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.

Overcoming Key Pain Points in High-Load Linear Motion

As a purchasing manager in the USA manufacturing sector, you face relentless pressure to cut costs while maintaining precision. But high prices from premium brands, inconsistent quality from overseas suppliers, and soaring shipping fees are derailing your ROI.

High Prices: Traditional ball screw actuators cost up to 40% more without proportional performance gains.
Low Quality: Inferior rollers lead to premature wear—one study shows 25% failure rates within 10,000 cycles.
High Shipping Costs: Delays from China average 6-8 weeks, inflating logistics by 15-20%.
Customization Gaps: Off-the-shelf options don't match your OEM needs, forcing expensive modifications.
Precision Loss Under Load: Backlash exceeds 50 microns, compromising CNC and robotic accuracy.
Supply Chain Disruptions: Competitors' lead times stretch to 12 weeks amid global shortages.

These issues result in 37% higher downtime for your operations. Ready to fix them? Explore our solution below.

YIDI Motion's Planetary Roller Screw Actuator: Engineered for Superior Performance

Our planetary roller screw actuators use a patented roller recirculation system, where multiple planetary rollers orbit between the screw and nut, distributing loads evenly for 5x the rigidity of ball screws. Ideal for high-force applications like injection molding, aerospace actuators, and heavy-duty robotics.

Core Advantages

Powerful Factory Backing: 100+ employees, 30% senior technicians, German/Japanese equipment for zero-defect production.
Quality Assurance: Rigorous testing exceeds ISO 9001 standards—99.9% uptime in field trials.
OEM/ODM Design: Fully custom diameters from 20-120mm, leads 2-20mm, tailored to your specs.
High-Speed Delivery: USA stock ready in 3-5 days; custom orders ship in 2 weeks vs. competitors' 8+.
Load Mastery: Up to 500kN dynamic load—perfect for high precision planetary roller screw actuator needs.
Energy Efficiency: 20% lower power draw due to low friction coefficients (μ < 0.001).

This table highlights why our actuators excel in planetary roller screw actuator manufacturer benchmarks. The roller design minimizes slip (zero backlash), accelerates to 100m/min smoothly, and handles shock loads 3x better than planetary ball variants.

Application Scenarios and Case Studies

In a recent USA automotive project, a Michigan Tier-1 supplier integrated our 80mm actuator into press lines. Result: 45% faster cycle times, reducing energy by 28%. Another aerospace client in California achieved 1-micron positioning for satellite assembly.

Industrial Automation: Pick-and-place robots (loads >200kN).
Machine Tools: CNC mills with high axial forces.
Medical Equipment: Surgical robots requiring zero backlash.
Renewable Energy: Solar tracker actuators enduring harsh weather.

Technical deep dive: The planetary arrangement—12-24 rollers per circuit—ensures 100% contact, yielding efficiencies >90%. Friction torque is just 1/10th of sliding screws, extending MTBF to 100,000 hours. For custom planetary roller screw actuator needs, we simulate via SolidWorks and FEA before prototyping.
