Product Description

Double Row Full Complement Cylindrical Roller Bearings

When heavy machinery faces extreme loads, temperatures, or harsh environments, double row full complement cylindrical roller bearings deliver unmatched reliability. Engineered without cages to maximize roller density, these bearings offer 30% higher radial load capacity than standard designs, making them ideal for mining equipment, port cranes, and medical imaging systems. With 30+ years of expertise, LUOYANG INNO BEARING CO., LTD specializes in customizing roller bearing solutions that outperform in the toughest conditions.

Technical Specifications

Parameter Specification
Design Double-row rollers, full complement (no cage), intermediate spacer ring
Load Capacity 1.3–1.5x higher radial load capacity than standard double-row bearings

Key Advantages

  • Full Roller Complement: 25% better load distribution for longer bearing service life.
  • Proven Heat Resistance: Carburizing extends roller bearing lifespan in high-temperature environments.
  • Rapid Customization: Non-standard double row full complement cylindrical roller bearings (φ5000mm+) delivered in 25-30 days.

Industry-Proven Applications

  • Heavy Industry & Metallurgy: Withstand 150°C+ temperatures and heavy shock loads in rolling mill bearing setups.
  • Port Machinery: Multi-layer anti-corrosion coatings resist saltwater and absorb high-frequency shocks in crane slewing rings.
  • Medical Imaging: Operate below 35dB noise with zero particle emission in cylindrical roller bearing assemblies for MRI/PET-CT gantries.

Quality & Logistics

Every bearing undergoes 3-stage quality inspections to guarantee 99.9% defect-free performance. We maintain 1,000+ standard roller bearing models in global warehouses for 48-hour shipment.

FAQs

Q: Can you make bearings larger than φ5000mm?
A: Yes! Our modular production system handles custom double row full complement cylindrical roller bearings up to φ5000mm+ with a 25-30 day lead time.

Q: How do you ensure corrosion resistance in port bearing environments?
A: We apply multi-layer anti-corrosion coatings tested to IP67 standards on all external roller bearing surfaces.

Q: What's the minimum order quantity for custom bearing designs?
A: MOQ starts at 10 units for custom designs, while standard bearings ship within 48 hours.
