Engineering Your Linear Motion Solutions
Ball screws are precision mechanical components that convert rotational motion into linear motion using a threaded shaft and a nut with recirculating balls to minimize friction. The Ball Screw Assemblies from PBC Linear combine precision-rolled 1050 steel screw shafts (diameters 6mm, 8mm, 10mm; lead sizes 1mm, 2mm, 2.5mm) with cylindrical or flanged 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. Optional preload enhances 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.
