Lead screw nut made of iglidur® W300 - for heavy-duty applications of up to 5MPa Our lead screw nut made of the high-performance polymer iglidur® W300 allows for a high wear resistance at high loads and/or abrasive ambient media. Of all iglidur® materials, iglidur® W300 is the most resistant to these conditions. It should be noted, however, that for lower loads or highly dynamic applications, iglidur® J (all-rounder) is probably a better choice as the material tends to vibrate at low loads due to its high strength. We will be happy to help you with the right material selection. Other advantages include:
► Wear-resistant at high loads - high static strength
► For low speeds
► Application at long-term temperatures of up to +90°C
► Recommended continuous surface pressure in the thread pitches 4.0MPa to 5.0MPa

All of our lead screw nuts are made from the wear-resistant iglidur® high-performance polymers.There are seven different standard materials available for various applications: iglidur J - high efficiency at all speeds, iglidur J350 - for temperatures of up to +150°C, iglidur A180 - FDA-compliant for food and pharmaceuticals, iglidur E7 - for high speeds at low loads, iglidur R - vibration-dampening, iglidur J200 - best mating partner for aluminium and iglidur W300 - for heavy-duty applications.
Depending on the material, you have the following advantages:
► 100% lubrication-free and maintenance-free
► Durable and robust in adverse environments
► Chemical-resistant and mould-free
► Quiet and vibration-free travel
► PTFE-free
► FDA conformity due to A180
► Support of high loads
► Long-term use in temperatures from -20°C to +150°C
The base material is additionally reinforced with technical fibres or fillers The solid lubricants are microscopic particles, embedded in millions in tiny chambers of the material. This is adequate to sufficiently lubricate the immediate surrounding area and reduce the friction of the system. These additives stabilise our lead screw nuts decisively for wear resistance.
Apart from a large selection of standard materials for lead screw technology, igus also offers a wide range of options for the lead screw nut geometry itself:
