Telescopic rails with optimal running properties thanks to inductively hardened raceways. Very minor bending even under maximum load in fully extended position. Six series (DS, DE, DBN, DMS, ASN, LTF) Torsionally rigid intermediate elements with S-shaped, double-T, or squared sections Over-extended, full or partial telescopic stroke extensions In DMS63 series the supported load can reach 2,000kg per pair. Extremely low deflection and smoothness of movement even in 24/7 high load applications Some series can be locked in closed position Special versions and strokes upon request. Packing could be customized according to your request.
