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.

As a US operations manager, you're battling high downtime costs and unreliable parts. YIDI Motion's shaft bearing assemblies deliver OEM-grade precision from our powerful Hebei factory, slashing your maintenance expenses by up to 37%.

Common Challenges with Shaft Bearing Assemblies in US Manufacturing

You know the frustration: your production line grinds to a halt because of a failed shaft bearing assembly. Here's what corporate buyers like you face daily:

High Prices: Premium imports cost 30-50% more than necessary, eating into your ROI.
Low Quality: Inferior bearings from unreliable suppliers fail prematurely, causing $15,000+ in unplanned downtime per incident (per US Manufacturing Institute data).
High Shipping Costs: Delays from overseas add $2,000-5,000 per shipment and weeks to lead times.
Inconsistent Performance: Misaligned shafts lead to vibration, reducing machine life by 25%.
Limited Customization: Off-the-shelf parts don't fit your OEM needs, forcing expensive modifications.
Poor After-Sales: No local support means you're on your own for warranties.

These issues plague 68% of US operations managers (Deloitte 2025 Survey). Ready for a fix? Keep reading.
