Ball Screw with Nut SFU2005 (20mm Dia - 5mm Pitch -up to 2000mm Length)

Overview

Upgrade your CNC machine or automation project with the SFU2005 ball screw assembly from MOKWN. Engineered for precision and efficiency, this ball screw converts rotary motion into smooth, near-frictionless linear motion. With a 20mm diameter and a 5mm lead, it offers an excellent balance of speed and resolution, making it a popular choice for 3D printers, laser engravers, and custom CNC routers. Available in lengths up to 2000mm, this ball screw provides the accuracy and reliability your projects demand.

Key Features

• High Efficiency: Ball bearings reduce friction to less than 10%, maximizing power transfer.
• Precision Positioning: Consistent 5mm pitch ensures accurate, repeatable linear movement.

MOKWN Recommendation

For a complete motion system, pair this ball screw with our BK/BF bearing supports and a flexible shaft coupling. If you need custom end machining (threading, turning, or drilling), contact our support team before ordering. For high-speed applications, consider the SFU2005 with a higher lead (10mm or 20mm) for faster travel.
