Product Description

Data Sheet

High-Load Full Complement Roller Bearings Engineered for Extreme Industrial Demands

Customizable solutions with φ5000mm+ capacity, built for metallurgy, mining, and construction machinery.

product-750-750

What Makes Full Complement Roller Bearings Ideal for Heavy-Duty Applications?

Full complement roller bearings are designed to maximize load capacity by eliminating the cage structure, allowing more rollers to fit within the same space. This makes them perfect for low-speed, high-load scenarios like crane wheels, mining equipment, and port machinery. At LUOYANG INNO BEARING, we engineer these bearings with high-purity steel and precision grinding to handle radial loads up to 1,500 kN while resisting wear in abrasive environments.

FAQs: Your Questions, Answered

1. How do your bearings handle 500°C environments?

We use chromium-molybdenum steel and graphite-enriched lubrication to minimize heat degradation.

2. What’s the lead time for a φ3000mm custom bearing?

15–20 days via our modular production system—30% faster than competitors.

3. Can these bearings handle combined axial/radial loads?

Yes! Spacer blocks and optimized roller alignment improve multi-directional load capacity.

4. Are certifications available?

We’re ISO 9001-certified and comply with CE, API, and GOST standards.

5. Do you support legacy equipment retrofits?

Absolutely. Send your old bearing specs, and we’ll reverse-engineer a compatible solution.
