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.

Struggling with Unreliable Bearings? Here's What American Manufacturers Face Daily

As a purchasing manager in the USA, you know the frustration of bearings that don't deliver. High prices from premium brands, inconsistent quality from cheap imports, and shipping delays that halt production lines.

High Costs: Premium F206 bearings can cost 40-60% more, eating into your ROI without proportional performance gains.
Low Quality Failures: Inferior materials lead to premature wear, with failure rates up to 25% higher per industry reports from ABMA (American Bearing Manufacturers Association).
Skyrocketing Shipping: Overseas suppliers charge $500+ per pallet to USA ports, plus weeks of wait time disrupting your supply chain.
Inconsistent Specs: Variations in tolerances cause vibration and misalignment in machinery like conveyors and pumps.
No Customization: Off-the-shelf options ignore your OEM needs, forcing compromises on design.
Poor After-Sales: No local support means downtime costs averaging $50K per incident (per Deloitte manufacturing study).

These issues compound, leading to 37% higher operational costs for affected firms. Ready for a better option? Discover YIDI's solution below.
