Rotary actuators with rack and pinion system Series QR
Magnetic, cushioned
7, 10, 20, 30, 50 mm
Rotation angles: 0 – 190°
7, 10, 20, 30, 50 mm
Rotation angles: 0 – 190°
The Series QR rotary actuators are cylinders with a double piston, able to provide high torques while ensuring high stability and a precise rotary movement.
The rotation angle can be easily set as desired between 0° and 190° by means of adjustment bolts or hydraulic absorbers positioned on one side of the rotary table. The use of shock absorbers allows the dampening of two to five times more kinetic energy than with regulation bolts. The rotary table is compact and allows direct mounting of the load. Their compact design, lightness and ease to combine with EOAT make these actuators particularly suitable for use in the assembly and packaging sectors and any application that requires transfer, tilting or rotation of objects.

General Data
| Type of construction | “Rack & Pinion” system |
| Operation | double-acting |
| Materials | profile, end blocks and rotor = aluminium – rack = steel – pinion = steel – rack’s guide ring = PTFE – seals = NBR |
| Type of mounting | by means of screws in the central body |
| Sizes | 07, 10, 20, 30, 50 mm |
| Operating temperature | 0°C ÷ 70°C |
| Standard rotation angles | 0 – 190° |
| Min. rotation angle (with shock absorber) | 10 = 66°, 20 = 52°, 30 = 46°, 50 = 70° (under these values the rotation is totally cushioned) |
| Repeatability [% FS] | <0,2° |
| Bearings | ball bearings |
| Operating pressure | 1 – 10bar, 1 – 7bar (for 7mm), 1-6bar (for versions with shock absorber) |
| Medium | filtered air in class 7.8.4 according to ISO 8573-1 standard. If lubricated air is used, it is recommended to use oil ISOVG32. Once applied the lubrication should never be interrupted. |
| Sensors | CSD |
Coding Example
