Product Description

Double Row Cylindrical Roller Bearings for Extreme Load & High-Temperature Applications

When your machinery faces relentless radial loads, extreme temperatures, or harsh industrial environments, double row cylindrical roller bearings deliver unmatched performance. Engineered with two parallel rows of cylindrical rollers, these bearings provide 1.8–2.2x higher radial load capacity than single-row designs, making them ideal for steel mills, mining crushers, and heavy-duty port cranes. At LUOYANG INNO BEARING, we specialize in custom roller bearing solutions up to φ5000mm, combining 30+ years of expertise with fast-track delivery in 15–20 days.

FAQs

Q: How do your double row cylindrical roller bearings handle 150°C+ temperatures in steel mills?
A: We use nitrided steel cages and high-purity alloys that resist thermal expansion, ensuring bearing stability under extreme heat.

Q: Can you make bearings larger than φ5000mm?
A: Yes! Our in-house team designs mega-sized roller bearing units with impact-resistant rollers for heavy machinery.

Q: Do you offer IoT-enabled cylindrical roller bearing maintenance?
A: Absolutely. Our smart sensors monitor vibration and temperature to protect your bearing infrastructure.
