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 Pain Points in Cross Roller Bearing Procurement

As a purchasing manager or technical director in the US manufacturing sector, you face relentless pressure to cut costs while maintaining precision. Here's what our clients tell us:

High Prices: Premium suppliers charge up to 40% more without proportional quality gains.
Low Quality & Failures: Inconsistent tolerances lead to downtime in robotics applications, costing thousands per incident.
Skyrocketing Shipping Costs: Delays from overseas add 25-50% to total landed costs for urgent projects.
Long Lead Times: Standard waits of 12-16 weeks disrupt your production schedules.
Limited Customization: Off-the-shelf options don't fit OEM needs for high-speed RV reducers or turntables.
Unreliable Supply Chains: Competitors falter on quality control, forcing multiple sourcing tests.

Real Scenario: A US automation firm lost $150K in Q1 2025 due to bearing failures from a low-cost Chinese supplier. Don't let this be you.
