I. Product Overview
The 51202 bearing is a specialized member of the thrust ball bearing family, engineered to meet the demands of applications with significant axial loads. Its unique design allows for efficient handling of forces parallel to the axis of rotation, making it a crucial component in diverse mechanical systems. Employing advanced manufacturing techniques and stringent quality control, the 51202 bearing offers reliable performance and a long - lasting service life, catering to a wide range of industrial and commercial applications.
II. Core Technical Parameters
Parameter | Details |
Bore Diameter | 15 mm. This dimension is precisely machined to ensure a snug and secure fit on the shaft. The tight manufacturing tolerances prevent any slippage or misalignment during operation, which is essential for effective axial load transfer and smooth rotational motion. A proper fit guarantees that the bearing can efficiently handle the forces exerted on it without compromising performance. |
Outer Diameter | 32 mm. The outer diameter of the 51202 bearing is carefully calibrated to interface seamlessly with the bearing housing. This size is optimized to evenly distribute axial loads, enhancing the bearing's stability and overall performance within the mechanical system. A well - sized outer diameter helps in dissipating the applied forces, thereby extending the bearing's lifespan. |
Height | 12 mm. The height of the 51202 bearing is designed to balance structural strength and load - bearing capacity. Despite its relatively compact height, it can withstand substantial axial loads due to its specialized internal design. The height also plays a role in determining the bearing's compatibility with other components in the mechanical setup. |
Bearing Type | As a thrust ball bearing, the 51202 is specifically designed to support axial loads. It consists of a set of balls positioned between two raceways, with one raceway typically attached to the shaft and the other to the housing. This configuration enables the bearing to efficiently transfer axial forces while minimizing friction through the rolling motion of the balls. |
Cage Material | Common cage materials for the 51202 bearing include steel and nylon. Steel cages offer high strength and durability, making them suitable for applications involving heavy loads and high - speed operation. They effectively guide the balls, ensuring their even distribution and smooth movement. Nylon cages, on the other hand, are lightweight and help reduce friction and noise, making them ideal for applications where quiet operation is a priority. |
Precision Grade | The 51202 bearing is available in various precision grades, including standard grades that meet industry - recognized standards for dimensional accuracy, roundness, and surface finish. Higher - precision grades with tighter tolerances are also available for applications requiring extremely accurate and smooth operation, such as precision machinery. |
Axial Dynamic Load Rating | The 51202 bearing is engineered to handle a significant axial dynamic load. The exact value depends on factors such as design, material quality, and manufacturing processes. This high load - bearing capacity makes it suitable for applications with continuous or intermittent axial forces, such as in certain pumps and machine tools. |
Axial Static Load Rating | The axial static load rating represents the maximum static axial load the bearing can support without permanent deformation. This is crucial for applications where the bearing may be subjected to static or slowly varying loads, such as during equipment standby or start - stop cycles. |
Friction Coefficient | The 51202 bearing is designed with a low friction coefficient. The smooth surface finish of the balls and raceways, combined with appropriate lubrication, minimizes friction during operation. Reduced friction improves energy efficiency, reduces wear, and lowers heat generation, extending the bearing's service life. |
Lubrication Requirements | Proper lubrication is essential for the 51202 bearing. Grease lubrication is commonly used for general - purpose applications, providing long - lasting protection and reducing contamination. In high - speed or extreme temperature environments, oil lubrication may be preferred for better cooling and performance. Some bearings come pre - lubricated for easier installation. |
Sealing Options | To protect against dust, dirt, and moisture, the 51202 bearing offers various sealing options. Rubber seals provide good protection against contaminants, fitting tightly around the bearing to prevent ingress. Metal shields offer more robust protection against larger debris. Sealed bearings are particularly useful in harsh or dirty operating environments. |
