Information

In addition to the standard stroke lengths of the linear actuators GN 291 specified in the table, any stroke within the maximum stroke lenghts is available upon request.

A wide variety of different components are available in the connector clamp range to mount the linear actuators in place and to upgrade them to linear actuator connectors.

In order to measure the movement or the position of the linear actuator connectors, digital as well as analog position indicators can be attached. Also, the guide tube can be equipped with a longitudinal scale.

The load data apply to GN 291, GN 292, GN 293 linear actuators made of steel (SCR) or stainless steel (NI).
The specified forces Fy and Fz cause a flexure of the guide tube of approx. 0.5 mm.

Description

A lead nut moves in axial direction over the ball bearing trapezoidal thread spindle of the linear actuators. The drive key ensures the anti-rotation and provides the connection to the different linear actuator connectors. The linear actuators are designed for manual operation (handwheel).

The positioning accuracy is 0.2 mm / 300 mm stroke, the backlash is max. 0.1 mm.

Guide tubes are available in chrome plated steel (SCR) or stainless steel (NI). They are manufactured with the tolerance range of DIN 2391 or DIN 2462 precision
steel tubes.

A wide variety of different components are available in the connector clamp range to mount the linear actuators in place and to upgrade them to linear actuator
connectors.

Also, digital position indicators (Digital Position Indicators EN 953 / Digital Position Indicators EN 954 / Digital Position Indicators EN 9053 / Digital Position Indicators EN 9054 may be attached to measure the movement or the
position.

For applications where high torsionional moments Mx occur, linear actuators with square tube or double tube linear actuators should be given preference.

Also for square tubes there is a wide variety of different components available from the connector clamp range. The linear actuator connectors are composed of
two-part elements, with the effect that the precision of the square tubes involves no special requirements.
