6305-2RS1/C3 Bearing Product Overview & Core Advantages
The 6305-2RS1/C3 is a single row deep groove ball bearing designed for reliable performance in demanding applications. This sealed bearing excels at handling radial loads and moderate axial loads in both directions. Its key advantages include robust construction with chrome steel components, a generous C3 radial internal clearance suitable for thermal expansion scenarios, and integrated sealing for contamination protection. This combination makes it an excellent choice for applications requiring high reliability and extended service life without relubrication.

6305-2RS1/C3 Bearing Structural Features & Performance Benefits
Deep Groove Geometry: The uninterrupted raceways enable smooth operation under radial loads and combined loads, making it versatile for various mounting configurations.
Contact Seals (2RS1): Rubber seals on both sides provide effective protection against dust, moisture, and other contaminants while retaining lubricant, significantly extending bearing service life in harsh environments.
C3 Internal Clearance: The optimized radial internal clearance accommodates shaft and housing fits, as well as thermal expansion during operation, preventing premature failure due to excessive preload.
Chrome Steel Construction: All critical components (rings, balls, cage) are manufactured from high-grade chrome steel, ensuring excellent durability and consistent performance under the specified temperature range of -30°C to 120°C.
6305-2RS1/C3 Bearing Typical Application Areas
- Electric Motors: Ideal for industrial motors requiring sealed, maintenance-free operation
- Agricultural Machinery: Suitable for equipment operating in dusty or contaminated environments
- Material Handling Systems: Conveyor rollers, pulley systems, and other transmission components
- Industrial Pumps & Fans: Applications requiring reliable performance with moderate speeds
- General Industrial Machinery: Various machinery where radial load capacity and contamination protection are critical
