The specified forces Fy and Fz cause a flexure of the guide tube of approx. 0.5 mm. A lead nut moves in axial direction over the ball bearing trapezoidal thread spindle of the linear actuator. The follower ensures the anti-rotation and makes the link to the different linear actuator connectors. The linear actuators have been designed for manual operation (handwheel). The positioning accuracy is 0.2 mm / 300 mm stroke, the maximum reverse play is 0.1 mm. Guide tubes are available in chromed steel (SCR) or stainless steel (NI) non-rusting. They are made with the tolerance range of precision steel tubes DIN 2391 or DIN 2462. A wide variety of different components are available in the tube clamp connector program to fix the linear actuators in place and to upgrade these into linear actuator connectors. Also, digital position indicators (GN 953 / GN 954 / GN 9053 / GN 9054 → Page 396 / 398 / 402 / 404 ) may be attached to measure the displacement or the positioning. In applications where high torsion forces Mx occur, linear actuators with square tubing or double tube linear actuators should be given preference. A wide variety of different components from the tube clamp connector program is also available for the square tubings. The linear actuator connectors are composed of two-part elements, with the effect that the precision of the square tubes involves no special requirements.
