Product Overview: The 51248 Thrust Ball Bearing
The 51248 Thrust Ball Bearing is a high-precision component specifically engineered to manage heavy axial (thrust) loads in a single direction. With key dimensions of 240mm Bore Diameter, 320mm Outer Diameter, and 60mm Thickness, this bearing is a robust solution for applications requiring high-load capacity and rotational precision along a shaft's axis. As part of our 51200 Series, it belongs to a family of single-direction Thrust Ball Bearings known for their reliability and performance. Its design consists of three separable parts: a shaft washer, a housing washer, and a ball and cage assembly, which simplifies mounting and inspection processes. This bearing is not suitable for radial loads; its sole purpose is to support forces parallel to the shaft.
Key Features of the 51248 Bearing
- Single-Direction Axial Load Support: Expertly designed to handle high thrust loads in one direction, ensuring stability for vertical and horizontal shafts.
- Separable Components: The shaft washer, housing washer, and ball cage assembly can be mounted separately, simplifying installation, maintenance, and inspection.
- High Precision and Rigidity: Manufactured to exacting standards to provide high running accuracy and stiffness, which is critical in precision machinery.
- Grooved Raceways: Both the shaft and housing washers feature grooved raceways to accommodate the steel balls, enabling smooth operation under heavy axial stress.
- Durable Steel Construction: Made from high-quality bearing steel for exceptional hardness, wear resistance, and a long operational lifespan.
- Optimized for Pure Thrust Loads: Its design is focused exclusively on managing axial forces, making it highly efficient for its intended applications.
Common Applications of 51248 Bearings
- Industrial Gearboxes: Provides support for vertical shafts and gears, managing the axial forces generated during operation.
- Machine Tool Spindles: Used in lathes, milling machines, and drill presses to ensure precise axial positioning and support under load.
- Crane Hooks and Swivels: Essential for supporting the heavy, rotating loads encountered in lifting and material handling equipment.
- Rotating Tables and Indexing Heads: Offers the rigidity and precision needed for accurate positioning in turntables and indexing machinery.
- Vertical Pumps and Motors: Supports the weight and thrust generated by vertical shaft assemblies in pumps and other rotating equipment.
- Extrusion Machinery: Manages the high axial pressures generated in plastic and metal extrusion processes.
- Antenna Rotators: Provides stable rotational support for large communication and radar antennas.
