Product Description

Data Sheet

High-Precision Cross Roller Ring Bearings for Demanding Industrial Applications

Optimized for extreme loads, precision motion, and harsh environments – trust 30+ years of engineering expertise.

When your equipment requires unmatched rigidity and accuracy, Cross Roller Ring Bearings deliver. These annular bearings feature a seamless forged structure with crossed cylindrical rollers, enabling bidirectional load handling and near-zero deflection. At LUOYANG INNO BEARING, we specialize in customizing products for industries where failure isn't an option – from 150°C steel mills to sub-5μm precision medical scanners.

Why Our Cross Roller Ring Bearings Outperform?

✅ Heavy-Load Champions

Withstand static loads up to 200kN and dynamic loads up to 80kN, thanks to 50Mn steel raceways and GCr15 rollers.

✅ Precision Engineered

Achieve P4-grade accuracy (<0.002mm runout) through CNC grinding – ideal for CNC turntables and optical alignment systems.

✅ Fast Custom Sizes

Get non-standard bearings up to φ5000mm in 30 days (70% faster than industry averages).

FAQ

1. Can you make bearings larger than φ3000mm?

Yes! We regularly produce custom products up to φ5000mm for mining excavators.

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

We use 42CrMo alloy steel with high-temperature grease (up to 200°C) or graphite-based lubrication for extreme heat.

3. Do you provide maintenance support?

Our IoT monitoring kits predict bearing wear by analyzing vibration trends, reducing unplanned downtime by 65%.

4. What certifications do you hold?

We’re ISO 9001, ISO 14001, and ISO/TS 16949 certified, with materials traceable to mill test reports.
