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 Core Challenges with High Speed Roller Bearings

In 2026, USA manufacturers face intensifying pressure from rising operational costs. High speed roller bearings are critical for high-RPM applications like CNC spindles and electric vehicles, yet sourcing them brings headaches.

High Prices: Competitors charge 30-50% premiums due to import tariffs and middlemen, eroding your ROI.
Low Quality: Cheap imports fail prematurely, causing 25% unplanned downtime per McKinsey reports on manufacturing reliability.
High Shipping Costs: Delays from overseas add $5,000+ per shipment, disrupting just-in-time inventory.
Unreliable Supply Chains: Stockouts during peak demand lead to production halts.
Lack of Customization: Off-the-shelf bearings don't match your OEM needs for precision tolerances.
Compliance Risks: Non-USA certified products risk FDA/ RoHS violations in regulated sectors.
