Product Overview: The 5131/M (51311) Single Direction Thrust Ball Bearing
The 5131/M (industry standard designation 51311/M) is a high-performance single direction Thrust Ball Bearing designed to manage purely axial loads in one direction. Part of the robust 51300 Series, this bearing features standard dimensions of 55x100x32mm. It is composed of a shaft washer, a housing washer, and a ball and cage assembly, which are separable for simplified mounting and maintenance. The '/M' suffix indicates a machined brass cage, making this bearing exceptionally suitable for applications requiring higher speeds, greater rigidity, and superior performance under demanding conditions.
Engineered for precision, the 5131/M (51311) ensures reliable support for vertical shafts and rotating components. It is not designed to accommodate any radial load. As a specialist supplier of industrial components, we provide high-quality bearings that meet rigorous industry standards, ensuring longevity and operational excellence in your machinery.
Key Features of the 5131/M (51311) Bearing
- Axial Load Capacity: Specifically designed to support high axial (thrust) loads in a single direction.
- Separable Design: The components (washers and ball cage assembly) can be mounted separately, simplifying installation and inspection.
- Machined Brass Cage: The '/M' designation signifies a strong, low-friction brass cage that allows for higher rotational speeds and operating temperatures.
- High Precision: Manufactured to precise tolerances to ensure smooth, low-friction operation and accurate shaft location.
- Durable Construction: Made from high-quality, through-hardened bearing steel for extended service life and reliability.
- Interchangeability: Adheres to standard dimensions for easy replacement and integration into existing systems.
Common Applications
- Vertical Pumps and Motors: Provides robust axial support for vertical shafts against gravitational and operational forces.
- Machine Tool Spindles: Used in drilling machines, lathes, and milling machines to handle axial cutting forces.
- Rotating and Indexing Tables: Ensures smooth and precise rotation in manufacturing and assembly equipment.
- Industrial Gearboxes: Manages axial forces generated by helical and bevel gears.
- Lifting Equipment: Essential in crane hooks, jacks, and other heavy lifting mechanisms to support the load.
- Centrifuges and Separators: Supports the rotating assembly and handles the significant axial forces generated during operation.
