6307-2RS1/C4 Bearing Product Overview & Core Advantages
The 6307-2RS1/C4 is a single row deep groove ball bearing designed for reliable performance in demanding applications. This sealed bearing excels at handling radial loads while also accommodating moderate axial loads in both directions. Its key advantages include a generous C4 radial internal clearance for stable operation under thermal expansion, and integrated contact seals (2RS1) that provide excellent protection against contamination. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers a robust balance of precision, durability, and value for a wide range of industrial machinery.
6307-2RS1/C4 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 6307 | Basic bearing designation indicating a Metric series, 35mm bore, 80mm OD, and 21mm width. |
| 2RS1 | Features contact seals on both sides. The "RS1" suffix denotes nitrile rubber seals, providing superior protection against dust and moisture ingress compared to non-contact shields. |
| /C4 | Specifies a greater than normal radial internal clearance. This is critical for applications with significant thermal gradients or where fits result in a reduction of operating clearance. |
6307-2RS1/C4 Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured from chrome steel for rings, balls, and cage, this bearing delivers high strength and wear resistance. With a dynamic load rating of 7509 lbf and a static load rating of 4339 lbf, it is engineered for long service life under substantial radial loads.
- Enhanced Sealing for Contaminated Environments: The 2RS1 double seals effectively retain lubricant and exclude contaminants, making this bearing suitable for applications where dirt, dust, or moisture is present, thereby enhancing reliability.
- Optimized for Thermal Stability: The C4 radial internal clearance is a key feature that prevents pre-loading and potential seizure in applications where operational heat causes the inner ring to expand more than the outer ring.
- Ready-to-Install Convenience: The bearing comes pre-greased and sealed, making it a maintenance-free component that is ready for immediate installation, reducing assembly time and cost.
6307-2RS1/C4 Bearing Typical Application Areas
The 6307-2RS1/C4 is a versatile component found in numerous industrial sectors, including:
- Electric Motors & Generators: Ideal for supporting shafts in standard industrial motors.
- Material Handling Equipment: Used in conveyor pulleys, rollers, and gearboxes.
- Agricultural Machinery: Suitable for tractors, combines, and other equipment operating in harsh, dusty conditions.
- Industrial Fans & Blowers: Provides reliable support for fan shafts.
- General Industrial Machinery: A common choice for pumps, compressors, and other machinery requiring a robust, sealed ball bearing.
