Cylindrical Roller Product Overview

GY specializes in manufacturing high-precision cylindrical rollers ranging from 0.5mm diameter × 1.5mm length to 6mm diameter × 40mm length, with tolerances as tight as 0.001mm. Our rollers are crafted from bearing steel, stainless steel, stainless iron, high-carbon steel, ZOCM, and custom materials to meet extreme operational demands.

 

Cylindrical Roller Core Advantages

1. Structural Excellence

  • Linear Contact Design (0° contact angle)
  • Optimized L/D Ratio (1~3)
  • Precision-Guided Ribs (single/double rib configurations)
  • Variant Options: NU/NJ/NUP types (various rib arrangements), split designs (separable inner/outer rings), and full-complement structures (cageless).

2. Performance Superiority

Performance Aspect Technical Advantage Data Metrics
Radial Load Capacity Linear stress distribution 50-70% higher than ball bearings
High-Speed Performance Low roller-to-race ratio DN value up to 1.5×10⁶
Precision Retention Rigid support structure Radial runout <2μm (P4 grade)
Friction Characteristics Pure rolling motion Coefficient: 0.001-0.003
Cost Efficiency Standardized production 30-40% lower than tapered rollers

 

3. Innovation & Technology

  • Surface Engineering: Superfinishing (Ra <0.05μm), DLC coating (45% lower friction).
  • Structural Innovation: Hollow rollers (20% weight reduction + enhanced heat dissipation), asymmetric ribs (controlled axial clearance).
  • Smart Monitoring: Embedded sensors (real-time temperature/vibration tracking), wear prediction algorithms (±5% lifespan accuracy).

4. Application Scenarios

  • High-End Equipment: CNC machine tool spindles (20,000 rpm), industrial robot RV reducers (±0.01mm positioning accuracy).
  • New Energy: Wind turbine gearboxes (10MW+), hydrogen fuel cell air compressors (corrosion-resistant variants).
  • Transportation: High-speed train traction motors (350 km/h), heavy-duty truck hubs (80-ton load capacity).
  • Extreme Environments: Cryogenic conditions (-196°C for liquid hydrogen pumps), high-vacuum aerospace mechanisms.

5. Selection Guidelines

  • Precision Grades: P5 (standard machinery), P4/P2 (precision spindles).
  • Clearance Options: C3 (high-temperature), CN (standard conditions).
  • Lubrication Solutions: Oil-air lubrication (DN >1×10⁶), solid lubrication (maintenance-free designs).
