6309-ZNRJEM Bearing Product Overview & Core Advantages
The 6309-ZNRJEM is a single row deep groove ball bearing engineered for robust performance in demanding applications. This metric bearing is characterized by its ability to accommodate high radial loads and moderate axial loads in both directions. A key distinguishing feature is the snap ring fitted on its outer ring, which provides secure axial location within a housing, simplifying assembly and enhancing operational reliability. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers dependable precision and is an excellent choice for applications requiring a compact, high-capacity, and easily mounted bearing solution.
6309-ZNRJEM Bearing Model Code Explained, Specifications & Naming Convention
The model number 6309-ZNRJEM is decoded as follows:
- 6309: Basic series designation indicating a medium-duty, single row deep groove ball bearing with a 45mm bore, 100mm OD, and 25mm width.
- Z: Signifies a shielded seal on one side, protecting the bearing interior from large contaminants.
- NR: Indicates a snap ring groove on the outer ring.
- JEM: Specifies that a snap ring is supplied fitted to the bearing, ensuring immediate readiness for installation.
6309-ZNRJEM Bearing Structural Features & Performance Benefits
- High Load Capacity & Rigidity: The deep groove raceway and robust chrome steel construction (rings, balls, and cage) provide high radial dynamic load rating of 11915 lbf and static load rating of 7194 lbf, ensuring stable operation under significant loads.
- Simplified Housing Design & Secure Location: The integrated snap ring eliminates the need for complex housing shoulders or end caps, reducing component count and assembly time while providing reliable axial positioning.
- Contamination Protection: The shielded design (Z) offers effective protection against large particulate contaminants, extending bearing service life.
- Broad Operating Range: With a temperature range of -30°C to 120°C, this bearing is suitable for various industrial environments.
