6303-2Z/C3GJN Bearing Product Overview & Core Advantages
The 6303-2Z/C3GJN is a metric single row deep groove ball bearing designed for robust performance in demanding applications. Its key advantage lies in its ability to efficiently handle radial loads while offering a degree of axial load capacity in both directions. Featuring integral shielded seals, this bearing is pre-configured with a C3 radial internal clearance, making it exceptionally suitable for applications with thermal expansion or where interference fits are used. Its construction from high-grade chrome steel ensures durability and reliable operation, offering a compact and cost-effective solution for a wide range of industrial machinery.
Model Code Breakdown
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6303 | Basic Bearing Series & Size | Denotes a standard metric single row deep groove ball bearing with a 17mm bore, 47mm OD, and 14mm width. |
| 2Z | Shielded on Both Sides | Provides effective protection against contamination from solid particles while allowing for relatively high-speed operation compared to contact seals. |
| C3 | Radial Internal Clearance | Indicates a clearance greater than normal (CN), ideal for applications with high rigidity requirements, thermal gradients, or tight interference fits. |
| GJN | Grease Type | Specifies the type of high-performance, lithium-based grease pre-lubricated in the bearing, suitable for the specified temperature range. |
6303-2Z/C3GJN Bearing Structural Features & Performance Benefits
- Robust Construction & High Rigidity: Manufactured from through-hardened chrome steel for both rings and balls, this bearing provides excellent resistance to deformation under load, ensuring stable operation and contributing to high rigidity in the assembly.
- Optimized Load Capacity: The deep groove raceway and precision-ground components enable the bearing to carry significant radial dynamic loads (3057 lbf) and moderate axial loads, making it a versatile choice for combination loads.
- Enhanced Contamination Protection: The non-contact shielded (2Z) design effectively retains the factory-applied grease and excludes larger contaminants, extending bearing life and reducing maintenance needs.
- Ready-to-Install & Long-Lasting: Pre-lubricated with GJN grease and featuring a C3 clearance, the bearing is ready for immediate use in applications with operational heat buildup, ensuring consistent performance and longevity.
