Description
51224 Flat Thrust Bearing High Precision Axial Load Ball Bearing
Product Overview

The 51224 Thrust Ball Bearing is a high-precision axial load solution designed for demanding industrial applications.

Basic Parameters
  • Bore diameter (d): 120mm
  • Outer diameter (D): 170mm
  • Thickness (T): 39mm (single bearing)
  • Type: Single-direction thrust ball bearing (51000 series)
  • Weight: Approximately 3.58kg (e.g., NSK 51224)
  • Structure: Single-row, non-separable design with flat housing washer, shaft washer, and steel balls
Core Performance Specifications
Load Capacity
  • Dynamic load rating (Cr): 141-154kN (varies by brand)
  • Static load rating (C0r): 430-470kN (NACHI models reach 470kN)
  • Material: GCr15/SUJ2 high-carbon chromium bearing steel (surface hardness HRC58-62)
Speed & Precision
  • Limiting speed: 1,200rpm (grease-lubricated), 1,800rpm (oil-lubricated)
  • Precision class: Standard P0; customizable to P4 for precision equipment
Technical Features
  • Axial load-oriented: Withstands unidirectional axial force only
  • Low-friction design: Optimized raceway curvature and cage structure
Structural & Environmental Adaptability
  • Mounting fit: Shaft: h8, Housing bore: H8
  • Temperature range: Standard: -20°C to 120°C, High-temperature: up to 200°C
  • Sealing options: Open, 2RS (double rubber seals), or ZZ (double metal shields)
Typical Applications
  • Industrial Machinery: Presses, forging equipment, gearboxes, machine tool spindles
  • Transportation: Automotive clutch release bearings, railway freight car axle boxes
  • Precision Equipment: Medical devices, food packaging machinery
Maintenance & Lubrication Guidelines
  • Lubrication options: Grease lubrication (lithium-based) or oil lubrication (ISO VG 46-68)
  • Lubrication interval: Normal: 8,000-12,000 hours, High-temperature: 4,000 hours
Certifications & Compatibility
  • Standards compliance: ISO 9001:2015 quality management system, CE-certified models available
  • Cross-brand replacement: Interchangeable with NSK 51224, NACHI 51224, HRB 51224
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: Control cylindricity error within 0.01mm
  • Temperature compensation: Reserve 0.03-0.05mm axial expansion clearance
Summary

The 51224 thrust ball bearing features high axial load capacity (up to 470kN static) and cost-effectiveness, making it widely used in industrial machinery, transportation, and precision equipment. With scientific lubrication and maintenance, it delivers reliable long-term operation in environments ranging from -20°C to 200°C.
