The tubes of telescope linear units VT1S are made of chrome-plated steel or bright, seamless stainless steel precision tubes. A continuous spindle with ball bearings on each side is installed in the guide tube. The attached spindle nut transmits the linear movements to the telescope tube, initiating an adjustment of the telescope linear unit travel distance.
The guide tube is fitted with sliding inserts and forms a solid linear round guide together with the telescope tube. The linear unit can be adjusted for low backlash or clamped in place via the slitted guide sleeve. The drive is situated on the end, allowing the telescope linear unit to be fastened from the side. Depending on the type of fastening, the drive of the linear unit remains at the fastening point or is carried along by the travel movement.
Accessory parts are listed in the tables and are already taken into account when selecting the linear units. This ensures that the length of the shaft journal z is correct for attaching the accessories, for example. The accessories are not included with the linear units and must be ordered separately.
