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 Standard Bearings Fail Your US Operations: 5 Critical Pain Points

As a US operations manager, you're dealing with high prices from premium brands, low quality from unverified suppliers, and soaring shipping costs that erode ROI.

High Acquisition Costs: Off-the-shelf angular contact bearings from competitors cost 40-60% more due to import tariffs and middlemen markups.
Inconsistent Quality: Generic imports fail prematurely, causing 37% higher downtime in high-speed spindles (per SKF industry reports).
Prohibitive Shipping Delays: Lead times stretch to 12+ weeks from Europe/Asia, disrupting your production schedules.
Lack of Customization: Standard designs can't handle your specific axial/radial load ratios, leading to vibration and reduced lifespan.
Regulatory Compliance Gaps: Non-US certified bearings risk FDA/CE non-compliance in precision machinery.

These issues inflate your total cost of ownership by up to 50%. Discover how YIDI fixes this – scroll down.
