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 Plane Bearings Are Costing You More Than You Think

As a purchasing manager or operations director in US manufacturing, you face relentless pressure to optimize ROI. But subpar plane bearings—also known as plain or sleeve bearings—create hidden drags on your efficiency.

High Prices from Competitors: Traditional suppliers charge 20-40% premiums due to middlemen, inflating your BOM without value.
Low Quality Leading to Failures: Inferior materials cause 37% higher failure rates (per industry reports from ABMA), triggering unplanned downtime costing $50K+ per incident.
Excessive Shipping Costs: Overseas sourcing without optimized chains means $15-30 per unit in freight, eroding margins in volatile 2026 supply markets.
Inconsistent Performance: Variable friction coefficients lead to uneven wear, reducing machine lifespan by 25% and demanding frequent replacements.
Lack of Customization: Off-the-shelf options don't fit OEM needs, forcing compromises in high-precision linear motion applications.
Supply Chain Delays: Lead times averaging 8-12 weeks disrupt your just-in-time operations.
