6306-2RS1/C3 Bearing Product Overview & Core Advantages
The 6306-2RS1/C3 is a deep groove ball bearing designed for robust performance in demanding applications. As a metric single row bearing with integral contact seals, it excels at handling primarily radial loads while offering protection against contamination. Its key advantages include reliable operation due to its sealed construction, a C3 radial internal clearance suitable for applications with thermal expansion, and compliance with international standards including ROHS and REACH, making it a versatile and dependable choice for industrial machinery.
Model Code Breakdown
- 6306: Basic designation for a medium-duty, single row deep groove ball bearing with a 30mm bore.
- -2RS1: Signifies that the bearing is fitted with rubber contact seals on both sides. The "RS1" type provides effective protection against dust and moisture ingress.
- /C3: Indicates a greater than normal radial internal clearance. This is beneficial for applications where thermal expansion of the shaft or housing is expected, preventing pre-load and potential bearing failure.
6306-2RS1/C3 Bearing Structural Features & Performance Benefits
The bearing's performance is derived from its precision construction. The single row deep groove raceway is optimized for smooth operation under radial dynamic loads (rated at 6002 lbf). Manufactured from high-grade Chrome Steel for both rings and balls, it ensures durability and a long service life. The sealed design (2RS1) retains lubrication and excludes contaminants, making it suitable for environments where re-lubrication is difficult. The specified C3 clearance group accommodates fits and operating conditions that generate heat, ensuring stable performance across its temperature range of -30°C to 120°C. With an ABEC 1 | ISO P0 tolerance class, it provides reliable performance for a wide range of general industrial applications.
6306-2RS1/C3 Bearing Typical Application Areas
This bearing is commonly found in:
- Electric Motors and Generators
- Industrial Gearboxes
- Material Handling Equipment (Conveyors, Pulleys)
- Agricultural Machinery
- Automotive Components (Pumps, Auxiliary Drives)
