6312-2Z/GJN Bearing Product Overview & Core Advantages
The 6312-2Z is a single row deep groove ball bearing featuring integral shielded protection. Engineered for radial load applications, this metric bearing delivers reliable performance in a compact design. Its ABEC 1 | ISO P0 tolerance class ensures consistent operation, while the CN radial internal clearance provides optimal performance under standard operating conditions. The bearing comes unlubricated, offering flexibility for specialized lubrication requirements.
Model Code Breakdown
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| 63 | Medium duty series | Balanced load capacity and dimensional proportions |
| 12 | Bore diameter: 60 mm | Standard shaft size compatibility |
| 2Z | Double shielded both sides | Contaminant protection while maintaining high-speed capability |
6312-2Z/GJN Bearing Structural Features & Performance Benefits
Optimized Load Distribution: The single row deep groove raceway geometry enables efficient handling of radial loads with a dynamic load rating of 18,412 lbf and static load rating of 11,735 lbf.
Shielded Protection: Both sides feature steel shields (2Z) that provide effective contaminant exclusion while allowing higher limiting speeds (5,300 rpm) compared to contact seals.
Precision Manufacturing: Manufactured to ABEC 1 | ISO P0 tolerance standards with chrome steel construction throughout (rings, balls, and cage), ensuring dimensional stability and consistent performance.
Thermal Compatibility: Operating temperature range of -30°C to 120°C accommodates most industrial environments without performance degradation.
