🔩 CNC Ball Screw Set – SFU2005-4-460 (EM-BKBF17)

📌 Product Description:

The SFU2005-4-460 Ball Screw Set is a high-precision linear motion system engineered for CNC machines, 3D printers, and industrial automation. With a screw diameter of 20mm, lead of 5mm, and an overall length of 460mm, this model delivers excellent performance for medium to high-load applications.

The screw is pre-machined to EM-BKBF17 standards, meaning it's fully compatible with BK17 (fixed) and BF17 (floating) bearing blocks. It includes a preloaded SFU2005 ball nut, reducing backlash and ensuring smooth, accurate motion. This model is ideal for CNC axes where moderate length and high precision are required — such as X, Y, or Z axes.

📐 Technical Specifications:

✅ Key Features:

• High-Precision Linear Motion: C7 grade precision for reliable positioning and repeatability.

• Preloaded Ball Nut: Minimizes axial play and improves machining accuracy.

• EM-BKBF17 Machined Ends: Ready-to-use with BK17/BF17 support blocks — no machining required.

• Durable & Long-Lasting: Constructed from chrome-plated hardened alloy steel for wear resistance and longevity.

• Low Friction & Noise: Recirculating ball design ensures smooth, quiet operation, ideal for CNC environments.

• High Load Capacity: 20mm shaft diameter supports medium to heavy-duty applications.

🛠️ How to Use:

1. Mount the Ball Screw:

   • Install the ball screw onto your CNC frame or guide rail system.

   • Fit the BK17 (fixed) and BF17 (floating) bearing blocks to each end.

2. Install the Ball Nut:

   • Attach the preloaded ball nut to your machine's moving axis using a compatible nut bracket or flange housing.

3. Connect Motor:

   • Attach your stepper or servo motor via coupling on the BK17 side.

4. Apply Lubrication:

   • Add grease or oil to the ball nut and screw track for smoother operation and extended lifespan.

5. Test & Calibrate:

   • Run the axis through your CNC controller to test for backlash, accuracy, and smooth motion. Adjust alignment as needed.

⚙️ Applications:

• CNC milling, engraving, or routing machines

• Z-axis or gantry movement systems

• 3D printer linear drives

• Laser cutting or pick-and-place machines

• Industrial robotic arms or lift tables

• Precision automation and packaging lines
