6306-2RS1/C4 Bearing Product Overview & Core Advantages
The 6306-2RS1/C4 is a metric single row deep groove ball bearing engineered for high-performance applications requiring reliable operation under radial loads. Featuring integrated contact seals (2RS1) and an optimized C4 radial internal clearance, this bearing offers superior contamination protection and stable performance across a wide temperature range. Its robust construction from chrome steel components ensures excellent durability, making it an ideal solution for industrial machinery demanding consistent, long-term service with minimal maintenance.
6306-2RS1/C4 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6306 | Basic bearing series designation, indicating a medium-duty, single row deep groove ball bearing with 30mm bore, 72mm OD, and 19mm width. |
| 2RS1 | Bearing is equipped with two contact seals (one on each side) providing superior protection against contaminants and retaining lubricant. |
| C4 | Specifies a greater radial internal clearance than normal (C0), suitable for applications with significant thermal expansion or where interference fits are used. |
6306-2RS1/C4 Bearing Structural Features & Performance Benefits
- Sealed & Protected Design: The 2RS1 contact seals effectively shield the bearing interior from dust, moisture, and other contaminants, while retaining grease, significantly extending service life in harsh environments.
- Optimized Internal Clearance: The C4 radial clearance accommodates thermal expansion and interference fits, preventing excessive preload and ensuring smooth, reliable operation under varying thermal conditions.
- Robust Load Capacity: With a dynamic load rating of 6002 lbf and static load rating of 3372 lbf, this bearing handles substantial radial loads, providing reliable support for rotating shafts.
- Precision & Consistency: Manufactured to ABEC 1 | ISO P0 tolerance class, it ensures consistent running accuracy and low vibration for general industrial applications.
- Wide Operating Range: A temperature range of -30°C to 120°C allows for use in diverse climates and operating conditions.
6306-2RS1/C4 Bearing Typical Application Areas
- Electric Motors and Gearboxes
- Industrial Fans and Blowers
- Material Handling Conveyors
- Agricultural Machinery
- General Industrial Machinery requiring sealed, reliable bearing solutions
