The specified forces Fy and Fz cause a flexure of the guide tube of approx. 0.5 mm.

Description

The slider is moved via a bearing-type trapezoidal thread spindle and a guide nut. The slider is guided through two parallel chrome-plated tubes, resulting in a high load capacity and allowing high bending moments to be compensated by the linear actuator.

For type GN 492, a second slider and an adapter plate extend the options for applications.

These double tube linear actuators have been designed for manual operation (handwheel). With the appropriate lubrication, they can also absorb rotary spindle speed of as much as 250 rpm.

The positioning accuarcy is 0.2 mm / 300 mm travel, the maximum revers play is 0.1 mm.

To measure the adjustment or the positioning, digital position indicators DD52RDD51DD52R-EDD51-E may be attached. The required extension of the shaft journal is enabled by installation kits GN 491.1.
