30+ Years OEM Supplier of RU Cross Roller Bearings with P4-Grade Precision, 150°C High-Temperature Resistance, and IoT-Driven Lifecycle Support.
If you're sourcing RU Cross Roller Bearing Wholesale options for robotics, medical imaging, or heavy machinery, you need a partner who combines precision engineering with rapid delivery. At LUOYANG INNO BEARING CO., LTD, we’ve delivered over 5 million cross roller bearings globally since 1993, specializing in both standard (OD: φ80–φ800mm) and custom designs up to φ5000mm. Our bearings maintain P4-grade radial accuracy even under 100kN loads, backed by ISO 9001 and industry-specific certifications like FDA and AS9100.

RU cross roller bearings excel in applications demanding high rigidity and compact designs. Unlike conventional bearings, their X-shaped roller arrangement distributes loads evenly, making them ideal for:

| Model | OD Range | Load Capacity | Precision Grade | Temperature Range |
|---|---|---|---|---|
| RU80 | 80–150mm | 25kN/35kN | ABEC-7 (P4) | -30°C to +150°C |
| RU500 | 500–800mm | 120kN/150kN | ABEC-7 (P4) | -60°C to +150°C |
