In addition to the standard stroke lengths specified in the above table for linear actuators any stroke inside the maximum stroke length is available. By means of linear actuator connectors, the linear movement of the lead nut can be transmitted externally via a follower. The followers are inclu- ded with the respective linear actuator connectors. In addition, the tube clamp connector range contains many different parts for mounting the linear actuators. In order to measure the displacement and positioning of the linear actua- tor connectors, the square tube can be provided with a longitudinal scale. see also... • Linear Actuators GN 291 → Page 1950 • Longitudinal Scales GN 299 → Page 1982 • Linear Actuator Connectors → Page 1954 ff. • Handwheels for Linear Actuators → Page 1984 ff. • Installation Kits GN 296 (for Position Indicators) GN 296 → Page 1987 Information • Square tube - - Steel, chrome-plated SCR - - Stainless steel AISI 304 NI * • Spindle with trapezoidal thread - - Steel respectively Stainless steel AISI 303 - - Ball bearing • Lead nut Gunmetal • End plug Plastic • Stainless Steel Characteristics → Page 2166 • RoHS Specification 4 • Linear actuator connectors, tube clamp connectors and accessory have to be ordered separately.
