Lead screw nut made of iglidur® A180 - FDA-compliant for food and pharmaceutical industryOur lead screw nut made of the high-performance polymer iglidur® A180 is FDA-compliant and suitable for applications with low to medium loads in the direct environment or contact with food or drugs as well as moisture. Other advantages include:
► FDA-compliant - for food contact
► Compliant with Regulation (EU) No. 10/2011
► Application range up to +90°C upper long-term application temperature
► Permissible permanent surface pressure in the thread pitches 0 - 3.5MPa
All our lead screw nuts are made of the wear-resistant iglidur® high-performance polymers. 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 compliance
► Stability of high loads
► Long-term application in temperature ranges from -20°C to +150°C
The base material is additionally reinforced by 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 stabilise our lead screw nuts decisively for wear resistance.
There are 7 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 and pharmaceutical industry, iglidur E7 - for high speeds with low loads, iglidur R - vibration damping, iglidur J200 - best mating partner for aluminium and iglidur W300 - for heavy-duty applications.
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:
