6302-ZJEM Bearing Product Overview & Core Advantages
The 6302-ZJEM is a single row deep groove ball bearing designed for exceptional performance in demanding applications. Engineered with precision ABEC 1 tolerances and constructed entirely from high-grade chrome steel, this bearing delivers reliable operation and long service life. Its core advantage lies in its ability to efficiently handle radial loads while offering a high limiting speed of 17,000 rpm. The inclusion of shielded seals (Z) provides effective contamination protection, making it a robust and durable choice for a wide range of industrial machinery.
6302-ZJEM Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Code | Technical Meaning |
|---|---|---|
| Basic Designation | 6302 | Standard single row deep groove ball bearing with 15mm bore, 42mm OD, 13mm width. |
| Seal Type | Z | One side shielded. Protects against contaminants while minimizing friction. |
| Internal Design | EM | Optimized internal geometry and chrome steel cage for enhanced performance and stability. |
6302-ZJEM Bearing Structural Features & Performance Benefits
- Robust Construction: Manufactured from chrome steel for both rings, balls, and cage, ensuring high strength, wear resistance, and dimensional stability under load.
- Optimized Load Capacity: The deep groove raceway and ABEC 1 precision enable efficient handling of the radial dynamic load rating of 2563 lbf and static load rating of 1225 lbf.
- High-Speed Capability: The low-friction design, combined with the CN radial internal clearance and stable cage, supports a high limiting speed of 17,000 rpm.
- Contamination Resistance: The shielded (Z) design effectively excludes larger particulate contaminants, extending bearing life in unclean environments. The bearing is supplied without lubrication, allowing for application-specific greasing.
- Wide Temperature Range: Suitable for operating temperatures from -30°C to 120°C, accommodating various industrial conditions.
