Featured Product from Rockford Ball Screw
The safety spring is a coiled spring in the inactive part of the ball nut that conforms to the ball screw thread. The spring is inactive during normal operation and does not contact the screw. In the rare event that the balls are lost from the ball nut, the safety spring will support the load and prevent the nut from “free falling” down the screw. Safety springs are mandatory if the ball nut is used to lift, and/or support people to prevent the ball nut from a free fall condition in case of a ball nut catastrophic failure.
The spring is not designed to maintain normal operation and the ball screw assembly should be taken out of service after first engagement of spring. Safety springs are available for all ball screw models. Please inform our customer representative that you require the safety spring for your application.
