Lead screw nut made of iglidur® J350 - high-temperature material for temperatures of up to +150°COur lead screw nut made of the high-performance polymer iglidur® J350 allows use at permanently medium to high ambient temperatures. The long-term application temperature should ideally be between +60°C and +150°C in order to obtain the maximum performance.
Further advantages are:
► Dimensionally stable even at high temperatures
► Can be certified according to EN 45545 HL3, R24
► Good coefficient of friction at medium loads
► Application range of up to +150°C long-term application temperature
► Permissible permanent surface pressure in the thread pitches 0MPa to 3.0MPa

All our lead screw nuts are made from 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- 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:
