PTFE-free telescopic rail for continuous adjustment up to 2m

PETALING JAYA, Malaysia - May 9, 2025 - PRLog -- igus has introduced a new version of its drylin NT-60 telescopic rail, which uses iglidur JGPF sliding elements to ensure low-friction and quiet operation. This updated rail is free from PTFE and over 100 other PFAS compounds, addressing growing concerns over PFAS regulations. The system, available in sizes 35 and 60, can extend up to 2 meters and is used in vehicles, furniture, and medical technology.

The new drylin NT-60 telescopic rail looks identical to its predecessor, with three interlocking aluminium profiles measuring 60mm wide and 24mm high, and extendable up to 2 meters. It's available in full-extension and partial-extension versions, commonly used in camper drawers and home shelving systems. The key innovation lies in the sliding elements, now made from iglidur JGPF, a high-performance plastic free from PTFE, a type of PFAS. This change addresses potential future regulations or bans on PFAS substances.

Low-friction dry operation without PTFE
"The sliding elements made of iglidur JGPF impress in the NT-60-4 with a smooth and dry operation without additional lubricants. The telescopic rails can be pulled out much more reliably, with less maintenance and more hygienically than classic telescopic extensions with ball bearings. They are now also available without PTFE," says Hornung.  The new material has also been tested for around 100 other PFAS compounds, which the company believes are most likely to be affected by future restrictions. The new telescopic rail is available immediately. The rail profiles are available in silver or black anodised, and igus offers flat (NTKA-60) and high end caps (NTKB-60) as edge protection. Installation sizes NT-35 and NT-27 are also available in a PTFE-free version.

Still working reliably after 25,000 cycles
With the PTFE-free plain bearing material of the drylin NT-60-4 telescopic rail, the material development at igus once again shows that it is possible to dispense with PFAS without sacrificing technical specifications. The experts were able to prove the robustness of the material in the in-house test laboratory. Two telescopic rails from the drylin NT-60 series carried a centric load of 200N in a vertical installation position. The system was still functional even after 25,000 opening and closing cycles. "We attach great importance to successively expanding the drylin linear technology portfolio to include these robust, PTFE-free variants," says Hornung. "In addition to the telescopic rail series, the PTFE-free product range also includes drylin W solid plastic carriages, flat and pre-loaded prism carriages from the drylin N family and carriages from the drylin T series, which can also be retrofitted with PTFE-free sliding elements in existing systems."
