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.

Core Pain Points in Roller Bearing Rail Procurement for USA Buyers

As a purchasing manager in industrial manufacturing, you're under pressure to source roller bearing rails that handle extreme loads without failing. But common issues persist:

High Prices: Premium brands charge 30-50% more, eroding your ROI on automation projects.
Low Quality & Failures: Inferior rails from unverified suppliers lead to 37% higher downtime, per IndustryWeek reports.
Skyrocketing Shipping Costs: Middlemen inflate logistics to USA by 25%, delaying projects by weeks.
Inconsistent Supply Chains: China's fragmented suppliers cause stockouts, forcing rushed orders at premium rates.
Lack of Customization: Off-the-shelf rails don't match your heavy-duty needs, like CNC machines or pallet systems.
Compliance Headaches: Non-USA certified products risk FDA/CE violations in regulated sectors.

These frustrations cost operations managers an average of $150K annually in inefficiencies. Discover how YIDI Motion fixes this below.

Performance Characteristics (One-Third Focus)

Roller bearing rails excel in heavy load capacity applications due to cylindrical rollers distributing force evenly, unlike ball guides. Expect 4-5x higher rigidity and 50% less deflection under 50kN loads. Friction coefficient: 0.002-0.003, enabling smooth high-speed ops up to 3m/s.

Key metrics:

Moment Load Resistance: Up to 400Nm in pitch/yaw/roll – ideal for multi-axis robots.
Travel Life: 50,000km at 1m/s, per ISO calculations.
Temperature Range: -20°C to +80°C, with seals for dust-proof IP65 rating.
Low Noise: <60dB, smoother than recirculating ball types.

Application scenarios:

CNC Machining Centers: YD-RG35 handles 97kN for spindle gantries.
Automated Warehousing: Pallet shuttles with 100kN static loads.
Heavy Machinery: Injection molding, printing presses in USA factories.
Case Study: Michigan auto supplier reduced rail failures by 45% after switching to our YD-RG45, saving $80K/year.
