ETN rollers were developed with respect to centre guided rope and hydraulic elevators. The roller trestle is made of a high-strength light metal alloy. All rollers have a coating made of Vulkollan® which has a small rolling resistance. It is noise and oscillation absorbing with the least settling phenomenon of all highly loadable elastomers and has an excellent resistance to wear. It is also resistant to fat and oil. Vulkollan® is a registered trademark of Covestro Group. Visit Website: ETN
