51422 M Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 51422 | The basic bearing designation, indicating a metric series thrust ball bearing. |
| M | Signifies that the bearing is manufactured from copper-alloy (brass) cage material. This provides high strength and excellent performance under high-speed and high-temperature conditions. |
51422 M Bearing Structural Features & Performance Benefits
High Axial Load Capacity: The 51422 M is designed specifically to handle significant thrust loads, with a high axial dynamic load rating of 92250 lbf and an even greater axial static load rating of 274500 lbf. This makes it ideal for applications with heavy unidirectional axial forces.
Robust Construction: The use of 52100 Chrome Steel for the bearing rings and balls ensures high hardness and wear resistance. The stainless steel cage (M designation) offers superior corrosion resistance and mechanical strength, contributing to stable operation and extended bearing life.
Precision and Stability: The bearing features tight dimensional tolerances on the bore, outside diameter, and width, ensuring a precise fit and reliable performance in the assembly. The specified chamfer dimension facilitates easier installation.
Performance Limits: With a limiting speed of 1300 rpm and an operating temperature range of -30°C to 110°C, this bearing is suited for a wide array of industrial applications.
51422 M Bearing Typical Application Areas
The 51422 M thrust ball bearing is ideally suited for heavy-duty machinery and equipment where substantial unidirectional axial loads are present. Key application areas include:
- Heavy-Duty Industrial Gearboxes
- Vertical Pumps and Compressors
- Cranes and Hoisting Equipment
- Machine Tool Tables and Screws
- Marine Propulsion Systems
