Product Overview: The 51228 Thrust Ball Bearing
The 51228 bearing is a high-capacity, single-direction thrust ball bearing engineered to manage heavy axial loads in one direction. With a bore diameter of 140mm, an outer diameter of 210mm, and a thickness of 53mm, this bearing is a robust component in our 51200 Series. As part of the wider Thrust Ball Bearings category, it is designed with separable components—a shaft washer, a housing washer, and a ball and cage assembly—which simplifies mounting and maintenance procedures. The grooved raceways in the washers are precisely engineered to accommodate the steel balls, ensuring smooth and efficient transmission of axial forces.
This bearing type is not suitable for radial loads. Its primary function is to support a rotating shaft against a fixed housing, making it indispensable in applications with significant vertical or horizontal thrust. As a premier supplier of industrial mechanical parts, we ensure our 51228 bearings meet stringent quality standards for reliable performance in demanding industrial environments.
Key Features of the 51228 Bearing
- Separable Components: The shaft washer, housing washer, and ball assembly can be mounted independently, simplifying installation and inspection.
- High Axial Load Capacity: Specifically designed to handle substantial thrust loads in a single direction.
- Precision Engineered: Manufactured to precise dimensions for consistent performance and interchangeability.
- Low Friction Operation: The ball and cage assembly is designed to minimize rotational friction and heat generation.
- Durable Construction: Made from high-quality bearing steel for excellent durability and resistance to wear and deformation under load.
- Grooved Raceways: Ensures optimal contact between balls and washers for efficient load distribution.
