SFU1204 Ball Screw with Nut 12mm Diameter 300mm Length High Precision Linear Motion Ballscrew with Machine Ending

SFU1204 Ball Screw with Nut 12mm Diameter 300mm Length High Precision Linear Motion Ballscrew with Machine Ending

SFU1204 Ball Screw with Nut 12mm Diameter 300mm Length High Precision Linear Motion Ballscrew with Machine Ending

• The SFU1204 ball screw 300mm is designed for smooth, efficient linear motion in compact CNC and automation systems.
• Featuring a 12mm diameter screw and 4mm lead, it delivers precise travel and repeatable positioning.
• Supplied with a single ball nut and C7 precision, this CNC ball screw is a solid choice for applications that need reliable motion control, low friction, and consistent accuracy.
• The SFU1204 ballscrew is a compact, high-precision linear motion component designed to convert rotary motion into smooth, efficient linear travel.
• This set includes a 12mm diameter screw, a matched ball nut, and machine-ended shaft journals for easier installation with standard supports/couplers.
• Ideal for low-backlash, repeatable positioning where stable thrust and smooth movement are required.

Applications SFU1204 Ballscrew

• CNC routers and small CNC milling/engraving machines
• 3D printers and precision linear stages
• Automated fixtures, pick-and-place systems, and gantry axes
• Linear actuators, robotics, and motion control projects
• Upgrades from lead screws where higher efficiency and lower backlash are needed

Features SFU1204 Ballscrew

• High efficiency linear transmission compared to trapezoidal/lead screws
• Smooth motion with reduced friction and stable thrust capacity
• Supports precise positioning and repeatability for CNC and automation
• Lower backlash potential (especially with suitable preload / higher accuracy grades
• Compact 12mm profile fits small machines while maintaining rigidity
• Machine-ended shaft simplifies assembly with couplers and bearing supports
• SFU1204 ball screw 300mm Suitable for high-duty cycle motion systems when properly lubricated and aligned

Package Includes

• 1 piece of SFU1204 ball screw 300mm
