General information

Features and applications

Together with NSL screws, NSF nuts form a system for converting rotation into linear motion (see Fig. 1).

The self-lubricating technopolymer structure ensures maximum cleanliness as it does not require lubrication with oils and greases.

They are often used in the packaging sector.

Thanks to the high wear resistance of the material, NSF-W nuts are particularly suitable for use in the presence of processing residues and dust such as those coming from woodworking machines and laboratory instruments.

Thanks to its material that has been approved for contact with food (FDA EU 10/2011), NSF-F nuts are particularly suitable for use in the food and pharmaceutical industries.

To complete the system, position indicators and handwheels can also be integrated (see Fig. 1).
