Lubrication-freelead screw shop extend service life three-fold

page no 61

With the new durable material iglidur J200, igus expands its largest range of lead screw systems. In addition to the three common lead screw materials, depending on requirements, the designer can choose from nine different lubrication-free and maintenance-free nut materials. This now includes the high-performance iglidur J200 material with superior wear-resistant properties.

Adjustable lead screw drive systems for fast or slow positioning. They convert rotational motion into a linear movement. igus self-lubricating lead screw drives are used in a wide range of applications, including extendable platform steps on commuter trains, 3D printers and valve actuators and fittings in the chemical and process engineering sectors.

To address these diverse functions, the engineer can configure their design online in the iguslead screw configurator (, choosing from a wide variety of drive systems and technologies. In addition to metric threads, trapezoidal and high helix lead screw threads are available. The latter can replace toothed belt or pneumatic drives. With more than 70 different lead screw pitches, 3 lead screw materials and 9 different nut materials – such as the new durable iglidur J200 – in 10 different versions, igus offers the widest selection worldwide with more than 5,000 lead screw combinations.

iglidur J200: Up to three times longer service life
The new lead screw nuts are made of high-performance iglidur J200. In tests at the igus laboratory, this material achieved a service life three times longer than that of a standard material for nuts running on hard-anodised aluminium lead screws. When used in combination with aluminium, this new nut material reduces noise, dampens vibration and is lightweight. A typical application example
can be found in train and aircraft door systems, as well as applications in the handling and automation sectors. Cylindrical or flanged lead screw nuts are available to order from stock, which are also suitable for use on high helix and self-locking trapezoidal threads.
