Data Sheet

Full Complement Cylindrical Roller Bearings: Engineered for Extreme Loads & Durability

Full Complement Cylindrical Roller Bearings are the backbone of heavy machinery where maximum radial load capacity and compact design are non-negotiable. Unlike traditional caged bearings, these cageless variants pack 15–20% more rollers to handle extreme forces in mining, metallurgy, and port equipment. At LUOYANG INNO, we’ve refined these bearings over 30 years to withstand temperatures up to 150°C, heavy shock loads, and relentless operational cycles—ensuring your machinery runs longer with fewer replacements.

Where Full Complement Cylindrical Roller Bearings Excel?

1. Metallurgy & Mining

From blast furnace conveyors to rolling mills, our bearings endure 300kN+ radial loads and 500°C heat without lubrication failure. A steel plant in Germany reported a 40% reduction in downtime after switching to our high-temperature series.

2. Port & Crane Systems

Port crane sheaves using our full-complement bearings handle 2x more shock loads than standard designs. The open structure allows quick debris clearance, ideal for gritty environments.

3. Medical Machinery

P4-grade precision and sub-35dB operation make these bearings fit for MRI scanners and robotic surgery arms where silence is critical.

FAQs

Q1: How do your bearings handle 500°C environments?

Our carburized steel cores and graphite-rich lubricants prevent thermal expansion failures.

Q2: Can you make bearings beyond φ5000mm OD?

Yes—we've delivered φ5500mm units for tunnel boring machines. Share your specs for a feasibility check.

Q3: What's the MOQ for custom designs?

Prototypes start at 1 unit. Bulk orders (50+ units) get volume discounts.

Q4: How do you achieve P4 precision?

Precision grinding (Ra 0.1μm) and 100% laser profilometry ensure micron-level accuracy.

Q5: Do you offer IoT-enabled bearings?

Yes—embedded sensors monitor load, temperature, and vibration for predictive maintenance.
