What Is a Ball Screw and How Does It Work?

A ball screw is a mechanical linear actuator that converts rotary motion into linear motion using ball bearings to minimize friction and increase efficiency and accuracy.

What Types of Ball Screws Do You Offer?

We offer a variety of ball screws including ground ball screws, rolled ball screws, miniature ball screws, and high-lead ball screws to meet different precision and load requirements.

How Do I Choose the Right Ball Screw for My Application?

Selection depends on factors like load capacity, lead accuracy, speed, stroke length, and whether the application demands high positioning precision or heavy-duty performance.

What Is the Difference Between Ground and Rolled Ball Screws?

Ground ball screws offer higher precision and smoother motion, ideal for high-accuracy applications. Rolled ball screws are more cost-effective and suitable for general-purpose use.

What Maintenance Is Required for a Ball Screw?

Regular lubrication is essential. Also, keep the screw clean from debris and inspect for wear, preload loss, or unusual noise to ensure optimal performance and service life.

Why HIWIN Linear MGN Guides Are Costing You More Than You Think

As a purchasing manager sourcing HIWIN linear MGN for CNC machines, robotics, or medical devices, you face mounting pressures. Original HIWIN parts promise precision, but at what cost?

High Prices: HIWIN MGN12H blocks retail at $50–$100 each – up 37% YoY due to supply chain disruptions, eating into your ROI.
Lead Times Delays: 8–12 weeks from Taiwan/USA distributors mean production halts and $5K+ daily downtime for mid-size factories.
High Shipping Costs: Importing to USA adds $200–500 per order, plus tariffs – your total landed cost skyrockets.
Quality Variability: Counterfeits flood Amazon/eBay, risking 20% failure rates in high-precision apps like 3D printers.
Limited Customization: OEM/ODM options are pricey and slow, locking you into standard specs.
Logistics Nightmares: Cross-border compliance (RoHS, CE) delays clearance at US ports.
