🔩 CNC Ball Screw Set – SFU2005-4-460 (EM-BKBF15)

📄 **Product Overview:

The SFU2005-4-460 Ball Screw Set** is a high-precision, industrial-grade linear motion system engineered for CNC applications that require high load capacity and minimal backlash. With a 20mm screw diameter, 5mm lead, and 460mm overall length, this screw offers excellent speed, accuracy, and efficiency in motion conversion.

Its ends are precision-machined to support BK15 (fixed) and BF15 (floating) bearing blocks — conforming to the EM-BKBF15 standard — ensuring easy integration into CNC machines, 3D printers, robotic arms, and other automation setups.

✅ Key Features:

  • 🔧 High Load Capacity: 20mm shaft diameter makes this suitable for heavy-duty CNC operations.

  • ⚙️ Low Backlash & High Accuracy: Preloaded ball nut ensures smooth, consistent movement with minimal play.

  • 🛠️ Pre-machined Ends: Ready for direct mounting with EM-BKBF15 support units—no machining needed.

  • 🧈 Smooth & Silent Operation: Recirculating ball design reduces friction and noise, even at high speeds.

  • 🔁 Long-Lasting & Durable: Hardened steel shaft and ground surfaces provide high wear resistance.

  • 💡 Universal Compatibility: Works with most CNC builds and motor configurations.

🛠️ How to Use:

  1. Install the Screw:

    • Mount the SFU2005 screw onto your CNC machine’s linear axis or gantry.

    • Attach the BK15 and BF15 support units at each end using the included locknut and circlip.

  2. Mount the Ball Nut:

    • Secure the preloaded SFU2005 ball nut to your moving table or Z-axis carriage using a nut housing or flange bracket.

  3. Connect to the Motor:

    • Use a shaft coupling to attach your stepper/servo motor to the BK15 side of the screw.

  4. Lubrication:

    • Apply high-quality grease or oil before first use and maintain lubrication regularly.

  5. Testing & Calibration:

    • Jog the axis slowly via your CNC control software to ensure smooth, backlash-free movement.

    • Check alignment and preload settings before running high-speed operations.

⚙️ Applications:

  • CNC milling machines (X, Y, Z axes)

  • Industrial 3D printers

  • Laser and plasma cutting machines

  • Robotic arms and gantries

  • Automated packaging systems

  • Z-axis lifters and actuators

  • Heavy-load linear motion systems
