XC Advanced Anti-Backlash Supernuts

Thomson 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.
