6307-2RS2/C3WT Bearing Product Overview & Core Advantages
The 6307-2RS2/C3WT is a metric single row deep groove ball bearing designed for exceptional performance in demanding applications. Its key advantage lies in its ability to efficiently handle radial loads while offering robust, sealed construction for long service life. The bearing features integrated seals (2RS2) for effective contamination protection and is supplied with a C3 radial internal clearance, making it suitable for applications with thermal expansion or where interference fits are used. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides reliable and precise operation, establishing itself as a versatile and durable solution for industrial machinery.
6307-2RS2/C3WT Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6307 | Basic Bearing Series & Size | Denotes a medium-duty, metric deep groove ball bearing with a 35mm bore, 80mm OD, and 21mm width. |
| 2RS2 | Contact Seals on Both Sides | Indicates the presence of low-friction NBR contact seals on both sides, providing superior protection against dust and moisture ingress compared to non-contact shields. |
| C3 | Radial Internal Clearance | Specifies a greater than normal radial internal clearance. This is critical for applications involving thermal expansion, heavy interference fits, or where operational heat generation is expected. |
| WT | Water Resistant Coating | Signifies that the bearing's exterior features a protective coating to enhance corrosion resistance in humid or washdown environments. |
6307-2RS2/C3WT Bearing Structural Features & Performance Benefits
- Robust Deep Groove Design & High-Quality Materials: The single row, deep groove raceway is manufactured from chrome steel, enabling high radial load capacity (7,509 lbf dynamic / 4,339 lbf static). The use of chrome steel for rings, balls, and cage ensures consistent performance and durability.
- Enhanced Sealing & Contamination Resistance: The 2RS2 double-contact seals effectively retain lubrication and exclude contaminants, significantly extending bearing life in dirty or wet operating conditions. This contributes to the bearing's maintenance-free characteristics.
- Optimized for Thermal & Fit Conditions: The C3 radial clearance prevents pre-loading and potential seizure in applications where shaft or housing fits are tight, or where operational temperatures cause differential expansion.
- Balanced Performance: With a limiting speed of 8,500 rpm and a wide operating temperature range (-30°C to 120°C), this bearing offers a reliable balance of speed capability and thermal stability for a broad range of industrial uses.
6307-2RS2/C3WT Bearing Typical Application Areas
The 6307-2RS2/C3WT is ideally suited for a wide array of industrial machinery and equipment where reliability, sealing, and adaptability to fit conditions are paramount. Key application areas include:
- Electric Motors & Generators
- Industrial Gearboxes & Transmissions
- Material Handling Conveyors
- Agricultural Machinery
- Pumps & Fans
- Construction Equipment
