NJ310 Bearing: Precision & Durability for Heavy-Duty Applications

When you need a cylindrical roller bearing that delivers unmatched performance under extreme conditions, the NJ310 bearing stands out. Designed with a 50mm inner diameter, this single-row bearing combines radial and axial load handling in applications like electric motors, machine tools, and automotive gearboxes. Built from high-grade GCr15 steel and available in P0 to P6 precision grades, our products ensure longevity even in high-temperature, high-load environments. Discover how LUOYANG INNO BEARING CO., LTD’s 30+ years of expertise translates into reliable solutions for your industrial needs.

Why Choose Our NJ310 Cylindrical Roller Bearings?

1. Engineered for Extreme Conditions

• High Load Capacity: Supports dynamic loads up to 48kN and static loads of 42kN, ideal for metallurgical machinery and port cranes.

• Heat Resistance: Stable operation at 150°C (short-term 200°C) thanks to advanced heat treatment processes.

• Customizable Designs: Choose from brass cages, stamped steel, or specialized coatings for corrosive environments.

2. Precision Manufacturing

Every NJ310 bearing undergoes rigorous grinding and testing to meet ISO standards. Our P5-grade precision reduces vibration by 30% compared to standard bearings, critical for robotics and wind turbine gearboxes.

3. Industry-Proven Durability

• Mining Equipment: Triple-lip seals and carbide-coated variants resist abrasive dust in Australian iron ore mines.
• Wind Turbines: Hybrid ceramic rollers reduce weight by 20% while meeting GL Wind and DNV-GL certifications.
• Robotics: Slim-profile NJ310-RB3 bearings save 15% space in collaborative robot joints.

  

Quality Assurance You Can Trust
