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.

Your Biggest Challenges with Mounted Bearings in USA Operations

As a purchasing manager or operations lead in the USA, you face relentless pressure to keep production lines running without interruptions. But subpar mounted steel ball bearing with cast iron housing options from competitors lead to costly headaches.

High Prices: Premium brands charge 40-60% more, squeezing your ROI in competitive markets like manufacturing and agriculture.
Low Quality: Cheap imports fail prematurely, causing 25% unplanned downtime per industry reports from McKinsey.
High Shipping Costs: Slow delivery from distant suppliers adds $500-2000 per order, delaying your projects.
Inconsistent Performance: Weak housings crack under vibration, leading to frequent replacements.
Compliance Issues: Non-USA certified units risk regulatory fines in OSHA-regulated environments.
Poor Customization: Off-the-shelf sizes don't fit your OEM needs, forcing expensive adaptations.

These issues compound, with 37% of USA manufacturers reporting bearing-related losses over $10K annually (Deloitte 2025 Survey). Ready to fix this? Discover YIDI's solution below.

Technical Specifications & Performance of Mounted Steel Ball Bearings with Cast Iron Housing

Technical details form the backbone of reliable performance. YIDI's mounted steel ball bearing with cast iron housing (pillow block and flanged types) feature high-grade GCr15 steel balls, cast iron (HT200) housings for superior vibration damping, and UC/UK insert bearings with set screw locking. These excel in heavy duty applications like conveyors, fans, and agricultural equipment.

Key Performance Characteristics:

Load Capacity: Dynamic up to 50kN, static 30kN – 20% higher than standard due to optimized ball circuits.
Speed Rating: Up to 8,500 RPM greased; corrosion-resistant grease extends life by 40%.
Temperature Range: -20°C to +120°C; optional high-temp seals for 180°C.
Lubrication: Relubrication ports standard; lithium-based grease NLGI 2.
Sealing: Triple-lip contact seals prevent 99% contaminant ingress (IP65 equivalent).
Vibration Resistance: Cast iron housing absorbs 30% more shock than pressed steel.
Shaft Fit: h6 tolerance for precise alignment, reducing misalignment wear by 25%.
