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.

Precision Rack and Spur Gear for Industrial Automation – OEM/ODM, High-Speed Delivery from China's Leading Factory

Struggling with unreliable rack and spur gear that cause downtime in your CNC machines or robotics? YIDI Motion delivers custom precision solutions tailored for US manufacturers, slashing costs by up to 37% while ensuring AGMA quality standards.

Your Core Pain Points with Rack and Spur Gear Sourcing

As a purchasing manager in the US manufacturing sector, you're under pressure to optimize linear motion systems for 2026 automation demands. But traditional suppliers fall short.

High Prices: US/EU vendors charge 40-60% premiums for standard rack and spur gear, eroding your ROI. Industry data shows average costs at $150/meter vs. our $90/meter equivalent.
Low Quality: Cheap imports from unregulated sources fail prematurely – backlash exceeds 0.1mm, leading to 25% machine downtime per ASTM standards.
High Shipping Costs: Overseas delays add $500+ per order and 4-6 weeks wait, disrupting your just-in-time inventory.
Limited Customization: Off-the-shelf spur gear racks don't match your CNC or robotic specs, forcing expensive modifications.
Unreliable Supply Chain: Competitors' disruptions (e.g., post-2026 tariffs) mean stockouts during peak seasons.
Compliance Headaches: Gears lacking RoHS/CE certs risk FDA/USDA violations in food/pharma apps.

These issues cost US firms $2.3B annually in motion control failures (per McKinsey 2025 report). Ready for a fix?
