    Shown with Rotary Shaft (Not

    Included)

    Install these nuts on a rotary shaft to create a linear positioning system without a lead screw. Instead of threads, a set of angled ball bearings drives the nut along a shaft as it spins. Nuts move towards you when the shaft rotates clockwise and away from you when the shaft rotates counterclockwise. To prevent overload damage, these nuts can be adjusted to slip and stop travelling at a given thrust load. Thrust loads are loads that are applied parallel to the shaft. Bearings are permanently lubricated to save maintenance time and effort.
