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

As a purchasing manager in the US manufacturing sector, you're under pressure to optimize supply chains while battling rising costs. Plastic bearings promise lightweight solutions, but subpar suppliers lead to failures.

High Prices: Premium plastic bearings from competitors cost 40-60% more due to inefficient China's supply chains.
Low Quality: Inferior materials cause 25% failure rates within the first year, per industry reports from ABMA.
High Shipping Costs: Delays from overseas add $5K+ per order, disrupting your production lines.
Corrosion & Maintenance: Metal bearings rust in humid factories, demanding frequent lubrication—up to 20 hours/week per machine.
Limited Customization: Off-the-shelf options don't fit OEM needs, forcing redesigns.
Slow Delivery: 8-12 week lead times from competitors halt your projects.

These issues erode ROI. Imagine slashing them with a reliable partner. Discover how below.
