E Series push-rod motion device

Inner Structure

EQR Model

Product Principle

The E series is a modular product that integrates a servo motor with a ball screw, converting rotary motion into linear motion. It enables precise control of torque, speed, position, and thrust, providing high-precision linear motion and representing a new generation of automation drive solutions.

Product Advantages

1. High Stroke-to-Retracted-Length Ratio

The multi-stage telescopic structure overcomes the inherent limitations of conventional single-stage cylinders. When retracted, the individual stages nest inside one another, minimizing the overall installation length. When fully extended, multiple screw stages or synchronized belt drives operate in series to achieve a total stroke up to 23 times the retracted length. This configuration effectively solves a common engineering challenge: achieving a long lifting or pushing distance where the available installation space is limited. For example, it enables a mobile robot chassis to achieve a large height adjustment range without compromising ground clearance, or allows long-distance material transfer within a compact equipment enclosure.

2. High Rigidity with Multi-stage Guidance

Each telescopic stage is equipped with a long guide strip. Even at maximum extension, end-point deflection remains well controlled.

Rather than relying solely on conventional metal-to-metal sliding surfaces, each stage incorporates high-performance engineering plastic guide strips with a substantially larger contact width than conventional bearing arrangements. This creates surface support instead of point contact, maintaining concentricity and contact stiffness between the telescopic stages throughout the extension range while effectively distributing radial loads. Even at maximum working extension, end-point deflection under load can be controlled to the micrometer level, allowing end-mounted components such as grippers, platforms, and probes to maintain accurate trajectories during long-distance movement.

3. Integrated Anti-rotation Mechanism

Unlike many electric cylinders that rely on external linear guides or splined shafts to prevent rotation, this product incorporates a dedicated anti-rotation mechanism within the cylinder. The integrated design allows the cylinder to withstand axial thrust while providing controlled torsional rigidity, preventing the end flange or connector from rotating during lifting or pushing operations. For equipment integration, this eliminates the need for external linear guides, anti-rotation brackets, or auxiliary guide shafts, simplifying the mechanical assembly while reducing overall weight and cost. It is particularly well suited to compact automation systems where installation space and motion interference are critical considerations.

4. Designed for Vertical Lifting

Particularly suited to space-constrained vertical applications such as AGV lifting systems and stage equipment. In vertical applications, available installation height is often limited. With its compact retracted length and extended lifting height, the multi-stage electric cylinder is well suited to autonomous lifting and battery-swapping systems for AGVs and AMRs, as well as compact alternatives to scissor lift mechanisms and concealed lifting systems for stage lighting and audio equipment. Key benefits include reduced overhead or underfloor space requirements, secure braking, synchronized motion control, and reliable operation across varying environmental conditions.

 
 
EQR Model Ball Screw Type with Multi-Stage Telescopic

EQR Model Ball Screw Type with Multi-Stage Telescopic

The E Series is a modular product integrating a servo motor and ball screw, offering three load-based configurations. The EQR is a multi-stage telescopic electric cylinder using ball screws as the transmission component, providing higher transmission efficiency and precision. When driven by the motor, each stage of the screw and rod extends or retracts sequentially like an antenna, enabling synchronized telescopic motion with 3 or 4 extendable stages. It a direct-drive solution that packs precision, efficiency, and reliability into one package. Accuracy holds steady at ±0.01 mm; operation is smooth, quiet, and responsive down to milliseconds, while service life runs long. Add a force sensor, and you can pin force deviation to within 1%. Unlike conventional cylinders that rely on compressed air or hydraulic power, these units need only an electrical connection. They naturally support multi-axis synchronization and flexible motion sequencing. Mounting is adaptable, accessories can be mixed and matched, and interfacing with PLCs is straightforward. Today, you’ll find them hard at work in robotic arms, automotive welding lines, pick-and-place machines, and AGV logistics carts. Their proven performance has made them a go‑to choice for automation upgrades across the board.
