Micro cylinder with a width of only 12 mm

RCD micro cylinders are ultra-compact motorised rod type actuators with a width of just 12 mm and a housing length of 52 to 72 mm including servo motor and encoder.

The electric micro rod type is suitable for horizontal payloads up to 0.7 kg and vertical payloads up to 0.3 kg. It is available with 10, 20 and 30 mm stroke lengths. It achieves a speed of 300 mm/s at maximum acceleration of 1 G.

RCD micro cylinders are often used for positioning, press mounting or lifting and lowering workpieces instead of pneumatic cylinders.


Positioning & Precision

The RCD micro-cylinder allows positioning of up to 3, 256 or 512 points and adjustment of acceleration and deceleration as well as thrust force, which is difficult to realize with pneumatic cylinders.

By using a precision sliding screw (Ø 3 mm, pitch 2 mm), the repeatability is ± 0.05 mm with unidirectional stroke. RCD micro cylinders are therefore also suitable for demanding positioning tasks, e.g. in optical systems, in fiber optics technology or as micro actuators in medical technology.

Compressive force and speed

Despite its compactness, the RCD micro cylinder generates enough torque and a compressive force of 4.2 N through a brushless DC motor.

With the maximum acceleration/deceleration of 1 G and the maximum speed of 300 mm/s, the cylinder is used in many plants to reduce cycle time.

RCD-GRSN Mini 2-Finger Gripper

The 2-finger gripper has a total gripping force of 10 N with an overall height of only 22 mm. The maximum opening and closing speed is 67 mm/s with a repeat accuracy of +/-0.05 mm.

The small 2-finger microgripper is used wherever filigree products and materials are to be picked up and moved.

Application examples



Part push-out

Setting the appropriate acceleration/deceleration rate enables the Micro Cylinder RCD to push out a workpiece without impact.

Film tension adjustment

Capability for position adjustment based on a numeric value allows the Micro Cylinder RCD to achieve precise film tension adjustment.



Suction pads for height adjustment

Three-point positioning enables the Micro Cylinder RCD to handle a workpiece with variable height dimensions.

Workpiece alignment

Multiple Micro Cylinder RCDs can be used to position a workpiece precisely by pushing it from both sides.



Positioning workpieces of varying sizes on a conveyor belt

A single Micro Cylinder RCD can push and accurately position workpieces of different sizes.
