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 Lightweight Bearings Are Your 2026 Must-Have: Tackling Real-World Challenges

In the fast-evolving US manufacturing landscape, lightweight bearings aren't a luxury—they're essential for staying competitive. Heavy components drive up your logistics bills and slow down assembly lines.

Pain Point 1: Skyrocketing Shipping Costs – Standard steel bearings add 20-30% to freight from Asia to USA ports, eating into your margins. Scenario: A Midwest robotics firm faced $15K extra per container last quarter.
Pain Point 2: Quality Failures Under Load – Inferior imports crack under high-speed ops, leading to 15% downtime. Data: US Bureau of Labor stats show bearing failures cost manufacturers $10B annually.
Pain Point 3: High Upfront Prices – Premium US suppliers charge 2x more, delaying ROI on automation upgrades.
Pain Point 4: Supply Chain Delays – Competitors' lead times stretch to 12 weeks, missing your production deadlines.
Pain Point 5: Overweight Designs – Extra weight reduces drone/AGV efficiency by 25%, per IEEE Robotics reports.
Pain Point 6: Limited Customization – Off-the-shelf options don't fit OEM needs, forcing redesigns.
