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 Top Challenges Sourcing Hub City Bearings for USA Operations

As a purchasing manager or operations director, you're under pressure to keep machinery running smoothly while controlling costs. But sourcing reliable Hub City Bearings – known for their robust pillow block and mounted units – often hits roadblocks.

High Prices from Traditional Suppliers: Original branded Hub City Bearings cost 40-60% more due to tariffs and middlemen, eating into your ROI.
Inconsistent Quality: Knockoff products fail prematurely, causing 25% higher downtime and emergency repairs averaging $5,000 per incident (per US Manufacturing Report 2025).
Excessive Shipping Costs & Delays: Overseas freight from non-optimized suppliers adds $2-5 per unit and 4-6 week waits, disrupting your supply chain.
Limited Customization: Standard sizes don't fit your OEM needs, forcing modifications that increase costs by 15-20%.
Poor After-Sales Support: No local warranties or quick replacements, leaving you vulnerable during peak production.
Compliance Headaches: Ensuring RoHS, CE, and FDA standards for USA import is a compliance nightmare with unreliable vendors.

These issues compound, leading to 37% average cost overruns in bearing procurement (IndustryWeek 2026 Survey). Ready to fix this? Discover our solution below.
