Ultra-compact RCD Micro Cylinder with Servo Drive

World's smallest rod type including servo motor and encoder

RCD Micro Cylinder at Smart Prices

The new low-priced RCD micro cylinder with a cross section of only 12 mm with a body length as short as 60 mm expands the IAI product range for applications with small load and power requirements. It is small enough to replace compact air cylinders used for short-stroke travel, pressing, hoisting, etc.

The ultra-compact linear cylinder with 24 VDC micro motor is available with stroke lengths of 10, 20 and 30 mm. The small 2.5 W motor provides a rated thrust of 4.2 N, a maximum load of 0.7 kg and a speed of up to 300 mm/s at an acceleration of up to 9.81 m/s².

Precision lead screw

The use of a precision lead screw (Ø 3 mm, lead 2 mm) facilitates linear movements with a repeatability of ± 0.05 mm with uni-directional useful travel. The combination of brushless 2.5 W permanent magnet motor, high-resolution encoder (440 pulses/revolution) and an ultra-compact frame guarantees maximum precision and is ideally suited for demanding positioning tasks e.g. for optical systems, glass fibre technology, or as micro-adjustment drive in the medical technology field.

High-speed performance

The small 2.5 W motor provides a rated thrust of 4.2 N, a maximum load of 0.7 kg and a speed of up to 300 mm/s at an acceleration of up to 9.81 m/s². Its high-speed performance with maximum accelleration/deceleration of 1 G is highly effective in reducing cycle time in a variety of systems.

3-point positioning and easy acceleration rate adjustments

The Micro Cylinder RCD easily achieves 3-point positioning and acceleration/deceleration rate adjustments, which are difficult to achieve using air cylinders. Push-motion operation similar to that available with air cylinders is also possible, and the force exerted during a push-motion operation is adjustable.

Application Examples

Film tension adjustment

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


Part push-out

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

Suction pads for height adjustment

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

Workpiece positioning

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.
