6309-2ZNRJEM Bearing Product Overview & Core Advantages
The 6309-2ZNRJEM is a single row deep groove ball bearing engineered for exceptional performance in demanding applications. Its core advantage lies in its ability to efficiently handle radial loads while its snap ring groove on the outer ring provides secure axial location within a housing, simplifying assembly and enhancing system rigidity. Manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing offers reliable precision and is pre-shielded for contamination protection, making it a robust and cost-effective solution for a wide range of industrial machinery.
6309-2ZNRJEM Bearing Model Code Explained, Specifications & Naming Convention
The model number 6309-2ZNRJEM is decoded as follows:
- 6309: Standard designation for a medium-duty, single row deep groove ball bearing with a 45mm bore, 100mm OD, and 25mm width.
- 2Z: Signifies that the bearing is equipped with non-contact shields on both sides. These shields protect the internal components from large particulate contaminants while allowing for high-speed operation with minimal friction.
- NR: Indicates that the outer ring features a snap ring groove. This groove accommodates a snap ring, which axially locates the bearing in the housing, eliminating the need for complex housing shoulders and reducing assembly costs.
- JEM: This suffix combination typically refers to a specific internal design and radial internal clearance group. In this case, it corresponds to the CN clearance, which is the standard normal clearance for general applications.
6309-2ZNRJEM Bearing Structural Features & Performance Benefits
- Robust Load Capacity: The deep groove raceway and high-quality chrome steel construction (rings, balls, and cage) provide a high dynamic load rating of 11,915 lbf and a static load rating of 7,194 lbf, ensuring durability under significant radial stresses.
- Simplified Axial Location: The integrated snap ring groove (NR) on the outer ring is a key structural feature. It allows for secure axial positioning within the housing, which increases system stability and simplifies the design and machining of the surrounding components.
- Contamination Protection & Speed: The non-contact shields (2Z) effectively protect the bearing interior from dust and debris without generating significant heat from contact friction, supporting a limiting speed of 6,700 rpm.
- Standard Precision & Clearance: Built to ABEC 1 (ISO P0) tolerance class with CN normal radial internal clearance, this bearing delivers consistent and reliable performance for the vast majority of industrial applications.
6309-2ZNRJEM Bearing Typical Application Areas
The 6309-2ZNRJEM is ideally suited for applications requiring reliable radial load support and easy axial location. Common uses include:
- Electric Motors and Generators
- Gearboxes and Power Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Conveyors
- Agricultural Machinery
