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 Mounted Plain Bearings

As a US operations manager, you face relentless pressure to keep production humming. But subpar mounted plain bearings – those simple yet critical components supporting rotary and linear loads – often derail your goals.

High Prices Eating into ROI: Premium US suppliers charge up to 50% more, squeezing your budgets without proportional quality gains.
Low-Quality Failures: Inferior materials lead to premature wear, with failure rates hitting 25% within the first year, per industry reports from ABMA.
Skyrocketing Shipping Costs: Delays from global sourcing add $5-10K per order in freight, plus weeks of wait time disrupting your supply chain.
Inconsistent Quality from China Suppliers: Many lack rigorous testing, causing vibration issues and 37% higher downtime in heavy machinery.
Limited Customization: Off-the-shelf options don't fit your OEM needs, forcing expensive modifications.
After-Sales Headaches: No reliable support means you're stuck replacing parts solo. Ready for a fix?
