6302-2RSJEM Bearing Product Overview & Core Advantages
The 6302-2RS JEM is a single row deep groove ball bearing designed for reliable performance in a wide range of industrial applications. Its key advantage lies in its sealed construction (2RS), which provides effective protection against contaminants and retains lubricant, making it suitable for environments where maintenance access is difficult. This bearing is engineered to handle primarily radial loads and is manufactured to ABEC 1 (ISO P0) precision standards, offering a robust and cost-effective solution for general machinery. Its compact design and high-quality chrome steel construction ensure durability and consistent operation.
6302-2RSJEM Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 6302 | Basic bearing designation indicating a metric single row deep groove ball bearing with a 15mm bore, 42mm OD, and 13mm width. |
| 2RS | Sealing type: Contact seals on both sides. This provides superior protection against dust, moisture, and other contaminants compared to shielded or open bearings. |
| JEM | Manufacturer-specific suffix. This often indicates a specific internal specification, standard radial internal clearance (CN), and the use of chrome steel for all core components. |
6302-2RSJEM Bearing Structural Features & Performance Benefits
- Sealed for Longevity: The double-sided contact seals (2RS) effectively prevent the ingress of contaminants and the egress of lubricant, significantly extending bearing service life and enabling operation in harsh conditions. This creates a maintenance-free solution for the initial operational period.
- Robust Load Capacity: The deep groove raceway and high-quality chrome steel construction enable the bearing to carry significant radial dynamic loads (2563 lbf) and radial static loads (1225 lbf).
- Optimized for General Performance: Manufactured to ABEC 1 precision with standard (CN) radial internal clearance, this bearing offers a reliable balance of running accuracy, speed capability (up to 17,000 rpm), and operational smoothness for most industrial applications.
- Durable Material Construction: The rings, balls, and cage are all made from chrome steel, providing high hardness, wear resistance, and a long operational lifespan under typical loads and speeds.
6302-2RSJEM Bearing Typical Application Areas
