Product Overview: The 51244 Thrust Ball Bearing
The 51244 is a single-direction thrust ball bearing, a critical component designed to manage purely axial loads in one direction. As a key part of our 51200 Series, which is a subcategory of our comprehensive Thrust Ball Bearings range, this bearing is engineered for high-precision applications. With an inner diameter of 220mm, an outer diameter of 300mm, and a height of 62mm, the 51244 is built to provide reliable axial support in heavy-duty machinery. Its design consists of separable components—a shaft washer, a housing washer, and a ball and cage assembly—which simplifies mounting and dismounting procedures.
This bearing is not suitable for radial loads. The shaft and housing washers have raceways for the balls, allowing for smooth, low-friction rotation under significant axial stress. It is an ideal choice for applications where precise axial positioning of a shaft is essential.
Key Features of the 51244 Bearing
- Axial Load Capacity: Specifically designed to accommodate heavy axial (thrust) loads in a single direction.
- Separable Design: The bearing's components (washers and ball cage assembly) can be mounted separately, facilitating easy installation and inspection.
- High Precision: Manufactured to tight tolerances to ensure high running accuracy in demanding applications.
- Low Friction: The design minimizes rotational friction, contributing to operational efficiency and reduced heat generation.
- Durable Construction: Made from high-quality, hardened bearing steel for excellent durability and a long service life.
- Grooved Raceways: Both the shaft and housing washers feature grooved raceways to effectively support and guide the balls.
Common Applications
- Industrial Gearboxes: Supports axial forces on vertical shafts and gears, ensuring stable operation.
- Rotating and Indexing Tables: Provides the necessary axial support for precision movement in machine tools and manufacturing equipment.
- Crane Hooks and Swivels: Manages the heavy axial loads encountered in lifting and material handling equipment.
