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 Thrust Washer Bearing Challenges in 2026 US Manufacturing

As a purchasing manager or operations director, you're under pressure to optimize supply chains amid rising tariffs and logistics disruptions. Thrust washer bearings, essential for handling axial loads in rotating machinery, often fall short.

High Prices from US/EU Suppliers: Premium brands charge 30-50% more, eroding your ROI without proportional performance gains.
Low-Quality Imports: Cheap alternatives fail prematurely, leading to 45% higher downtime per ASME studies—your production lines halt unexpectedly.
Skyrocketing Shipping Costs: Post-2025 global delays mean 2-4 week waits, inflating inventory holding by 25%.
Inconsistent Quality: Variations in material thickness cause vibration and wear, risking $10K+ per incident in repairs.
Limited Customization: Off-the-shelf options don't fit OEM needs, forcing expensive reworks.
Supply Chain Risks: Competitors' disruptions leave you scrambling—China's supply chain is stable yet misunderstood.

Imagine slashing these issues. Discover how YIDI Motion's thrust washer bearings solve them below.
