6305-2ZJEM Bearing Product Overview & Core Advantages
The 6305-2Z JEM is a single row deep groove ball bearing designed for exceptional reliability in demanding applications. This metric bearing features shielded construction on both sides, offering robust protection against contaminant ingress. Engineered with chrome steel rings, balls, and cage, it delivers high durability and consistent performance. Its key advantages include a high radial dynamic load rating of 4631 lbf, suitability for high-speed operation up to 11,000 rpm, and compliance with ABEC 1 | ISO P0 tolerance standards, making it an ideal choice for applications requiring precision and long service life.
6305-2ZJEM Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Benefit |
|---|---|---|
| -2Z | Non-contact steel shields on both sides | Provides effective contamination protection while maintaining low friction and high-speed capability. |
| JEM | Manufacturer-specific designation for internal specifications (e.g., cage design, internal clearance CN) | Ensures optimized performance for a specific range of operating conditions and load capacities. |
6305-2ZJEM Bearing Structural Features & Performance Benefits
- Shielded Design & Contamination Resistance: The 2Z shields protect the bearing internals from dust and debris, significantly extending service life in unclean environments without the torque increase associated with contact seals.
- High-Speed Capability: The combination of a chrome steel cage, precision-ground chrome steel balls, and CN radial internal clearance allows for stable operation at limiting speeds up to 11,000 rpm.
- Robust Load Capacity: The single row deep groove raceway geometry is optimized to support high radial loads (4631 lbf dynamic) and moderate axial loads in both directions.
- Precision & Consistency: Manufactured to ABEC 1 | ISO P0 tolerance class, this bearing ensures smooth running and precise shaft positioning, contributing to overall system accuracy.
6305-2ZJEM Bearing Typical Application Areas
This versatile bearing is commonly specified in:
- Electric Motors and Gearboxes
- Industrial Pumps and Compressors
- Material Handling Equipment (conveyors, fans)
- Agricultural and Automotive Auxiliary Machinery
- General Industrial Machinery requiring reliable radial load support
