Product description
The guide tubes of the linear actuators GN 2931 are made of square tubes of chrome plated steel or stainless steel. Two independent spindles with ball bearings at both ends are installed within the guide tube. The thread direction of the spindles can be chosen independently for each side. The guide nuts on each of the spindles transmit the linear movements to the linear actuator connector along the guide groove via a follower, independently of the opposite side.
A solid linear square guide is created by connecting the guide tube with the holes of the linear actuator connectors. The square shape is particularly suited for receiving torsional forces. Multiple connector types are available and can be adjusted or clamped with low backlash thanks to the split design of the holes. Depending on the setup, either the part to be moved is fastened to the connector or the connector itself is installed at the application site such that the entire linear actuator moves.
The overview offers a range of possible accessories that can be installed on the linear actuator in the various configurations. The design and length of the journal varies depending on the accessories, and this must be considered when selecting the linear actuator. The accessories are not included with the linear actuators and must be ordered separately. For assistance, please consult the overview of types on page XYZ.
Linear actuator connectors are also needed to build a functioning linear actuator. A wide range of different versions are available to meet the needs of the specific application. The overview of types on page XYZ can assist in making a selection.
