6307-2RS1/C3 Bearing Product Overview & Core Advantages
The 6307-2RS1/C3 is a metric single row deep groove ball bearing engineered for robust performance in demanding applications. Its primary advantage lies in its ability to efficiently handle radial loads while also accommodating moderate axial loads in both directions. The bearing features integrated contact seals (2RS1) for superior contamination protection and is supplied with a C3 radial internal clearance, making it exceptionally suitable for applications involving thermal expansion or where interference fits are used. This combination of reliable sealing, optimized clearance, and high load capacity makes it a versatile and durable choice for a wide range of industrial machinery.
6307-2RS1/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6307 | Basic bearing series, defining the boundary dimensions: 35mm bore, 80mm OD, 21mm width. | Standardized size for easy interchangeability and sourcing. |
| 2RS1 | Bearing is fitted with two NBR contact seals on both sides. | Provides excellent protection against contaminants and retains lubricant, enhancing service life and enabling maintenance-free operation in many environments. |
| C3 | Specifies a radial internal clearance greater than the Normal (CN) group. | Accommodates thermal expansion from high operating speeds or tight interference fits, preventing premature failure due to excessive preload. |
6307-2RS1/C3 Bearing Structural Features & Performance Benefits
- Deep Groove Raceway & High-Capacity Design: The uninterrupted deep groove raceways on both rings enable smooth operation under high radial loads and accommodate combined (radial and axial) loads.
- Integrated Sealing Solution: The 2RS1 contact seals are molded from Nitrile Rubber (NBR) and are lightly sprung against the inner ring land, forming an effective barrier against dust, dirt, and moisture. This design significantly extends the bearing's operational lifespan in harsh conditions.
- Optimized Internal Clearance: The C3 clearance is a critical feature for applications prone to thermal expansion, such as in electric motors or gearboxes. It ensures optimal performance by preventing internal preload that can lead to overheating and increased friction.
- Robust Material Construction: Manufactured from chrome steel for rings, balls, and cage, the bearing offers high strength, wear resistance, and long-term dimensional stability.
- High-Speed Capability: With a limiting speed of 8,500 rpm, it is well-suited for a variety of high-speed applications, supported by its precision-ground components and balanced design.
6307-2RS1/C3 Bearing Typical Application Areas
The 6307-2RS1/C3 is a workhorse component found in numerous industrial sectors due to its reliability and versatility. Key application areas include:
- Electric Motors and Generators: A common choice for motor shafts, benefiting from the C3 clearance for thermal management and seals for contamination protection.
- Industrial Gearboxes and Transmissions: Used to support shafts under significant radial loads.
- Material Handling Equipment: Ideal for conveyor pulleys, rollers, and fans.
- Agricultural Machinery: Employed in pumps, gearboxes, and other components exposed to dusty environments.
- General Industrial Machinery: A reliable option for pumps, compressors, and blowers where sealed, maintenance-free operation is desired.
