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 Biggest Challenges with Standard Deep Groove Ball Bearings

As a purchasing manager in the US manufacturing sector, you're under pressure to cut costs while maintaining uptime. But off-the-shelf bearings often fall short.

High Prices: Imported generics cost 25-50% more due to middlemen—your ROI suffers on every order.
Low Quality: Inferior materials lead to 30% higher failure rates, causing unexpected downtime and $50K+ in annual repairs.
Skyrocketing Shipping Costs: Slow suppliers mean 4-6 week waits, disrupting your supply chain and inflating logistics by 20%.
Lack of Customization: No OEM/ODM options force compromises on tolerances, forcing redesigns.
Inconsistent Performance: Variable speeds and loads mismatch your high-precision needs, like in pumps or motors.
Regulatory Hurdles: Non-compliant bearings risk FDA/CE violations in USA markets.

These issues compound: a single bearing failure can halt production for hours. Ready to fix this? Scroll to our solutions.
