  • Cylindrical lead screw nut with flange
Product description
Lead screw nut made of iglidur® W300 - for heavy duty applications up to 5MPa
 
Our lead screw nut made of the high-performance polymer iglidur® W300 enables iglidur® W300 the lead screw nut 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 only be noted that for lower loads or very dynamic applications, iglidur® J (all-rounder) is probably a better alternative (we will be happy to help you with the right material selection), as the material tends to vibrate at low loads due to its high strength. Other advantages include:
Wear-resistant at high loads - high static strength
for low speeds
Application range up to +90°C upper long-term application temperature
Recommended permanent surface pressure in the thread pitches 4.0-5.0MPa

All our lead screw nuts are made of the wear-resistant iglidur® high-performance polymers.
There are 7 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 - depending on material - 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 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 strengthen 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 variants in the lead screw nut geometry itself:
Cylindrical lead screw nuts
Cylindrical lead screw nuts with spanner flats
Flange lead screw nuts
Flange lead screw nuts with spanner flats
Heavy-duty lead screw nut geometry
Cylindrical injection-moulded lead screw nuts
Injection-moulded lead screw nuts with flange
