6307-RS1/C3 Bearing Product Overview & Core Advantages
The 6307-RS1/C3 is a metric single row deep groove ball bearing engineered for reliable performance in demanding industrial applications. Its sealed construction provides robust protection against contaminants, while the C3 radial internal clearance makes it exceptionally suitable for applications with thermal expansion or where interference fits are used. This bearing is designed to handle significant radial loads and offers high operational stability, making it a versatile and durable choice for a wide range of machinery.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6307 | Basic bearing series, indicating a medium duty, single row deep groove ball bearing with 35mm bore, 80mm OD, and 21mm width. |
| RS1 | Designates a synthetic rubber contact seal on one side of the bearing. This provides superior sealing effectiveness compared to non-contact shields, protecting against moisture and particulate contamination. |
| /C3 | Indicates a greater than normal radial internal clearance. This is critical for applications involving high operational temperatures, shaft expansion, or heavy interference fits, preventing premature failure due to excessive preload. |
6307-RS1/C3 Bearing Structural Features & Performance Benefits
- Robust Sealed Design: The RS1 contact seal effectively retains lubrication and excludes contaminants like dust and moisture, significantly extending bearing service life and enabling use in harsh environments. This contributes to a low-maintenance solution.
- Optimized Internal Clearance: The C3 clearance group provides operational flexibility. It accommodates thermal expansion of the shaft and housing, ensuring stable performance and preventing seizure under thermal or fitting stresses.
- High Load Capacity: Manufactured from high-grade chrome steel for both rings and balls, this bearing delivers a high dynamic load rating of 7509 lbf and a static load rating of 4339 lbf, ensuring reliability under substantial radial loads.
- Precision and Stability: Built to ABEC 1 | ISO P0 tolerance class, it offers excellent running accuracy for general industrial applications, contributing to smooth operation and reduced vibration.
6307-RS1/C3 Bearing Typical Application Areas
The 6307-RS1/C3 is ideally suited for a broad spectrum of industrial machinery where contamination protection and accommodation for thermal expansion are paramount. Common applications include:
- Electric Motors and Gearboxes
- Industrial Pumps and Compressors
- Material Handling Equipment (Conveyors, Pulleys)
- Agricultural Machinery
- General Industrial Machinery requiring robust, sealed bearing solutions.
