High Rigidity Ball Screw, Wide Body

The LEJS High Rigidity Ball Screw Wide Body series is a specialized slider that features a substantially wider load mounting platform supported internally by a double-axis linear guide. This wide-body construction is engineered to reduce moment deflection and handle larger loads, with the size 100 model capable of supporting up to 400 kg. For applications requiring both high speed and long distance, a specific variation is available that includes an internal intermediate ball screw support (or supports) to prevent vibration and whipping of the screw during high-speed rotations.

25A-LEJS, AC Servo Motor

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.

LEJS, AC Servo Motor, Electric Actuator

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.

LEJS, Motorless, Ball Screw Drive

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

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, Motorless, Ball Screw Drive

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.
