The load data apply to GN 291, GN 292, GN 293 linear actuators made of steel (SCR) or stainless steel (NI). |
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 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 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 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 |
