6307-2RS1/C3HT Bearing Product Overview & Core Advantages
The 6307-2RS1/C3 is a single row deep groove ball bearing designed for robust performance in a wide range of industrial applications. Its key advantage lies in its ability to accommodate significant radial loads and moderate axial loads in both directions. The bearing features integral contact seals (2RS1) for effective contamination protection and is supplied with a greater than standard radial internal clearance (C3), making it suitable for applications involving thermal expansion or where shaft fits may cause clearance reduction. This combination delivers a reliable, long-lasting solution for demanding environments.
6307-2RS1/C3HT Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6307 | Basic Bearing Series & Size | Standard metric dimension series with 35mm bore, 80mm OD, and 21mm width. |
| 2RS1 | Sealing Type | Features two integral NBR rubber contact seals on both sides, providing excellent protection against contaminants and retaining lubricant. |
| C3 | Radial Internal Clearance | Indicates a greater than normal radial internal clearance, ideal for applications with thermal gradients, interference fits, or where reduced friction is desired. |
6307-2RS1/C3HT Bearing Structural Features & Performance Benefits
- Deep Groove Raceway & High-Quality Steel: The optimized raceway geometry and construction from chrome steel rings, balls, and cage enable high radial load capacity and smooth operation.
- Superior Sealing with 2RS1: The rubber contact seals effectively shield the bearing interior from dust, dirt, and moisture, significantly extending service life and reducing maintenance needs in harsh conditions.
- Optimized Internal Clearance (C3): The C3 clearance provides operational flexibility, accommodating shaft expansion and certain misalignments without inducing excessive preload, which helps maintain bearing performance and longevity.
- Standard Precision & High Limiting Speed: Manufactured to ABEC 1 | ISO P0 tolerance class, ensuring consistent quality. The limiting speed of 8,500 rpm makes it suitable for a broad spectrum of high-speed applications.
