Exploring the SFU1204’s Applications:
- Linear Actuators:
The simplest way to use the SFU1204 is to mount it using a Ball Screw Support at each end and a Ball Nut Housing to hold and move a Gantry Plate. Make sure to use a Floating Support like the FF10 Floating Ball Screw Support on the floating end of the Ball Screw and a Fixed Support such as the FK10 Fixed Ball Screw Support for the fixed end.
Then you can use a DSG12H Ball Nut Housing mounted on your Ball Nut and attach it to whatever you need to move, or use a Gantry Plate for a larger surface area.Other Mounting:
If the FF and FK Supports aren’t the right fit for you, try the Base Mounted Options: the BF10 Floating Ball Screw Support and the BK10 Fixed Ball Screw Support. We also have the 12mm Ball Screw Kit – SFU1204 – 1500mm – Type A which includes the base-mounted options instead.
- 3D Printing:
Enhance precision in your 3D printing projects. Pair the SFU1204 with our 3D Printer Controller Pack including Mega 2560 and RAMPS 1.4 for optimal control. Also compatible with our Nema 17 Stepper Motors for smooth and accurate movement. - Robotics:
Build or upgrade robotic arms and manipulators with the SFU1204. Check out our Robotics parts to find some commonly used components, or look at our curated MakerBotics selection. Our 12V-24V Geared-DC Motors can also be used for additional power and control in your robotic projects. - CNC Machine Upgrades:
If you’re someone who’s confident enough to build some custom plates for your CNC routers, mills, and lathes, the SFU1204 will improve the accuracy and motor efficiency of your machine. For further upgrades, consider using this ball screw with our popular xPRO V5 Motion Control System or E5X MCS T4.1 for enhanced machining accuracy. - DIY and Hobbyist Projects:
The SFU1204 is perfect for hobbyists creating custom machinery. Grab an Arduino and a Sensor Pack and you can create enough stuff to keep you busy for years.
