Product Overview: The 51240 Thrust Ball Bearing
The 51240 is a high-performance single-direction Thrust Ball Bearing, engineered to manage high axial loads in one direction. With dimensions of 200x280x62mm, this bearing is a crucial component in heavy-duty machinery where precise axial support is required. As part of the 51200 Series, the 51240 features separable components—a shaft washer, a housing washer, and a ball and cage assembly—which simplifies mounting, dismounting, and inspection procedures. It is specifically designed to handle pure thrust loads and must not be subjected to any radial load. Its robust construction ensures reliability and longevity in demanding industrial applications.
Key Features of the 51240 Bearing
- Single-Direction Axial Load: Exclusively designed to support heavy axial (thrust) loads in a single direction.
- Separable Components: The design with separate washers and a ball-cage assembly allows for easy and convenient installation and maintenance.
- High-Grade Steel Construction: Manufactured from premium bearing steel for exceptional durability, hardness, and wear resistance under load.
- Precision Engineering: Ensures smooth operation and optimal load distribution across the rolling elements.
- Flat Seating: Both the shaft and housing washers have flat seating surfaces, simplifying the design of the surrounding components.
- High Axial Stiffness: Provides rigid support for shafts, minimizing axial displacement under load.
Common Applications
The 51240 bearing is essential in applications requiring high-capacity axial load support, such as:
- Industrial Gearboxes: Supports axial forces generated by helical and bevel gears.
- Machine Tool Spindles: Used in vertical milling machines, lathes, and drilling equipment to maintain spindle position.
- Crane Hooks and Hoists: Provides reliable rotational support for heavy lifting equipment.
- Vertical Pumps and Compressors: Manages the axial load from vertical shafts in industrial pumping systems.
- Extruders and Injection Molding Machines: Withstands the high thrust forces generated during material processing.
- Turntables and Indexing Tables: Ensures smooth and precise rotation in positioning equipment.
- Propeller Shafts: Applied in marine and aerospace applications to handle propeller thrust.
