dryspin® lead screw nut, metric thread, RSRM

Lead screw nut made of iglidur® R - for medium to high speeds - dampening
Our lead screw nut made of the high-performance polymer iglidur® R enables a reduction of the vibrations between the lead screw and the lead screw nuts through its dampening properties and ensures a low-vibration and low-noise running behaviour.
Other advantages include:

► High wear resistance at low loads
► Soft material - vibration-dampening
► Application range up to +90°C upper long-term application temperature
► Permissible permanent surface pressure in the threads 0 - 2.0MPa

All our lead screw nuts are made of the wear-resistant iglidur® high-performance polymers.
There are seven different standard materials available for different purposes: iglidur J - high efficiency at all speeds, iglidur J350 - for temperatures up to +150°C, iglidur A180 - FDA-compliant for the food and pharmaceutical industry, iglidur E7 - for high speeds with low loads, iglidur R - anti-oscillation and anti-vibration, iglidur J200 - the best counter partner for aluminium and iglidur W300 - for heavy-duty applications. 

This gives you the following advantages according to the materials:
► 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 compliance through A180
► Withstanding 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 chambers of the material. This is adequate to sufficiently lubricate the immediate surrounding area and to reduce the friction of the system. These additives significantly stabilise our lead screw nuts for wear resistance.

In addition to a large selection of standard materials for lead screw technology, igus also offers a wide range of variants in the lead screw nut geometry itself:
Cylindrical lead screw nuts
Cylindrical lead screw nuts with spanner flats
Flange lead screw nuts
