Introduction
High speed ball screw are the core components of precision mechanical transmission, achieving efficient and precise linear motion through rolling friction. Widely used in CNC machine tools, semiconductor equipment, industrial robots, and other fields. This product adopts high-precision grinding technology and optimized ball circulation design, enabling a maximum rotational speed of 5000 min⁻¹ and a feed speed of 2.5 m/s, while featuring low noise (sound pressure level reduced by 3-5 dB) and long service life.
product highlights
1. High Precision & Stability
Accuracy grades cover C3-C7 (JIS standard), positioning error ±0.008mm (300mm stroke).
Double-nut preloading design eliminates axial clearance and enhances rigidity (axial stiffness ≥150 N/μm).
2. High Speed & Low Friction
Lead range 5-40mm, supports high-speed operation with dynamic response time <5ms.
Contact angle optimized to 45°, transmission efficiency >90%.
3. Long Life & Durability
Made of high-carbon chromium bearing steel (GCr15), surface hardness HRC58-62, service life >20,000 hours.
Sealed design prevents dust intrusion, maintenance cycle extended to 2000 hours.
Installation Notes:
1. Ensure the screw axis is parallel to the guide rail during installation, with perpendicularity error <0.02mm/m.
2. The distance between the nut and support bearings should be ≤5 times the screw diameter to avoid resonance.
3. Inject grease (recommended NLGI 2 lithium-based grease) before the first operation.
4. Hang vertically for long-term storage to prevent self-weight deformation.

FAQ
Q: How do I select the appropriate High speed ball screw model?
A: Model selection should consider the following factors comprehensively:
Nominal Diameter: Choose based on the load (larger diameters offer higher load capacity, typically ranging from 16 - 80mm).
Lead: For high - speed scenarios, select a large lead (e.g., 30 - 40mm, supporting a feed speed of 2.5m/s); for high - precision scenarios, choose a small lead (e.g., 5 - 10mm).
Accuracy Class: JIS C3 class is suitable for precision positioning (error ±0.008mm/300mm), while C7 class is for general mechanical transmission.
Nut Type: Select round flange, cut flange, or flangeless structures according to the installation space.
Q: What is the maximum operating speed and load of the product?
A:Maximum Speed: 2.5m/s (when the lead is 30mm), which needs to be paired with a servo motor speed (up to 5000 min⁻¹) and a lubrication scheme (oil mist lubrication is recommended).
Maximum Load: Dynamic load 289kN (HTF series), static load 420kN. Specific parameters are shown in the model specification table.
Q: What factors affect the service life of ball screws? How to extend it?
A:Service life is mainly affected by load, speed, lubrication, and installation accuracy.
Tips for extending life:
① Lubricate regularly (lithium - based grease should be replenished every 2000 hours; oil mist lubrication requires continuous oil supply).
② Keep the installation environment clean (optional protection class IP54/IP65 to prevent dust intrusion).
③ Avoid axial impact loads, and ensure the distance between the nut and bearings is ≤5 times the screw diameter to reduce resonance.
