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.

Why Your Current Circular Linear Guides Are Costing You Dearly

In high-stakes manufacturing, unreliable linear motion components disrupt everything. Here's what US purchasing managers face daily:

High Prices Without ROI: Competitors charge premiums for circular linear guides that underperform, inflating your CAPEX by 25-40% per Gartner reports.
Low Quality & Frequent Failures: Inferior materials cause 50% higher downtime, as seen in 2025 AME surveys—your production lines halt unexpectedly.
Skyrocketing Shipping Costs: Delays from fragmented China supply chains add $5K+ per order in logistics, per Freightos data.
Lack of Customization: Off-the-shelf guides don't fit OEM needs, forcing redesigns and wasting engineering hours.
Poor After-Sales Support: No local compliance or quick spares, risking FDA/CE violations in US ops.
Slow Delivery Times: 8-12 week waits kill project timelines.
