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 Vertical Shaft Bearing Pain Points: Why Standard Options Fail US Operations

As a purchasing manager in the USA, you face relentless pressure to minimize downtime in vertical shaft applications like centrifugal pumps, wind turbine generators, and elevator systems. But high prices, inconsistent quality, and soaring shipping costs from unreliable suppliers are eroding your ROI.

High Prices Eating Margins: Imported bearings often cost 30-50% more than promised, with hidden tariffs pushing total expenses over budget. Scenario: A Midwest pump manufacturer reported $150K annual overages from premium-branded imports.
Low Quality Leading to Failures: Inferior materials cause premature wear—up to 37% higher failure rates in vertical shafts under axial loads, per SKF industry benchmarks. Your teams spend weeks on unplanned repairs.
High Shipping Costs & Delays: Cross-Pacific logistics from non-optimized suppliers add $5K+ per order and 4-6 week waits, disrupting just-in-time inventory for US factories.
Customization Gaps: Off-the-shelf bearings lack precision for high-speed vertical shafts (e.g., 5000+ RPM), leading to vibration and misalignment.
Regulatory Compliance Risks: Non-CE/RoHS certified parts risk FDA/USDA violations in food processing pumps, inviting fines up to $250K.
After-Sales Nightmares: No local support means months for warranties, amplifying total ownership costs by 25%.
