Drives & Components Lubrication-free lead screw nuts

igus has expanded its range of lead screw nuts with the material iglidur E7 for trapezoidal and high helix lead screws. This is characterised by its smooth and low-vibration operation with low loads and high speed. With matching materials and geometries, the new lead screw nuts and the patented igus dryspin high helix thread technology provide optimum linear drive. In everyday life, they can be found everywhere, in the camera lens as well as in train doors—high helix and trapezoidal lead screws. They are used where precise adjustment is required. The lead screw units traditionally consist of two components—the lead screw and the associated nut. At high lead screw speeds, lead screw nuts made of standard plastics or metallic alternatives often reach their limits. The consequences are vibrations and noise. For this reason, igus has now added the material iglidur E7 to its range of lead screw nuts for high helix and trapezoidal lead screws. The nuts are specifically designed for high-speed applications with low loads and small installation space. Therefore, their use is ideal, for example, in fully automatic coffee machines, 3D printers or even in laboratory technology.
