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 US Manufacturers Struggle with Coaxial Gears – And How It's Costing You

As a purchasing manager in industrial automation, you face relentless pressure to optimize ROI while maintaining uptime. But sourcing coaxial gears reveals harsh realities.

High Prices: Domestic suppliers charge 50-70% premiums, eroding your margins. A standard coaxial gear reducer can cost $1,200 vs. our $650 equivalent.
Low Quality & Frequent Failures: Inferior materials lead to backlash exceeding 10 arcmin, causing 25% more downtime in CNC machines.
Skyrocketing Shipping Costs: Cross-border logistics from unreliable sources add $200-500 per order, with delays up to 8 weeks.
Lack of Customization: Off-the-shelf gears don't match your torque needs, forcing inefficient workarounds.
Supply Chain Disruptions: Competitors reliant on volatile pricing and poor service face stockouts, halting production lines.
Compliance Headaches: Gears failing US standards (RoHS, CE) risk recalls and fines up to $100K.

These issues compound: a 2025 McKinsey report notes US manufacturers lose $50B annually to gear failures. Ready to break the cycle? Contact us now.
