Description

Ball Screw Mechanism CAD (Free) – Compact Linear Drive Design

This free ball screw CAD design gives you a compact linear motion mechanism ideal for small machines, actuators, and mechanical R&D projects. The assembly includes a rotating ball screw shaft driving a carrier via precision bearings — all modeled in detail.

It’s perfect for CNC prototype builders, robotics enthusiasts, and mechanical engineers looking to learn or expand on motion transmission principles.
