E2.6311-2Z/C3 Bearing Product Overview & Core Advantages
The E2.6311-2Z/C3 is a single row deep groove ball bearing designed for superior performance in demanding industrial applications. Engineered with metric dimensions and manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing delivers reliable operation and long service life. Its key advantage lies in its ability to efficiently handle radial loads while offering robust construction for high rotational speeds. The combination of shielded design (2Z) and C3 radial internal clearance makes it particularly suitable for applications with thermal expansion or where precise shaft alignment is critical.
E2.6311-2Z/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| E2.6311 | Basic bearing designation with metric dimensions (55mm bore, 120mm OD) | Standardized sizing for easy integration |
| 2Z | Double shielded construction on both sides | Effective contamination protection without significant speed reduction |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion, ideal for high-temperature applications |
E2.6311-2Z/C3 Bearing Structural Features & Performance Benefits
Optimized Load Capacity: With a radial dynamic load rating of 16,658 lbf and static load rating of 10,116 lbf, this bearing provides exceptional durability under substantial radial forces. The single row deep groove design ensures optimal stress distribution across the raceways.
High-Speed Capability: Featuring a limiting speed of 6,300 rpm, the bearing maintains stable operation at elevated rotational speeds. The chrome steel cage and precision-ground components contribute to smooth, vibration-free performance.
Enhanced Protection System: The double shielded (2Z) construction effectively prevents contaminant ingress while maintaining low friction operation. This design extends bearing life in dusty or dirty environments without requiring complex sealing arrangements.
Thermal Stability: The C3 clearance provides additional internal space to accommodate thermal expansion during operation, preventing premature failure due to excessive preload in high-temperature applications (up to 120°C).
