Product description
Lead screw nut product description
dryspin lead screw nuts are made of iglidur high-performance polymers. There are 6 different standard materials available for different applications: iglidur J, iglidur J350, iglidur A180, iglidur E7, iglidur R, iglidur J200 and iglidur W300 (only TR). The use of different tribologically optimised materials enables lead screw technology to meet many of the required specifications. B. High load resistance, temperature resistance or FDA conformity.
The dryspin® lead screw nuts are made of highly wear-resistant iglidur® high-performance polymers and are therefore 100% lubrication-free and maintenance-free. They are durable and tough in adverse environments. They also score points with their resistance to chemicals, freedom from mould and quiet travel. All standard materials are PTFE-free. The base material is also reinforced by technical fibres or filling materials. The solid lubricants are, as 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.
Temperature resistance also plays a major role in many applications. It is often suggested that polymer lead screw nuts can only be used at low temperatures. But that is not true!
It should always be noted that the axial clearance in the lead screw system is directly influenced over a wide temperature range. The specifications of the axial clearance are based on laboratory tests and an ambient temperature of 23°C.
