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 Conveyor Roller Bearings Are Failing You

As a purchasing manager in the USA manufacturing sector, you face relentless pressure to keep production lines running 24/7. Yet, conveyor roller bearings often become the weak link.

High Prices from Competitors: Premium brands charge up to 50% more, eroding your ROI without proportional durability.
Low Quality Leading to Downtime: Inferior bearings seize under heavy loads, causing 20-30% unplanned stops per industry reports from McKinsey.
Excessive Shipping Costs: Sourcing from distant suppliers adds 15-25% to landed costs, especially with volatile freight rates to the USA.
Inconsistent Performance: Bearings fail prematurely in dusty or high-speed environments, spiking maintenance budgets by 40% annually.
Limited Customization: Off-the-shelf options don't match your OEM conveyor specs, forcing compromises on speed and load.
Supply Chain Delays: Weeks of lead time disrupt just-in-time inventory, costing thousands in idle labor.

Imagine slashing these issues—ready to explore how?

These heavy duty conveyor roller bearings feature chrome steel construction, double-lip seals for dust protection, and grease lubrication for maintenance-free operation up to 2 years.

Performance Characteristics

Conveyor roller bearings from YIDI excel in key metrics. Our deep groove ball bearings (e.g., 6000/6200 series) offer low friction coefficients (0.001-0.003), reducing energy consumption by 15% per ASTM standards. Vibration levels stay under ISO 15242 Class 5, ensuring smooth operation at speeds up to 15,000 RPM.

Sealing technology: Triple-lip with labyrinth design blocks 99.9% of fine particles, proven in coal mining conveyors. Corrosion resistance via zinc phosphate coating withstands humid USA warehouses. Fatigue life calculated per ISO 281 exceeds 100,000 hours at 50% load.

Application Scenarios & Case Studies

Food Processing: FDA-compliant bearings in sanitary conveyors prevent contamination, handling 2-ton loads at 120m/min.

Mining & Aggregates: Heavy-duty models endure abrasive environments, reducing failures by 45% for a Texas quarry (case: 500 rollers installed, zero defects in 18 months).

Logistics Warehouses: High-speed idler bearings for Amazon-like sorters, cutting noise by 10dB and power use by 20%.

Automotive Assembly: Custom OEM for Ford lines, with eccentric locking collars for easy install.

Real-world ROI: USA client reported 35% lower total cost of ownership vs. SKF/Timken.
