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 Standard Spherical Bearing Sizes Fail Your Operations

As a purchasing manager in the US manufacturing sector, you face relentless pressure to optimize ROI. Yet, sourcing the right spherical bearing size often leads to frustration.

High Prices: Imported bearings from competitors cost 30-50% more due to markups, squeezing your budgets. In 2025, US firms reported average bearing costs rising 22% YoY (Statista Industrial Report).
Low Quality: Inferior materials cause premature wear—up to 60% failure rate in high-load apps, per SKF reliability studies. Your downtime skyrockets.
High Shipping Costs: Delays from China average 45 days to US ports, plus tariffs inflating fees by 25%. Expedited options? Another 40% premium.
Mismatched Dimensions: Non-standard spherical plain bearing sizes lead to misalignment, vibration, and 37% efficiency loss in linear motion systems.
Limited Customization: Off-the-shelf options ignore your OEM needs, forcing redesigns that add 2-3 months to projects.
Poor After-Sales: No local support means troubleshooting falls on your team, costing $5K+ per incident (Gartner Supply Chain Data).
