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.

Custom Gear and Rack Systems: Precision OEM Solutions for USA Industrial Automation – Cut Costs by 30% in 90 Days, Free Samples Available

Struggling with unreliable gear and rack components driving up downtime and costs? YIDI Motion delivers custom gear and rack engineered for high-precision linear motion, tailored for purchasing managers and operations leads in the USA manufacturing sector.

The Hidden Costs Plaguing Your Gear and Rack Operations

As a purchasing manager in USA industrial manufacturing, you face relentless pressure to optimize custom gear and rack systems for automation lines. But standard suppliers fall short.

High Prices Eating into ROI: Domestic gear rack systems cost 40-60% more, per AGMA reports, without proportional quality gains.
Low Quality Leading to Failures: Inferior materials cause 25% higher breakdown rates in linear motion applications, spiking maintenance by $15K/year per machine.
Skyrocketing Shipping Costs: Cross-border delays from unreliable China's supply chain add 15-20% to landed costs and 4-6 week waits.
Lack of Customization: Off-the-shelf racks don't match your CNC or robotic precision needs, forcing costly modifications.
Poor Service Response: Competitors lag on OEM/ODM requests, leaving you scrambling during production peaks.
Regulatory Compliance Headaches: Non-compliant parts risk FDA/CE fines in USA markets.

These issues compound: a single rack failure can halt assembly lines for 48 hours, costing $50K+ in lost output.
