51330 M Bearing Product Overview & Core Advantages
The 51330 M is a high-capacity metric thrust ball bearing engineered for demanding applications requiring exceptional axial load handling. Designed exclusively for thrust loads, this bearing features a robust construction using 52100 Chrome Steel for both rings and balls, ensuring high strength and durability. Its precision ground raceways and strict dimensional tolerances guarantee reliable performance in high-load, moderate-speed environments, making it an ideal component for heavy-duty industrial machinery.
51330 M Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning | Significance |
|---|---|---|
| M | Brass Cage | Indicates the use of a brass (copper alloy) cage, offering excellent strength and guidance for the balls, suitable for high-load and high-vibration applications. |
| (No Seal Suffix) | Open (Unsealed) | The bearing is supplied without integral seals, allowing for custom lubrication schemes and optimal heat dissipation in controlled environments. |
51330 M Bearing Structural Features & Performance Benefits
- Exceptional Thrust Load Capacity: Engineered with a large contact angle and high-grade components to handle substantial axial dynamic load ratings of 95175 lbf and axial static load ratings of 328500 lbf, providing reliable support in heavy thrust applications.
