Product Description

Precision NUP Cylindrical Roller Bearings for Heavy Industrial Machinery

Custom-Built for Extreme Loads & Harsh Environments

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 plus flat washer, these roller bearing units 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 and longer.

Technical Specifications

Parameter Range / Detail
Inner Diameter (ID) 20mm – 500mm
Outer Diameter (OD) 47mm – 1000mm (up to φ5000mm custom)
Width 14mm – 200mm
Temperature Range -30°C to +150°C

Key Advantages

  • Axial Displacement Control: Outer ring double ribs prevent roller slippage under severe shock loads.
  • High Load Capacity: Supports radial loads up to 800kN and axial loads up to 200kN in demanding bearing applications.
  • Rapid Customization: Non-standard NUP cylindrical roller bearing sizes up to φ5000mm delivered in 15-20 days.

Industry-Proven Applications

  • Port Cranes: NUP bearings reduce axial displacement by 40% in crane wheels under heavy 200kN axial loads.
  • Steel Mills: High-purity steel roller bearing construction resists micro-cracking in 150°C rolling mills.
  • Medical Equipment: Low-noise (<35dB) precision bearing variants ensure stable MRI performance.

Quality & Lifecycle Support

Every bearing undergoes 3-stage inspections, including raw material spectroscopy and final vibration testing. We provide 48-hour global dispatch for 1,000+ standard models and IoT-enabled predictive maintenance solutions.

FAQs

Q: Can you make NUP bearings for φ3000mm mining conveyors?
A: Yes! We deliver non-standard bearing sizes up to φ5000mm in 15-20 days.

Q: How do you ensure low noise in medical-grade roller bearing products?
A: Precision grinding (P4 grade) and rigorous vibration testing ensure <35dB operation.

Q: What’s the MOQ for custom NUP cylindrical roller bearing orders?
A: No strict MOX—we serve everything from single-unit prototypes to bulk bearing orders.
