Product Overview: The 51408 Thrust Ball Bearing
The 51408 Thrust Ball Bearing is a high-performance component engineered to manage purely axial loads in a single direction. As a key part of our 51400 Series, this bearing is a specialized solution within our broader Thrust Ball Bearings collection. Its design consists of three separable parts: a shaft washer, a housing washer, and a ball and cage assembly, which simplifies mounting and dismounting procedures. With a bore diameter of 40mm, an outer diameter of 90mm, and a thickness of 33mm, the 51408 is built for applications where precision axial support is critical. It is not suitable for radial loads, but excels in providing smooth, low-friction performance under high thrust conditions.
Key Features of the 51408 Bearing
- Separable Components: The shaft washer, housing washer, and ball-cage assembly can be mounted independently, simplifying installation and maintenance.
- Axial Load Capacity: Specifically designed to accommodate heavy axial loads in one direction, ensuring stability for vertical shafts and rotating assemblies.
- High Precision: Manufactured to tight tolerances to provide high running accuracy, essential for applications like machine tool spindles.
- Durable Construction: Made from high-quality, through-hardened bearing steel for excellent durability and extended service life.
- Simple Mounting Surface: Features a flat seat on the housing washer, allowing for a straightforward and cost-effective housing design.
- Low Friction Operation: The ball and cage design ensures smooth rotation, minimizing friction and operational heat under axial stress.
Common Applications
- Machine Tool Spindles: Provides the necessary axial rigidity and precision for lathes, milling machines, and grinders.
- Vertical Pumps and Motors: Supports the axial weight and operational thrust of vertical shaft arrangements.
- Rotating and Indexing Tables: Ensures smooth and accurate rotation in manufacturing and assembly equipment.
- Lifting Equipment: Commonly used in crane hooks, jacks, and other lifting mechanisms to handle heavy axial forces.
- Automotive Applications: Found in clutch release systems and other mechanisms requiring management of thrust loads.
- Industrial Gearboxes: Supports axial forces generated by helical and bevel gears, preventing shaft movement and ensuring proper gear mesh.
Benefits of Using the 51408 Bearing
- Reliable Axial Support: Effectively manages high thrust loads, enhancing the stability and reliability of the machinery.
- Simplified Assembly: The separable design allows for easier and quicker installation, reducing downtime and labor costs.
- Extended Equipment Life: By properly supporting axial forces, it reduces stress on other components, leading to a longer operational life for the entire assembly.
- Cost-Effective Solution: Offers an economical way to handle single-direction axial loads compared to more complex bearing arrangements.
- Improved Performance: Low-friction characteristics contribute to higher operational efficiency and reduced energy consumption.
- Interchangeability: Manufactured to industry-standard dimensions, making it an easy replacement for existing bearings.
