The SFU4010 super-heavy-duty ball screw establishes new benchmarks in industrial transmission, specifically engineered to withstand the most extreme loading conditions. Featuring an innovative multi-row ball arrangement with staggered configuration, it significantly enhances system rigidity and load-bearing capacity through optimized force distribution paths. The unique double-layer thermal insulation combined with active cooling technology effectively manages temperature rise during high-load operations, ensuring consistent precision output during prolonged continuous operation. With its reinforced sealing system and intelligent lubrication device working in synergy, this ball screw delivers reliable transmission solutions for demanding applications including mining machinery, heavy-duty presses, and large-scale port equipment operating in challenging environments.
| Feature Aspect | Description |
|---|---|
| High Rigidity & Backlash-Free | Gothic arch groove design enables four-point contact between balls and raceways. Axial backlash can be eliminated through preload adjustment, preventing slippage even in vertical installations, ensuring positioning accuracy and rigidity. |
| High Efficiency & Low Torque | Rolling friction replaces sliding friction, with driving torque only one‑third or less of that of a sliding screw. Efficiently converts rotary motion into linear motion with minimal energy loss. |
| Micro-Feed Capability | Supports micro‑feed increments down to micron level or even within 0.1 μm, meeting high‑precision application requirements such as precision machining and positioning. |
| Internal Circulation Structure | Adopts an internal circulation design, resulting in a compact nut structure that saves installation space, suitable for equipment with limited internal space. |
| Excellent Durability | Manufactured with rigorous material selection and heat treatment processes, combined with strict quality control procedures, delivering high reliability and long service life. |
| High Load Capacity | Dynamic rated load reaches 5399 kgf, static rated load 15500 kgf, and rigidity 73 kgf/μm, capable of handling heavy‑load operating conditions. |
| Wide Range of Applications | Suitable for CNC machine tools, industrial machinery, automation equipment, robotics, measuring instruments, medical devices, and more. |

Our Advantage
Our Service
We are looking for a cooperative partner to expand our business.
Heavy-Duty Precision with Enhanced Stability
Crafted from chromium-manganese alloy steel through deep carburizing and precision grinding, it offers superior rigidity and 30% improved wear resistance. Maintains JIS C0-grade accuracy even under prolonged high-load conditions, effectively preventing positioning drift caused by temperature rise.
Optimized Circulation for High-Speed & Low-Noise
The uniquely designed reverser structure and enlarged ball channels significantly reduce ball recirculation impact. Compared to standard models, it operates 15dB quieter with 40% less vibration at high speeds, making it ideal for automation equipment requiring quiet operation.
Adjustable Preload & Easy Installation
Offers multiple preload grade options for flexible axial clearance adjustment based on application needs. The pre-assembled integrated design of the screw and nut simplifies installation, cutting on-site adjustment time by over 50%.
Long-Term Lubrication & Minimal Maintenance
The integrated oil reservoir within the nut, paired with high-performance lithium-based grease, extends maintenance intervals up to 8,000 hours under normal conditions. Special wiper seals effectively block dust and debris, ensuring reliable performance in harsh environments.
End-to-End Quality Control for Consistent Excellence
Employs full-process CNC machining and laser inspection from heat treatment to thread forming. Each screw comes with an accuracy traceability report, guaranteeing zero batch-to-batch variation and perfect interchangeability for precision drive systems.
Enhanced Environmental Adaptability
The surface undergoes specialized treatment to resist corrosion in high-humidity or chemically aggressive environments, with salt spray test endurance exceeding 500 hours. This makes it suitable for marine, offshore, and food processing applications where equipment reliability is critical.

FAQ
Q1: How to precisely adjust the axial clearance of SFU4010?
Three preload grades (Light P0, Medium P1, Heavy P2) are available, adjustable by replacing specific preload spacers. We recommend consulting our technical engineers before installation to determine the optimal configuration based on your load conditions.
Q2: What special considerations are needed for use in humid environments?
We recommend the optional anti-corrosion seal kit, featuring a double labyrinth seal structure filled with special grease, effectively blocking moisture and corrosive agents. For coastal or high-humidity applications, we offer surface passivation treatment services.
Q3: How to determine when to replace the lubricant?
Under normal conditions in a clean environment, lubricant should be replaced after 8,000 operating hours. If noise increases by over 15% or abnormal temperature rise occurs (exceeding ambient temperature by 35°C), immediately inspect lubrication status. Free original grease samples are available for testing.
Q4: What is the minimum order quantity for custom specifications?
The MOQ is 50 pieces for lengths exceeding 1200mm or special end machining. For R&D samples, we offer a "Small Batch Trial" service starting from just 5 pieces, complete with full performance test reports.
Q5: How to prevent the nut from disengaging during installation?
While SFU4010 features an internal anti-derailment design, we strongly recommend using the temporary fixing clips supplied with each order. If balls are accidentally dispersed, we provide emergency repair kits containing specific balls and assembly tools.
Q6: What should I do if slight vibration occurs during operation?
First, check the mounting parallelism of support units (should be ≤0.02mm/m) and motor coupler alignment. If issues persist, it may indicate preload mismatch. Our technical team offers remote vibration analysis services.
