applications for our rotary actuators cover the whole of the industrial sector such as construction machinery, machine tools, bending machines, foundry, mining, agricultural and packing machines, transfer lines, manipulators, armatures, shipbuilding, vehicle and ventilation techniques etc.
HKS rotary actuators are remarkable for the following reasons:
 | 20 sizes up to 250,000 Nm with pistons 40-450 mm diameter |
| 4 rotary angles: 90°, 180°, 270° and 360° for each size |
| actuator shaft with 2 feather keys or DIN 5480 involute spline |
| tandem seals on the drive shaft |
Auxiliary Equipment
| cushioning at both ends |
| rotary angle adjustment to ± 4° |
| camshaft |
| hollow shaft with DIN 5463, DIN 5480 or DIN 6885 profile |
Special Versions
| actuator shaft with spline profile to DIN 5463 |
| actuator shaft with second drive cogs |
| actuator shaft and mounting flange to customer's requirements |
| angle adjustment over the whole rotation area |
| limit switch equipment |
| direct valve connection |
| 3 mounting positions |
| all intermediate rotation angles can be supplied |
| rotation area over and above 360° |
| sea-water resistance |
| additional bearing for higher radial forces |
| change of rotation direction |
| further special types available |
| working pressures up to 250 bar and more can be supplied upon request |
Rotary-Lift Combinations
In the course of technological development, more and more work cycles have to be automated. For rotary and lifting movements, which have to be executed simultaneously or separately, the rotary-lift combinations from HKS offer you the ideal solution.
Here we have combined the well-established HKS rotary actuator with a doubly effective linear unit into a compact component.
The optimum unit can be chosen from two types for each special use.
Applications
HKS rotary-lift combinations can be used in the whole of the industrial sector such as machine tools, glass-manufacturing industry, bending machines, transfer lines, handling techniques, shipbuilding, vehicle and ventilation techniques etc.
