Backup Safety Feature For Vertical Ball Screw Applications www.thomsonlinear.com A REGAL REXNORD BRAND

Maximizing Safety In Vertical Ball Screw Applications When installing a ball nut assembly in a vertical application, it can be critical to have a safety lock mechanism in the ball nut assembly to hold the load in the event of a ball nut failure. Thomson SFM safety nuts deliver reliable backup functionality for the traveling nut to ensure maximum safety. Flexible Design Options To best accommodate your application requirements, SFM safety nuts are available in various sizes. The safety nut is an optional part to a ball screw assembly and mounted below the traveling nut without any axial load applied....

The normal function of the unit is guaranteed up to an axial play of 0.4 mm. Note: The safety nut can only be installed together with the corresponding flanged nut. Thomson also offers complete units with integrated safety nuts (flanged and cylindrical).
