Ball Screw and Lead Screw Assemblies

Ball Screw & Lead Screw Assemblies

Ball screws use helical grooves to guide ball bearings in a nut, providing movement driven by motors (NEMA 08–23) or hand cranks. PBC Linear provides precision-rolled 1050 steel screws (diameters 6, 8 and 10 mm, leads 1, 2 and 2.5 mm) with cylindrical or flanged nuts in assemblies.

Lead screws offer more cost-effective motion through sliding contact between threads and a nut. PBC Linear provides PTFE-coated stainless steel screws for corrosion resistance, low wear, and minimal flaking, while offering a wider range of screw diameters and lead sizes. The lead screws are delivered in assemblies with round or triangular nuts, some with patented Constant-Force Anti-Backlash technology to reduce backlash. 

Compatible with NEMA 08–23 motors, select ball screw and lead screw assemblies integrate PowerPlus motor technology for 25–40% increased torque, ideal for precision-driven applications like lab automation and medical devices.
