51426 M Bearing Product Overview & Core Advantages
The 51426 M is a metric thrust ball bearing engineered for applications demanding high axial load capacity and precision. Its design is optimized to accommodate heavy thrust loads in a single direction, making it an ideal choice for scenarios requiring robust support against axial forces. Manufactured from high-grade 52100 Chrome Steel for both rings and balls, and featuring a stainless steel cage, this bearing ensures excellent durability and reliable performance in demanding industrial environments. Its open seal type allows for easy re-lubrication and is suitable for high-speed operation up to 1,000 rpm.
51426 M Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 51426 | The basic bearing designation, indicating a thrust ball bearing with a 130mm bore and 270mm outside diameter. |
| M | Indicates the use of brass as the cage material. This provides high strength and is suitable for high-speed applications. |
51426 M Bearing Structural Features & Performance Benefits
The performance of the 51426 M is defined by its robust construction. The thrust-specific design features a housing washer and shaft washer, engineered to handle significant axial dynamic load ratings of 117,000 lbf and immense axial static load ratings of 389,250 lbf. The use of a stainless steel cage ensures dimensional stability and reduced wear at the limiting speed of 1,000 rpm. The open seal design, while not offering contact sealing, minimizes friction and is optimal for applications where re-lubrication is part of the maintenance schedule. Precision dimensional tolerances on the bore, outside diameter, and width guarantee a secure fit and reliable alignment in the assembly.
51426 M Bearing Typical Application Areas
This thrust ball bearing is commonly specified in heavy-duty machinery and systems where substantial axial forces are present. Key application areas include:
- Heavy-duty industrial gearboxes
- Vertical pumps and compressors
- Cranes and hoisting equipment
- Machine tool tables and indexing heads
- Marine propulsion systems
