SFU1605 Ball Screw Set RM1605 From NUIBBYED
The SFU1605 RM1605 kit from NUIBBYED provides a 16 mm diameter ball screw with a 5 mm lead, designed for CNC machines and precision stages. Included components feature the BK12 and BF12 end supports, a coupling, a ball screw nut, and a mounting set. The assembly uses bearing steel and aluminum alloy elements to balance rigidity and weight. This package is suitable for users who need a ready-to-install solution with standard end supports for X–Y table setups or compact CNC projects.
CHUANGNENG SFU1605 RM1605 1500mm Kit
This CHUANGNENG kit expands to 1500 mm and includes SFU1605-1500MM components, BK12/BF12 end supports, a 6.35 mm x 10 mm shaft coupler, and a DSG16H ball nut housing. It emphasizes long service life through low friction and reduced noise, making it suitable for CNC routers and automated measurement stages. Its design targets electronic machinery and factory automation, offering strong reversibility and stable positioning performance across longer travel lengths.
Zeberoxyz SFU1605 Ballscrew Nut 16mm 5mm
This Zeberoxyz SFU1605 nut is designed for high accuracy and efficiency, with an inner diameter of 16 mm and a 5 mm lead. The assembly uses bearing steel for durability and maintains low friction for smoother motion and reduced heating. The design is compact for easy installation and removal, supporting precise linear motion in CNC carvers and CNC milling scales that require robust performance over extended travel.
250mm SFU1605 Ball Screw Set RM1605
The 250 mm variant from NUIBBYED extends the same 16 mm diameter and 5 mm lead, offering a compact yet longer travel option for builders needing a longer axis. The package includes one ball screw, one nut, BK12/BF12 end supports, and a coupler, enabling straightforward integration into DIY CNC machines, gantries, or lab measurement setups where moderate travel is required without sacrificing precision.
uxcell SFU1204 Ball Screw Nut (12×4)
uxcell’s SFU1204 nut features a 12 mm inner diameter and a 4 mm lead, suited for smaller-scale CNC components and hobbyist projects. The nut is machined from high-strength bearing steel and is designed for low friction, high stiffness, and long service life. It is ideal for compact X–Z axes, table-indexing stages, or mini milling assemblies where space is at a premium but precision must be preserved.
Buying Guide: Key Purchase Considerations
- Travel length and compatibility: Ensure the travel length matches your axis requirement. Longer kits like 1500 mm are suitable for large gantries, while 250 mm or shorter kits suit compact machines.
- Lead and precision: A 5 mm lead offers good balance between speed and resolution for most hobbyist to prosumer projects; 4 mm is common in smaller assemblies, offering higher precision at slower speeds.
- End supports and mounting: Confirm included BK12/BF12 supports or plan for compatible end housings. Proper mounting reduces runout and improves rigidity.
- Material and durability: Ball screws use bearing steel for durability; look for low-friction designs to minimize heat build-up and wear in continuous operations.
- System integration: Check for included nuts, couplers, and brackets. Some packages include end-machined components, reducing setup time.
- Length vs stability: Longer screws can sag under load; consider using supports or a gantry with cross-bracing to maintain straightness over travel.
- Noise and maintenance: Low-noise options help in workspaces; consider lubrication requirements and accessibility for periodic maintenance.
- Compatibility with motion control: Ensure your controller, driver, and limit switches align with your screw pitch and axis configuration for accurate positioning.
Across these options, users should weigh travel length against budget and mechanical complexity. For hobbyists, compact 1204 or 1605 configurations with standard end supports provide a solid starting point. For more ambitious CNC builds, longer RM1605 kits with complete mounting hardware enable smoother, high-precision movement. Always verify the included components and refer to manufacturer guidance for installation torque and lubrication intervals to optimize performance and longevity.
