Ball Screw Assemblies - Without Motors

Ball screws are precision mechanical assemblies consisting of helically threaded, hardened steel rods and a mating nut with recirculating balls, designed to convert rotational motion into linear motion with minimal friction and high efficiency. Miniature Ball Screw Assemblies, made in the USA by PBC Linear, combine precision-rolled 1050 steel screw shafts (diameters 6mm, 8mm, 10mm; lead sizes 1mm, 2mm, 2.5mm) with cylindrical, flanged, or externally threaded cylindrical nuts for easy installation and removal in automation and precision motion systems. Featuring a multi-liner ball return system, the nuts ensure smooth, efficient motion with consistent lead accuracy, outperforming lead screws in durability and precision under high loads. Two nut fit options (Standard & Transitional) enhance rigidity and positional accuracy, while polymer wipers at each nut end prevent debris ingress, extending service life in harsh environments like lab automation and medical devices. With a maximum static axial load capacity of 2.144 kN (482 lb), they support demanding applications, and shorter project lead times. Compatible with NEMA 08–23 motors, select assemblies integrate PowerPlus technology for 25–40% increased torque, making them ideal for robotics, CNC machinery, and industrial automation.

• More durable than lead screws with consistent lead accuracy
• Shorter delivery times from the factory west of Chicago
• Utilizes a multi-liner ball return system
• Static axial load: 2.144 kN (482 lb)
