Motorized Lead Screw Assemblies with Triangle Nuts
Lead Screw Assemblies with Triangle Nuts offer a combination of precision lead screws, durable nuts, and high-quality NEMA motors to ensure exceptional performance. This assembly features a triangle nut lead screw known for its triangular shape, which enhances stability and load distribution. Assemblies are available in a variety of 3 to 11 standard combinations of lead screws and nuts, along with five frame size options: NEMA 08, 11, 14, 17, and 23. These assemblies offer options for standard or anti-backlash nuts, as well as left and right end machining. The factory-fixed screw and motor guarantee optimal alignment, reducing costs and allowing for a more compact design. Users benefit from 30% more torque, while the larger bearings—designed to support the lead screw—offer increased thrust capacity and longevity. Hollow shaft concentricity minimizes screw runout, and the preload on bearings eliminates axial play for enhanced stability and accuracy.
