6306-2RS2/C3VT312 Bearing Product Overview & Core Advantages
The 6306-2RS2/C3 is a sealed single row deep groove ball bearing engineered for reliable performance in demanding applications. This metric bearing features integrated contact seals (2RS2) for superior contamination protection and is manufactured to ABEC 1 precision standards. Its key advantages include the ability to handle significant radial loads and moderate axial loads in both directions, making it a versatile and robust solution. The predefined C3 radial internal clearance ensures optimal performance in applications with thermal expansion or where fit-up conditions require it.
6306-2RS2/C3VT312 Bearing Model Code Explained, Specifications & Naming Convention
- 6306: Basic designation indicating a medium-duty, single row deep groove ball bearing with a 30mm bore and 72mm outside diameter.
- 2RS2: Signifies double lip seals on both sides. These provide enhanced sealing effectiveness compared to standard shields or single lip seals, offering superior protection against contaminants and moisture retention.
- C3: Denotes a greater than normal radial internal clearance. This is essential for applications involving thermal expansion, interference fits, or where operational conditions lead to a reduction in internal clearance.
6306-2RS2/C3VT312 Bearing Structural Features & Performance Benefits
The bearing's performance is derived from its robust construction. The single row deep groove raceway geometry is optimized for high radial load capacity. The use of high-grade chrome steel for all critical components (rings, balls, cage) ensures high durability and resistance to wear. The double lip contact seals (2RS2) are a critical feature, effectively retaining lubrication and excluding harmful contaminants, which significantly extends service life and enables maintenance-free operation in many environments. The C3 clearance provides operational stability under varying thermal and mechanical conditions, preventing premature failure due to excessive preload.
6306-2RS2/C3VT312 Bearing Typical Application Areas
This bearing is widely used across various industries due to its versatility and reliability. Common applications include:
- Electric Motors and Generators
- Industrial Gearboxes and Power Transmission Systems
- Material Handling Equipment (conveyors, pulleys)
- Agricultural Machinery
- Automotive Components (pumps, alternators)
