Product Overview: The 51248M Thrust Ball Bearing
The 51248M is a high-capacity, single-direction thrust ball bearing engineered to manage significant axial loads in one direction. With dimensions of 240mm bore diameter, 360mm outer diameter, and 95mm thickness, this bearing is a robust solution for heavy-duty applications. As part of our 51200 Series, it is a key component in our wider range of Thrust Ball Bearings. The 'M' suffix signifies a machined brass cage, which provides superior strength and durability, making it suitable for higher speeds and demanding operating conditions compared to standard steel cages.
This bearing's design consists of three separable parts: a shaft washer, a housing washer, and the ball and cage assembly. This feature simplifies mounting and dismounting procedures, allowing for individual installation of the components. The 51248M is specifically designed to handle thrust loads and must not be subjected to any radial load. It is an essential component for ensuring smooth and reliable operation in machinery with vertical shafts and other axial load applications.
Key Features of the 51248M Bearing
- Single-Direction Axial Load Capacity: Specifically designed to accommodate heavy thrust loads in a single direction.
- Separable Components: The shaft washer, housing washer, and ball cage assembly can be mounted separately, simplifying installation and maintenance.
- Machined Brass Cage: Offers excellent strength, stability, and guidance for the balls, suitable for high-speed and high-temperature applications.
- High Precision Manufacturing: Produced to exacting standards to ensure dimensional accuracy and reliable performance under load.
- Durable Construction: Made from high-quality, through-hardened bearing steel for extended service life and wear resistance.
- Optimized Raceway Design: Grooved raceways in the washers are designed for optimal load distribution and low-friction operation.
Common Applications
- Vertical Shafts: Ideal for supporting vertical rotating shafts in pumps, motors, and generators.
- Industrial Gearboxes: Used to manage axial forces generated by helical and bevel gears.
- Crane Hooks and Swivels: Provides reliable support for heavy lifting and rotating equipment.
- Machine Tool Spindles: Ensures precision and rigidity in drilling, milling, and grinding machines.
- Rotating Tables and Turntables: Facilitates smooth rotation in indexing tables and large industrial turntables.
- Screw Jacks and Actuators: Manages the high axial forces in linear motion systems.
- Extrusion Machinery: Supports the extruder screw, handling the immense thrust generated during the process.
Benefits of Using the 51248M Bearing
- Enhanced Axial Rigidity: Provides strong, stable support for shafts, minimizing axial movement and improving machine accuracy.
- Simplified Assembly: The separable design allows for easier and more efficient mounting and dismounting, reducing downtime.
- High Reliability: The robust construction and machined brass cage contribute to a long and predictable service life, even in tough environments.
- Improved Operational Efficiency: Low-friction characteristics help reduce energy consumption and heat generation.
- Cost-Effective Maintenance: The ability to replace individual components can be more economical than replacing an entire non-separable bearing unit.
- Versatile Heavy-Duty Performance: Suitable for a wide range of industrial applications requiring high thrust load management.
