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.

The Hidden Costs of Inferior Bearings in Your Operations

As a purchasing manager in the U.S. manufacturing sector, you're under pressure to cut costs while maintaining uptime. But traditional carbon steel bearings fail you in harsh environments.

High Prices Eating into Margins: Premium corrosion-resistant options from U.S. suppliers cost 40-60% more, squeezing your ROI.
Low Quality Leading to Failures: Cheap imports from unreliable chains corrode within months, causing 25% unplanned downtime per industry reports.
Skyrocketing Shipping Costs: Bulky shipments from distant suppliers add $5,000+ per order, especially post-2026 tariff hikes.
Compliance Nightmares: Non-certified bearings risk FDA/USDA violations in food/pharma lines.
Slow Lead Times: 12-16 week waits disrupt your supply chain.
Limited Customization: Off-the-shelf parts don't fit OEM needs perfectly.

These issues compound: a single bearing failure can cost $10,000 in lost production. Ready for bearings that last?

Performance Characteristics: These bearings achieve ISO P6 precision, with radial runout <5μm. In salt spray tests (ASTM B117), they endure 1,000+ hours without pitting – vs. 200 hours for chrome steel. Fatigue life exceeds 10^7 cycles under 0.4C/P load (ISO 281). Operating temp: -20°C to 150°C. Low friction coefficient (μ=0.001-0.005) reduces energy use by 15%.

Application Scenarios and Case Studies

Food & Beverage: Hygienic rollers in conveyor systems prevent contamination; a U.S. dairy plant reduced failures by 70% after switching.

Pharmaceuticals: Cleanroom-compatible for tablet presses; withstands CIP cycles.

Marine & Chemical: Pumps and winches in saltwater; OEM for U.S. shipbuilders.

Medical Equipment: Surgical robots and imaging machines demand precision and sterility.

Case: A Texas food processor integrated our NJ2308SS bearings, cutting maintenance costs by 37% in 90 days. Another California pharma firm reported zero corrosion in 18 months.
