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.

Your Biggest Challenges with Traditional Bearings in 2026

As a purchasing manager sourcing for US manufacturing lines, you face relentless pressure to cut costs while maintaining uptime. High prices from premium brands, inconsistent quality from cheap imports, and soaring shipping fees are eating into your ROI.

High Maintenance Costs: Traditional bearings require constant lubrication, leading to 20-30% downtime in linear motion systems, per IndustryWeek 2025 report.
Low Quality Failures: Inferior sintered bearings seize under load, causing 37% higher replacement rates and production halts.
Skyrocketing Shipping: Delays from China suppliers average 45 days, inflating costs by 25% amid global logistics crunch.
Unreliable Supply Chains: Competitors falter on OEM customization, leaving your automation projects stalled.
Regulatory Headaches: Non-compliant imports risk FDA/CE violations in USA markets.
Performance Gaps: Bearings can't handle high-speed linear guides without frequent failures.

Imagine slashing these pains. Explore our self-lube bearings now.
