Thompson BSA's XC series of lead screw nuts has the best anti-backlash technology, using a stainless steel cam (ActiveCAM®) to create a solid bias between the nut halves. A torsional spring maintains the tension between the parts, while still having low torque and drag. The ActiveCAM® design results in the stiffest assembly possible using polymer lead screw nuts. Every movement with XC series lead screw nuts is exact and repeatable. This provides a light- and medium-duty anti-backlash screw that rivals ball screws for precision.
