Precision NUP Cylindrical Roller Bearings for Heavy Industrial Machinery – Custom-Built for Extreme Loads & Harsh Environments

30+ Years of Expertise in Manufacturing High-Temperature-Resistant (150°C), Large-Size (Up to φ5000mm) Bearings with 15-20 Day Fast Delivery for Custom Orders

Why NUP Cylindrical Roller Bearings Are Essential for Your Machinery

When you need a bearing that handles heavy radial and axial loads while maintaining precision in harsh environments, NUP cylindrical roller bearings deliver unmatched performance. Designed with an outer ring double rib and inner ring single rib + flat washer, these bearings excel in positioning shaft ends and high-maintenance scenarios. With over three decades of expertise, we engineer NUP bearings to withstand extreme conditions—from steel mill furnaces to port cranes—ensuring your equipment runs smoother, longer.

Engineered for Heavy-Duty Performance

Core Design Advantages

• Axial Displacement Control: Outer ring double ribs prevent roller slippage under shock loads.

• High Load Capacity: Supports radial loads up to 800kN and axial loads up to 200kN.

• Material Excellence: Made from GCr15SiMn steel (HRC 60-65 hardness) for 50% longer lifespan in abrasive environments.

Key Industries & Applications

• Metallurgy: Rolling mills requiring 150°C heat resistance.
• Port Machinery: Crane wheels needing IP69K dust/water protection.
• Medical Equipment: Low-noise (<35dB) variants for MRI machines.
