High-Preccision Left-Hand Ball Screw 1605 & 4010: The Ultimate Choice for CNC Linear Guide Modules

High-Preccision Left-Hand Ball Screw 1605 & 4010: The Ultimate Choice for CNC Linear Guide Modules

April 07, 2026

       In the realm of precision linear motion, ball screws serve as the "heart" of industrial equipment, while left-hand thread ball screws stand out for their unique directional control capabilities. As a professional manufacturer based in Nanjing, Jiangsu, China, Shuntai specializes in high-precision left-hand thread ball screws—including the 1605 and 4010 models with single flange ball nuts—tailored explicitly for CNC linear guide module applications.

Whether you are developing CNC machine tools, automated production lines, or high-precision positioning systems, our 1605/4010 left-hand ball screws, paired with single flange nuts, deliver exceptional stability, high rigidity, and seamless integration. This blog will dive deep into their features, applications, and why they are your ideal partner for linear motion solutions.

Core Features of Shuntai’s 1605/4010 Left-Hand Ball Screw with Single Flange Nut

1. Superior Material & Craftsmanship: GCr15 Bearing Steel for Longevity

 

Both 1605 and 4010 ball screw shafts are crafted from GCr15 bearing steel (HRC 58-62), a premium material renowned for its high hardness, wear resistance, and fatigue strength.
  • Rolled & Ground Processes: We offer both rolled (cost-effective, C7 precision) and ground (ultra-precise, C3-C5 precision) variants to meet diverse budget and accuracy needs.
  • Left-Hand Thread Design: Optimized for bidirectional motion control, ideal for CNC modules requiring reverse positioning or balanced load distribution.
  • Single Flange Nut: Simplifies installation with a compact, one-side flange structure, enabling rigid mounting on carriages or machine bases without additional housing requirements.
  • 2. Model-Specific Advantages: 1605 vs 4010
  • Parameter 1605 Ball Screw 4010 Ball Screw
    Shaft Diameter 16mm (medium size, space-saving) 40mm (large diameter, high rigidity)
    Lead 5mm (high precision, low speed, suitable for micro-positioning) 10mm (high speed, large thrust, ideal for heavy-load transport)
    Typical Application Small CNC equipment, 3D printers, medical devices Large CNC machining centers, automated production lines, heavy-duty logistics
    Precision Grade C5-C7 (cost-effective, high repeatability) C7-C10 (high load capacity, stable under extreme conditions)
  • 3. High Compatibility with CNC Linear Guide Modules
  • The single flange nut design ensures seamless integration with linear guide rails, creating a complete linear motion system:
     
    • The flange’s through holes allow direct bolting to guide rail carriages, reducing assembly complexity.
    • The ball screw’s left-hand thread cooperates with linear guides to suppress vibration, ensuring <0.01mm/m straightness error during high-speed operation.
    • Compatible with standard servo/stepper motors, supporting rapid customization for diverse CNC module designs.
    • Key Applications: Where Our 1605/4010 Ball Screws Shine

    • 1. CNC Machine Tools: The Backbone of Precision Machining

         CNC milling machines, lathes, and machining centers rely on ball screws for X/Y/Z axis feeding. Our 1605/4010 models:
      • Ensure micron-level positioning accuracy, critical for complex part processing.
      • Withstand high axial loads (up to 10 tons for 4010) during heavy cutting, maintaining long-term stability.
      • Left-hand thread design prevents loosening under reverse rotation, ideal for multi-axis linkage operations.

      2. Automated Production Lines: Efficient & Reliable Motion

         In automotive parts manufacturing, electronic assembly lines, and packaging machinery:
      • 4010 ball screws drive heavy-load conveyors, achieving 10mm per rotation for high-speed transport.
      • 1605 models power precision manipulators, completing micro-assembly tasks with ±0.005mm repeatability.
      • Daily global shipments (7-day delivery to Shanghai Port) ensure you never miss production deadlines.

      3. Specialized Equipment: Customized Solutions for Unique Needs

         From laser cutting machines to medical testing equipment:
      • Left-hand thread ball screws enable balanced force distribution, reducing equipment vibration and improving processing quality.
      • Custom machining per customer drawings: We adapt to non-standard sizes, flange shapes, and thread lengths to fit specialized CNC linear guide modules.
      • Why Choose Shuntai as Your Ball Screw Supplier?

    • How to Select the Right Ball Screw for Your CNC Linear Guide Module
    • Define Load & Speed: For heavy loads (>5 tons) and high speed (>1m/s), choose 4010; for small loads and micro-positioning, select 1605.
    • Determine Precision Grade: C3-C5 for ultra-precision equipment (lasers, medical devices); C7 for general CNC machines (cost-effective).
    • Check Installation Space: The single flange nut is compact—ideal for space-constrained modules. If space is limited, confirm flange size with our team.
    • Confirm Thread Direction: Left-hand thread is required for reverse positioning or balanced load; contact us to confirm your application needs.
