High Light 51318 Single Direction Bearing51318 BearingPrecision Industrial Machinery Bearings
51318 Single Direction Thrust Ball Bearing
Basic Parameters
  • Bore diameter (d): 90mm
  • Outer diameter (D): 155mm
  • Thickness (T): 50mm (single bearing)
  • Type: Single-direction thrust ball bearing (51000 series)
  • Weight: Approximately 3.67-3.88kg (3.67kg for SKF models, 3.88kg for NACHI)
  • Structure: Single-row, non-separable design with flat housing washer, shaft washer, and steel balls
Core Performance Specifications
Load Capacity
  • Dynamic load rating (Cr): 182-213kN (significant brand variation)
  • Static load rating (C0r): 440-525kN (highest for NACHI models)
  • Material: GCr15/SUJ2 high-carbon chromium bearing steel (surface hardness HRC58-62)
Speed & Precision
  • Limiting speed:
    • Grease-lubricated: 1,100-1,500rpm
    • Oil-lubricated: 1,600-2,200rpm
  • Precision class: Standard P0; customizable to P4
Technical Features
  • Axial load-oriented: Only withstands unidirectional axial force
  • Low-friction design: Optimized raceway curvature and cage structure
Structural & Environmental Adaptability
  • Mounting fit:
    • Shaft: h8 (recommended tolerance)
    • Housing bore: H8
  • Temperature range:
    • Standard: -20°C to 120°C
    • High-temperature type: Up to 200°C
  • Sealing options: Open, 2RS (double rubber seals), or ZZ (double metal shields)
Typical Applications
  • Industrial Machinery: Heavy-duty presses, forging equipment, gearboxes, machine tool spindles
  • Transportation: Railway freight car axle boxes, large construction machinery
  • Precision Equipment: Medical imaging devices, food packaging machinery
Maintenance & Lubrication Guidelines
Lubrication Options
  • Grease lubrication: Lithium-based grease (NLGI Grade 2)
  • Oil lubrication: ISO VG 46-68 mineral oil
Lubrication Interval
  • Normal conditions: Every 8,000-12,000 hours
  • High-temperature/high-pollution: Shorten to 4,000 hours
Certifications & Compatibility
  • Standards compliance: ISO 9001:2015 quality management system
  • Cross-brand replacement: Interchangeable with NSK 51318, NACHI 51318, HRB 51318
Customization Options
  • Material upgrades: Ceramic hybrid bearings, stainless steel (SUS440C)
  • Special designs: Phosphating coating, laser marking for IIoT tracking
Selection Considerations
  • Load direction: Single-direction design requires paired mounting for bidirectional forces
  • Fit precision: Cylindricity error should be controlled within 0.01mm
  • Temperature compensation: Reserve 0.03-0.05mm axial expansion clearance
Summary
The 51318 thrust ball bearing features high axial load capacity (up to 525kN static) and cost-effectiveness as core advantages, making it widely used in industrial machinery, transportation, and precision equipment. Its standardized design and customizable features balance performance and cost. With scientific lubrication and maintenance, it delivers reliable long-term operation in environments ranging from -20°C to 200°C.
