THE igus PTA polymer telescope extension, available from Treotham Trading , has a three part design to eliminate joining elements and hardware.
The full extension has freely selectable lengths and can be equipped with locking functions at both end positions, while the PTA’s low headroom saves valuable space, and floating bearings easily level up.
The PTA system can be delivered pre-loaded. In this case small spring elements pre-load the components of the subassembly free from clearance. The PTA has a cushioning stop motion device with elastic elements this eliminates the clearance of single components and avoids noises such as rattling.
The PTA does not require lubrication or maintenance, and is corrosion-free. Despite its low weight it offers high robustness and stiffness.
The product is suitable for automotive construction, the furniture industry, interior fitouts, medical experiments and machine construction.
A range of 21 materials is available to suit different applications. Materials containing plastic compounds offer resistance to high temperatures, sliding speed, chemicals and dirt.
