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.

The Hidden Costs Plaguing Your Linear Motion Systems

As a US-based operations manager, you're under pressure to optimize automation lines for 2026 production targets. But traditional suppliers create roadblocks.

High Prices: Western direct drive linear stages cost 40-60% more than needed, eroding your ROI amid rising tariffs.
Low Quality & Backlash: Inferior stages suffer 5-10μm repeatability errors, causing defects in semiconductor or photonics apps.
Skyrocketing Shipping Costs: Global disruptions add $5,000+ per unit from Europe/Asia delays.
Long Lead Times: 12-16 weeks wait disrupts your schedules.
Limited Customization: Off-the-shelf OEM options ignore your unique specs.
Ongoing Maintenance: Ball screw wear demands frequent downtime.

Result? 37% average cost overrun per IndustryWeek reports. Imagine slashing that today.
