Maintenance-free actuators

Feb. 13, 2013
The new Type ES and Type EC actuators offer long–term maintenance-free operation.

The new Type ES and Type EC actuators offer long–term maintenance-free operation. Featuring a caged-ball LM guide-type SRS and rolled ball screw equipped with a QZ Lubricator, the Type ES actuator operates for extended periods without requiring maintenance. Caged technology uses a synthetic resin cage with a patented curvature that cradles each ball and separates it from the next one. The spaces between the rolling elements retain grease to act as a lubrication system. The guide also acts as its base. The ES comes in four models with widths ranging from 32 to 50…mm, heights from 40 to 52.5…mm, and strokes from 50 to 600…mm.

The Type EC actuator also uses a rolled ball screw equipped with a QZ Lubricator and comes in two models with widths ranging from 40 to 48…mm, heights from 48.5 to 57.5…mm, and strokes from 50 to 300…mm.
