Electric Actuators – AC Servo Sliders

Ball Screw Drive

Ball Screw Drive

The AC servo version of the LEFS slider features an AC servo motor instead of a DC version. The AC servo motor enables higher speed and acceleration, as well as improved vertical load capability in the size 40 model. The drivers are pulse input type, with both incremental and absolute encoder options and 17- or 18-bit resolution.


Belt Drive

Belt Drive

The AC servo version of the LEFB slider features an AC servo motor instead of a DC version. The AC servo motor enables higher speed and acceleration, as well as a size 40 model not available in a DC version. The drivers are pulse input type, with both incremental and absolute encoder options and 17- or 18-bit resolution.


High Rigidity Ball Screw

High Rigidity Ball Screw

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. The drivers are pulse input type, with both incremental and absolute encoder options and 17- or 18-bit resolution.

The LEJB is a slider type electric actuator available exclusively with an AC servo motor. The actuator features a substantially wider load mounting platform than the LEFB, supported internally by a double axis linear guide for reduced moment deflection. The AC servo motor enables higher speed and acceleration, improved positioning repeatability, and a high-load size 63 model exclusive to LEJ. The drivers are pulse input type, with both incremental and absolute encoder options and 17- or 18-bit resolution.


Support Guide

Support Guide

An LEFG guide shares dimensions with the LEFS and LEFB body, but has no motor. It functions as a support for a significantly overhanging workpiece that is moved by a driving slider. The guide is equipped with a seal band that prevents the ingress of grease and other external foreign matter. A typical application is in support of a large loading platform in a multi-axis pick-and-place operation
