6307-2RS1N/C3 HT51 Bearing Product Overview & Core Advantages
The 6307-2RS1N/C3 HT51 is a metric single row deep groove ball bearing engineered for robust performance in demanding applications. This sealed bearing excels at handling radial loads while offering operational reliability. Its key advantages include a C3 radial internal clearance for thermal expansion management in applications with elevated operating temperatures, and an outer ring snap ring groove for simplified axial location and secure mounting within a housing. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides consistent, high-quality performance.
6307-2RS1N/C3 HT51 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Benefit |
|---|---|---|
| 2RS1 | Contact seals on both sides | Provides superior protection against contaminant ingress and grease leakage compared to non-contact shields. |
| N | Snap ring groove in the outer ring | Facilitates axial positioning, simplifies housing design, and reduces assembly costs. |
| C3 | Greater than normal radial internal clearance | Accommodates shaft and housing fits, and thermal expansion, preventing preload and potential seizure. |
| HT51 | High-temperature grease filling | Enables reliable operation within the specified temperature range of -30°C to 120°C. |
6307-2RS1N/C3 HT51 Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: The single row deep groove raceway and high-quality chrome steel construction (rings, balls, and cage) provide a robust design capable of handling significant radial dynamic load ratings of 7509 lbf and static ratings of 4339 lbf.
- Effective Sealing for Long Service Life: The integral contact seals (2RS1) effectively shield the bearing interior from contaminants like dust and moisture, while retaining the factory-applied HT51 lubricant. This combination creates a maintenance-free solution for the life of the bearing in many applications.
- Optimized for Thermal Stability: The C3 clearance is a critical feature that prevents excessive preload and potential bearing failure in applications where operational heat causes differential expansion between the shaft, bearing, and housing.
- Simplified Mounting and Positioning: The snap ring groove (N) on the outer ring allows for secure axial location within a housing, simplifying assembly and reducing the need for complex housing shoulders or lock nuts.
6307-2RS1N/C3 HT51 Bearing Typical Application Areas
