Lead screw nut made of iglidur® J350 - high-temperature material for temperatures up to +150°COur lead screw nut made of the high-performance polymer iglidur® J350 allows use in permanently medium to high ambient temperatures. The long-term application temperature should ideally be in the temperature range from +60°C to +150°C in order to be able to obtain the maximum performance from the material.
Other benefits:
► Dimensionally stable even at high temperatures
► Certifiable according to EN 45545 HL3, R24
► Ideally suited for the railway industry
► Good coefficient of friction for medium loads
► Up to +150°C max. long-term application temperature
► Permitted continuous surface pressure in the threads from 0MPa to 3.0MPa

All 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 up to +150°C, iglidur A180 - FDA-compliant for the food-pharmaceutical industry, iglidur E7 - for high speeds at low loads, iglidur R - vibration-dampening and vibration-inhibiting, iglidur J200 - best mating partner to aluminium and iglidur W300 - for high-load applications.
Depending on the material, this gives you 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 through A180
► Withstands high loads
► Long-term use in temperature ranges 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 of tiny compartments of the material. This is adequate to sufficiently lubricate the immediate surrounding area and to reduce the friction of the system. These additives stabilise our lead screw nuts decisively for wear resistance.
In addition to 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:
