Pushing the two nuts toward each other eliminates backlash between the two nuts and leadscrew. The nut offers adjustable drag torque — it can be very low for light loads or high for heavy loads. The nut is a proprietary blend of self-lubricating polyacetal and precisionrolled 303 stainless-steel screw material. Its self-lubricating properties make these nuts suitable for applications in the medical and food-processing industries, or wherever precise positioning is required.
