6306-2RS1/C3WT Bearing Product Overview & Core Advantages
The 6306-2RS1/C3WT is a single row deep groove ball bearing designed for robust performance in demanding applications. Its key advantage lies in its ability to efficiently handle radial loads while offering operational reliability through its sealed construction. The bearing features 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 a cost-effective solution for general industrial use where precision, durability, and sealed protection are required.
6306-2RS1/C3WT Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| -2RS1 | Contact rubber seals on both sides | Provides effective protection against contaminants and retains lubricant, enhancing bearing life. |
| /C3 | Greater than normal radial internal clearance | Accommodates thermal expansion and interference fits, preventing operational issues due to tightness. |
| WT | Wide Temperature Range | Indicates suitability for the specified operating temperature range of -30°C to 120°C. |
6306-2RS1/C3WT Bearing Structural Features & Performance Benefits
- Sealed Design: The 2RS1 contact seals on both sides effectively shield the internal components from dust, moisture, and other contaminants. This design significantly extends service life and reduces maintenance needs in harsh environments.
- Optimized Internal Clearance: The C3 clearance provides extra space between the rolling elements and raceways. This is critical for applications involving high speeds or where shaft and housing fits may reduce the operational clearance, preventing premature failure due to excessive heat and friction.
- Robust Load Capacity: With a dynamic load rating of 6002 lbf and a static load rating of 3372 lbf, this bearing is engineered to handle significant radial loads, ensuring reliable performance under strenuous conditions.
- High-Quality Material: Constructed entirely from chrome steel for the rings, balls, and cage, the bearing offers high strength, wear resistance, and durability, contributing to a long operational lifespan.
6306-2RS1/C3WT Bearing Typical Application Areas
This versatile bearing is commonly specified in a wide range of industrial machinery, including:
- Electric Motors and Gearboxes
- Industrial Pumps and Fans
- Material Handling Equipment (e.g., conveyor systems)
- Agricultural Machinery
- Automotive Components (e.g., alternators, idler pulleys)
