⚙️Product Description:
Sourcing high-efficiency linear drive components for miniature precision machinery? Our RMO Brand SFU1204 Precision Rolled Ball Screw features a compact 12mm shaft diameter, a 4mm lead/pitch, and a tailored total length of 215.5mm. Engineered with an integrated flanged single nut, this ball screw converts rotary motion into high-precision linear displacement with maximum mechanical efficiency and minimum backlash. As a trusted B2B trading expert, we supply cost-effective RMO factory-direct wholesale quantities or seamlessly source premium global motion control brands to safeguard your project budget.
⚙️Product Features:
- High Positioning Accuracy & Low Backlash: Advanced cold-rolling manufacturing ensures a continuous, high-precision raceway groove, delivering smooth micro-feeding and eliminating positioning errors.
- Optimized Mini Dimensions: Precision-engineered with a 12mm outer diameter, 4mm lead, and 215.5mm total length, perfectly tailored for compact linear actuators and miniature CNC axis assemblies.
- Exceptional Mechanical Efficiency: Employs smooth-circulating steel balls to achieve over 90% transmission efficiency, requiring significantly lower driving torque compared to conventional standard lead screws.
- Hardened Carbon Steel Structure: Fabricated from high-grade carbon steel with induction-hardened raceways, ensuring outstanding wear resistance, stiffness, and structural longevity under cyclic stress.
- Flexible B2B Sourcing Alternatives: Maximize your trade distribution profit with direct bulk orders of our high-margin RMO brand linear line, or source certified premium legacy global brands through our secure network.
⚙️Product Application:
Specially designed to provide smooth linear motion and rigid precision in compact structures, the SFU1204 ball screw is widely utilized in:
- Desktop 3D printers (Z-axis drive), micro CNC routers, and DIY engraving machinery.
- Medical diagnostic instruments, laboratory automation pipetting stages, and laser scanning hardware.
- Semiconductor assembly systems, micro-robotics linkages, and electronic pick-and-place fixtures.
- Automated optical inspection (AOI) setups, small packaging machines, and precision XY linear stages.
- Global linear motion hardware distributors, B2B automation component wholesalers, and machinery OEM buyers.
⚙️Precautions:
| 1. Keep clean | 2. Use with caution | 3. appropriate tool | 4. Hot-loading | 5. Be careful of rust |
| Dust will have a bad effect on the bearing, so keep the surrounding clean. | Strong impact during use can easily cause scratches and indentations. | Avoid replacing existing tools, and use appropriate tools. | Bearings are precision parts, so hot installation is recommended. | Sweat on your hands during operation will cause rust, so it is best to wear gloves. |
