6302-2Z/C3GJN Bearing Product Overview & Core Advantages
The 6302-2Z/C3 is a single row deep groove ball bearing designed for reliable performance in a wide range of industrial applications. Its key advantages include the ability to accommodate significant radial loads and moderate axial loads in both directions. The inclusion of shields (2Z) provides effective protection against contamination, while the C3 radial internal clearance makes it suitable for applications involving thermal expansion or where interference fits are used. This bearing offers a compact design, high operational reliability, and is supplied without lubrication for use in systems with centralized lubrication or where a specific lubricant is required.
Model Code Breakdown
| Code Segment | Meaning | Technical Implication |
|---|---|---|
| 6302 | Basic Bearing Number | Indicates a single row deep groove ball bearing with a 15mm bore, 42mm OD, and 13mm width. |
| 2Z | Shielded on Both Sides | Provides effective protection against contamination while allowing for high-speed operation. The bearing is not contact-sealed, minimizing friction. |
| C3 | Radial Internal Clearance | Specifies a clearance greater than normal (C0), making it ideal for applications with expected thermal expansion or interference fits. |
6302-2Z/C3GJN Bearing Structural Features & Performance Benefits
- Robust Construction: Manufactured from chrome steel for both rings, balls, and cage, ensuring high strength, durability, and resistance to wear.
- High Load Capacity: Engineered to handle substantial radial dynamic loads (2563 lbf) and radial static loads (1225 lbf), providing reliable performance under demanding conditions.
- Optimized for Versatility: The C3 internal clearance accommodates shaft and housing fits that may cause a reduction in internal clearance, as well as differential thermal expansion during operation.
- Contamination Protection: The non-contact shields (2Z) effectively protect the bearing interior from large particulate contaminants, extending service life without significantly increasing friction or limiting the limiting speed (17,000 rpm).
- Broad Temperature Range: Suitable for operating temperatures from -30°C to 120°C, making it adaptable to various environmental conditions.
