AC Servo Sliders
Similar to the Slider type except utilizes an AC servo motor instead of a DC type. The AC servo motor enables higher speed and acceleration, as well as improved vertical load capability. Optional drivers include pulse input and various communication protocols including Ethernet. Encoders range from 17 to 22-bit resolution, depending on motor selection.
AC Servo Ball Screw Drive
The AC Servo Ball Screw Drive is a slider-type electric actuator that utilizes a ball screw drive to provide high-precision linear motion. By incorporating an AC servo motor, this series achieves superior speed, acceleration, and vertical load capacity compared to standard DC models. The load mounting platform is positioned above the drive mechanism and is protected by a flexible seal band that prevents foreign matter from entering the internal components. This actuator is available in body sizes 25, 32, and 40, offering a maximum workload of 60 kg and a maximum speed of 1500 mm/s with positioning repeatability of plus or minus 0.02 mm.
High Rigidity Ball Screw Drive
The LEKFS High Rigidity Ball Screw Drive series represent a significant mechanical upgrade over standard sliders by employing a redesigned guide system. These actuators use four rows of circular arc groove guide rails instead of the standard two, which increases the allowable moment rigidity and reduces table displacement under heavy loads. These models maintain high precision with a positioning repeatability of ± 0.01 mm.
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.
AC Servo Type Belt Drive Products
The AC Servo Belt Drive is designed for applications that require longer strokes and higher speeds than what a ball screw can typically provide. This series features a load mounting platform driven by a high-strength belt, allowing for strokes up to 3000 mm and speeds reaching 2000 mm/s. Like its ball screw counterpart, it utilizes a flexible seal band to maintain internal cleanliness and offers flexible motor mounting options on either the top or bottom of the unit. The LEFB is frequently selected for rapid transport over long distances where high-resolution positioning is required across an extended range of motion.
LEJB, Electric Actuator, High Rigidity Belt Slider, Wide Body, AC Servo Motor
The LEJB High Rigidity Belt Drive Wide Body series combines the stability of the wide-body double-axis guide with the rapid travel capabilities of a belt drive. Exclusively available with AC servo motors, this series is intended for high-speed transport where stability and reduced moment deflection are critical. It offers body sizes 40 and 63, reaching speeds of 3000 mm/s while maintaining a positioning repeatability of plus or minus 0.04 mm. This makes it an ideal solution for large-scale automation where workpieces must be moved quickly without sacrificing the structural integrity of the motion system.
Large Load Belt Sliders
The LET-X11 Large Load Belt Sliders are heavy-duty actuators engineered to handle massive horizontal workloads up to 240 kg. These sliders feature a transverse mounted motor with four different orientation options to allow for optimal machine layouts in tight spaces. A key design feature is that the mounting table is the highest surface of the actuator, ensuring that large workpieces can travel without interference. This series is built for durability and ease of maintenance, with an accessible drive belt and reduction ratios that can be customized to prioritize either maximum speed or maximum load capacity.
LEFG, Support Guide, Ball Screw/Belt Drive
The LEFG is a non motorized support guide that shares the same body dimensions and mounting patterns as the LEFS and LEFB electric actuators. It's designed to support overhanging workpieces or to act as a secondary rail in multi axis systems, ensuring that the load is distributed evenly without requiring a second powered motor. It features the same protective seal band as the driven sliders to prevent contamination and maintain a clean operating environment.
