Interleaved gears are surface-hardened › Nearly maintenance-free › Increases effectiveness Everything’s included – series benefits Rotary pistons can be run to their end stop positions and loaded › No external end stops required Rotation angle or end stop query possible via camshaft › Precise positioning of rotation angle › Standard rotation angles 90°, 180°, 270° and 360° Greater working pressure › Up to 20% more power Shaft with bearing Bleed screws Load holding valve (optional, not shown) Sealing ring Regulating screw

Improved bearing efficiency with four-point bearing › For handling strong radial and axial forces › For greater longevity Any intermediate rotation angle possible › Customer-specific adaptation and integration into existing systems Improved end position cushioning › Soft braking of mass moments of inertia › Results in greater longevity for the entire system Angular adjustments › Precise travel to rear end position › ±4° angular adjustment State-of-the-art sealing technology › Ensures less wear › Longer service life for the entire system › No internal leakage › Increases safety Infinite...

When pressure is applied at P1, the drive shaft turns from its basic position towards the left (counter-clockwise). If pressure is then applied at P2 once the drive shaft has reached its final position, the drive shaft then turns back to its starting position (clockwise). The direction of rotation can be changed in a special-purpose model if required. P1 Starting position – pressure on P1 P2 Final position – pressure on P2

Take a moment to find the right moment Mt ≥ ML + MB Mt = Total moment ML = Loading moment MB = Accelerating/braking moment Details regarding calculation If a mass is subjected to a rotating movement with the angle φ in the time tges, from a standstill, external losses (frictional forces) need to be overcome, masses accelerated and subsequently delayed. The total sum of the resulting moments gives the required driving torque for the rotary actuator. When calculating, make sure that the following requirement is met in every possible rotating position: Depending on the position (horizontal,...

Tips for operating a rotary actuator Tips for continuous operation The values specified are effective values and may not be exceeded. When operating in multiple shifts with fast cycle times and very high continuous loads, we recommend taking a safety factor of 70% of the maximum permitted torque into account. It is sometimes necessary to change the hydraulic oil, depending on the size of the system. The smaller the system, the more often the oil needs to be changed. If the hydraulic fluid becomes contaminated in any way, it must be changed without delay. Purity class recommendation: ISO...

Screw connection Use the correct tightening torque to assemble the screw connections. Otherwise, the load capacity of the connection is reduced. In the worst case, the connection could even become loose. Tightening torque in Nm for cylinder screws in accordance with DIN EN ISO 4762 (12.9) Rotary actuator for display Pressure fluid Only mineral oils in accordance with Group HLP DIN 51524/ part 2 and VDMA sheet 24318 may be used. Their viscosity must be between 15 mm²/s (cSt.) and 250 mm²/s (cSt.). These conditions are equivalent to the hydraulic oils HLP 16 to HLP 46, depending on...
