6312-Z/C3GJN Bearing Product Overview & Core Advantages
The 6312-Z/C3GJN is a single row deep groove ball bearing engineered for reliable performance in demanding industrial applications. This metric bearing features shielded construction on one side, providing effective protection against contaminant ingress while maintaining high operational efficiency. Its C3 radial internal clearance makes it particularly suitable for applications with thermal expansion considerations or where interference fits are used. Manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing delivers consistent performance and high reliability across diverse operating conditions.
Model Code Detailed Breakdown
| Suffix Code | Technical Meaning | Performance Benefit |
|---|---|---|
| -Z | One-side shielded | Protects against contaminants while allowing easy relubrication from the open side |
| /C3 | Greater than normal radial internal clearance | Accommodates thermal expansion and interference fits, reducing operational stress |
| GJN | Lubrication: None (grease-free) | Enables custom lubrication selection for specific application requirements |
6312-Z/C3GJN Bearing Structural Features & Performance Benefits
Optimized Load Capacity: With a radial dynamic load rating of 18,412 lbf and radial static load rating of 11,735 lbf, this bearing provides excellent performance under substantial radial loads. The deep groove raceway design enables it to handle moderate axial loads in both directions.
High-Speed Capability: Featuring a limiting speed of 5,300 rpm, the bearing is suitable for high-speed applications. The precision-ground chrome steel components and optimized cage design contribute to smooth operation at elevated rotational speeds.
Robust Construction: Manufactured entirely from chrome steel for rings, balls, and cage, this bearing offers superior strength and durability. The material composition ensures excellent wear resistance and long service life under demanding conditions.
Temperature Resilience: Operating effectively within a temperature range of -30°C to 120°C, this bearing maintains performance across diverse environmental conditions and industrial applications.
