High Rigidity Ball Screw, Wide Body
The LEJS is a slider type electric actuator available exclusively with an AC servo motor. The actuator features a substantially wider load mounting platform than the LEFS, supported internally by a double axis linear guide for reduced moment deflection. The AC servo motor enables higher speed and acceleration, as well as a high-load size 63 model exclusive to LEJ. Optional drivers include pulse input and various communication protocols including Ethernet. Encoders range from 17 to 22-bit resolution, depending on motor selection.

The LEJS is a high-rigidity slider characterized by a low-profile design and a low center of gravity, which enhances stability during high-speed motion. Driven by an AC servo motor and a ball screw, it can handle workloads up to 85 kg while maintaining a positioning repeatability of ±0.02mm. Its construction is optimized to reduce the overall height of the system by 36% compared to similar models, making it a powerful yet compact choice for high-performance automation.

This version of the LEJS electric actuator offers the same high-rigidity, low-profile mechanical benefits as the standard model but is delivered without a motor. It features universal mounting patterns compatible with motors from manufacturers such as Sanyo Denki and Panasonic, allowing for custom motor and driver pairings. It’s useful for facilities that have standardized on a motor brand but require the mechanical stability and high-load capacity of the LEJS slider.
LEJS63-M, High Rigidity Ball Screw Slider, Wide Body, High Speed with Intermediate Supports
The LEJS63-M is a specialized wide-body electric actuator that introduces internal intermediate ball screw supports to allow for long strokes without sacrificing speed. These supports travel with the slider to hold the ball screw in place, eliminating the vibration that usually occurs at high speeds over long distances. This innovation allows the actuator to maintain maximum velocity throughout its entire stroke, making it ideal for large-scale automation projects that require rapid, long-distance linear movement.
LEJS63N-M, Electric Actuator, High Rigidity Slider, Ball Screw Drive, High Speed with Intermediate Supports, Motorless
Similar to the LEJS63-M, this model is engineered for high-speed operation over long strokes by utilizing intermediate ball screw supports to prevent vibration. Its core benefit is the ability to achieve high-velocity linear motion without the typical mechanical limitations of long-length ball screws. It provides a stable, high-precision solution for wide area manufacturing applications.
25A-LEJS, High Rigidity Ball Screw Slider, Wide Body, AC Servo Motor, Secondary Battery
The 25A-LEJS combines the high rigidity, wide body design of the LEJS series with material compatibility for secondary battery manufacturing. Like other 25A-series products, it eliminates copper and zinc and uses low-dew-point grease to ensure safe and reliable operation in battery production environments. This model is well suited for battery assembly lines that require the movement of heavy loads with high precision and stability in specialized atmospheric conditions.
