The new RCP2 series of IAI's product line RoboCylinder®

The Electromechanical Alternative to Pneumatic Cylinders
At the newly developed electrical cylinder series RCP2 IAl improves the rigidity and optains a high usibility: Electrically driven cylinders can be steered better than pneumatical and can run into very exactly inter-positions. They are economical in the acquisition and show a thrifty energy balance.

The new RCP2 series of IAI's product line RoboCylinder® consists of a ballscrew, a linear guide and an encoder controlled stepper motor. Besides its efficiency, rigidity and functionality it is suitable for many applications thanks to its universal construction. The improved use qualities of the electrical cylinder are based on several performance features: quiet run, simple maintenance and multi-point positioning.

The RoboCylinder® increases the economicalness of various small batch productions and solves various tasks in production lines. The new type with its 52-80 mm wide aluminum bottom body - depending on model - was included into the slider program. This explanation has the triple payload of previous manufactured widest execution of the first RCP generation with 58 millimeters. The explanation of the new rod type is 25-64 mm wide (depending on mode) and just more reduces the size of the mechical equipment.

About IAI's product line RoboCylinder®:

The RoboCylinder® is a flexible, intelligent, and economical, ballscrew linear actuator from Intelligent Actuator. Economical and easy to use, the RoboCylinder® is specifically designed to accomplish the simple tasks usually assigned to air cylinders, but with greater flexibility and control. Offering custom control over position, speed, acceleration, deceleration, and torque, allowing for mid-move velocity changes, and control from a PLC, the RoboCylinder® is a versatile and easy-to-use alternative to pneumatic cylinders. RoboCylinders are available in a wide variety of configurations to suit the requirements of your specific application. The main variations are found in the basic body construction and the type of motor employed. The new and improved RCP2 series & ERC series utilize a hybrid stepper motor ideal for low-speed, high-thrust applications. For constant thrust across a wider range of speed, actuators of RCS series, which employ AC servo motors, are ideal. Both the RCP and RCS series of linear positioning actuators are available in an extensive array of rod, slider, and flat type configurations, accommodating a wide variety of application requirements.

The RCP and RCS actuators have different characteristics. The RCP actuators have higher payload capabilities at lower velocities. As the payload increases the RCP actuator will start decreasing in velocity according to it's pulse motor torque curve. The RCS actuators will maintain a constant velocity throughout it's payload rating. Once the payload rating has been exceeded the AC servo motor will cause the controller to fault out.

Depending on ballscrew lead, all RoboCylinder® actuators are available in high-, medium- and low-speed models. The Slider type is capable of speeds up to 1000mm per second, and the Rod type up to 800mm per second. RoboCylinders are typically used in single axis applications for simple point to point positioning. They may also be integrated into multiple axis Cartesian positioning systems from IAI's product line IntelligentActuator®.
