nn3020 bearing

NN3020 Bearing High-Temperature Heavy-Load for Extreme Industrial Environments

When your machinery operates under intense heat, heavy loads, or corrosive conditions, the NN3020 bearing delivers unmatched durability and precision. Designed for industries like metallurgy, mining, and port machinery, this double-row cylindrical roller bearing combines a 100mm inner diameter with advanced heat-treated materials to withstand temperatures up to 500°C and dynamic loads exceeding 300kN. Backed by 30+ years of engineering expertise, our bearings ensure 99.9% defect-free performance, making them the go-to choice for reducing unplanned downtime.

Why Choose Us?

🔸 Extreme Environment Performance

Engineered for continuous operation in temperatures ranging from -30°C to 150°C, the NN3020 uses GCr15SiMn steel and zirconia-coated cages to resist thermal expansion and corrosion.

🔸 Heavy-Load Optimization

With a dynamic load capacity of 320kN (30% higher than standard bearings), it's ideal for metallurgical kilns, crushers, and cranes requiring impact resistance.

🔸 Fast Customization & Delivery

Need oversized dimensions (up to φ2000mm) or specialized materials? Our modular production system delivers non-standard designs in 15–20 days.

🔸 Proven Reliability

Rigorous ISO 15242 vibration testing and accelerated lifespan trials ensure 50,000+ hours of operation in abrasive environments.

Technical Specifications

Customizable sealing (IP68), lubrication (solid oil/grease), and cage materials (brass/stamped steel).

Where the NN3020 Excels?

🔥 Metallurgical Kilns
