igus intoduces leadscrew nuts made of iglidur E7 tribopolymer

Safe, fast and quiet adjustment, these are the essential requirements for leadscrew modules. With this in mind, igus has expanded its range of leadscrew nuts with the material iglidur E7 for trapezoidal and high helix leadscrews. This is characterised by its smooth and low-vibration operation with low loads and high speed.

Robert Dumayne, dry-tech director at igus says: "In everyday life, linear drives can be found everywhere, from camera slides to train doors, wherever precise adjustment is required. Leadscrew units traditionally consist of two components: the leadscrew and the associated nut. At high adjustment speeds, leadscrew nuts made of standard plastics or metallic alternatives often reach their design limits. The consequences of which are unwelcome vibration and noise."

For this reason, igus has added the material iglidur E7 to its range of leadscrew nuts for high helix and trapezoidal lead screws. The nuts are designed specifically for high-speed applications with low loads and small installation space. Typical application examples include fully automatic coffee machines, 3D printers or even in laboratory technology.

In comparison to other leadscrew nuts materials, iglidur E7 is a high-performance polymer that is self-lubricating and therefore maintenance free. The softer material reduces noise while at the same time acts as a vibration-dampening device.

The in-house wear comparison test between iglidur E7 and the igus standard material revealed the new material offers superior performance. The iglidur E7 leadscrew nut at 135rpm and a load of 100N has four times higher wear resistance on a high helix leadscrew and 19 times better wear resistance on a trapezoidal leadscrew. With matching materials and geometries, the new leadscrew nuts and the patented igus dryspin high helix thread technology provide the optimum linear drive.

With the help of the handy online tool, called the leadscrew module expert, designers can assemble the appropriate linear drive, including nut, with just a few clicks for immediate order and dispatch. For more information about drylin linear drives, please visit www.igus.co.uk/drylin.
