6306-2Z/C4GJN Bearing Product Overview & Core Advantages
The 6306-2Z/C4GJN is a single row deep groove ball bearing designed for high-performance applications requiring reliable operation under radial loads. This shielded bearing features a C4 radial internal clearance for applications with thermal expansion considerations. Manufactured to ABEC 1 | ISO P0 tolerance standards with precision-ground chrome steel components, it delivers consistent performance and long service life. Its pre-lubricated design with GJN grease ensures immediate operation and reduced maintenance requirements.
6306-2Z/C4GJN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| 6306 | Standard deep groove ball bearing series with 30mm bore | Proven design for radial load applications |
| 2Z | Double-sided steel shields | Effective contamination protection, extended service life |
| C4 | Greater than normal radial internal clearance | Accommodates thermal expansion in high-temperature applications |
| GJN | Polyurea thickened grease, temperature range -30°C to +150°C | Enhanced high-temperature performance and lubrication stability |
6306-2Z/C4GJN Bearing Structural Features & Performance Benefits
Optimized Load Distribution: The deep groove raceway geometry enables efficient handling of radial loads while accommodating moderate axial loads in both directions, making it suitable for various mounting configurations.
Enhanced Contamination Resistance: The double-sided steel shields (2Z) provide effective protection against particulate contamination while minimizing friction compared to contact seals, contributing to higher limiting speeds up to 9,600 rpm.
Thermal Compensation Design: The C4 radial clearance accommodates differential thermal expansion between shaft and housing, preventing preload conditions in applications with significant temperature variations.
Precision Manufacturing: Manufactured from high-grade chrome steel with ABEC 1 | ISO P0 precision, ensuring consistent dimensional accuracy and smooth operation throughout the specified temperature range of -30°C to 120°C.
