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 Standard Linear Guides Fail Your Operations

As a purchasing manager sourcing for USA-based automation, you face escalating costs and unreliable performance from traditional straight linear guides. Here's what frustrates your team daily:

High Prices: Competitors charge 20-50% premiums for basic imports, eroding your ROI without matching quality.
Low Quality: Inferior materials lead to 45% failure rates within a year, per industry reports from ARC Advisory Group.
High Shipping Costs: Delays from distant suppliers add $5,000+ per order to USA ports, disrupting just-in-time manufacturing.
Limited Customization: Off-the-shelf guides can't handle curved paths in robotics or packaging, forcing costly workarounds.
Poor Service: Slow responses and no OEM/ODM support from China's fragmented supply chain leave you vulnerable.
Compliance Risks: Non-USA certified products risk FDA/CE rejection in medical or automotive apps.

Imagine downtime halting production lines—ready to end this? Discover YIDI's fix below.

Technical Specifications Table

Our custom curved rail linear guides excel in performance. Below is a sample spec table for easy integration (crawl-friendly for Google BERT).

Model Series	Curve Radius (mm)	Rail Width (mm)	Dynamic Load (N)	Static Load (N)	Max Speed (m/s)	Accuracy (mm)
CRLG-15	150-1000	15	12,500	20,000	3	±0.005
CRLG-20	200-2000	20	22,000	36,000	4	±0.008
CRLG-25	250-3000	23	33,000	57,000	5	±0.01
CRLG-35	350-5000	35	50,000	85,000	5	±0.015

Key Features Explained: These guides use recirculating ball bearings for low friction (μ<0.003), enabling smooth curved paths. Custom options include stainless steel for cleanrooms, integrated sensors for Industry 4.0, and preloads (light/medium/heavy) for vibration resistance. Tested per ISO 9001, they handle moments Mx/My/Mz up to 200Nm.

Application Scenarios & Case Studies

Robotics: Curved rail linear guides enable 360° arm sweeps in pick-and-place robots, reducing cycle times by 25%.

Packaging Machines: Follow bottle contours for labeling, boosting throughput 40% vs. straight alternatives.

CNC & Automotive: Precision curved interpolation for door panel machining.

Medical Devices: CT scanners with arc motion for patient imaging.
