6305-2RS1 Bearing Product Overview & Core Advantages
The 6305-2RS1 is a metric single row deep groove ball bearing designed for exceptional performance in demanding applications. Engineered with sealed construction, it effectively protects against contaminant ingress, ensuring long service life and reliability. This bearing excels at handling radial loads and moderate axial loads in both directions. Manufactured to P6 tolerance class, it offers high running accuracy, making it ideal for applications requiring precise operation and consistent performance. Its compact design and robust construction provide a reliable solution for a wide range of industrial machinery.
6305-2RS1 Bearing Model Code Explained, Specifications & Naming Convention
The model number 6305-2RS1 can be broken down as follows:
- 63: Series designation, indicating a medium width and medium diameter series.
- 05: Bore diameter code. The bore diameter is calculated as 05 x 5 = 25 mm.
- 2RS1: Signifies that the bearing is equipped with two contact seals (RS1 type) made of Nitrile Rubber (NBR). These seals provide superior protection against dust and moisture compared to non-contact shields.
6305-2RS1 Bearing Structural Features & Performance Benefits
The performance of the 6305-2RS1 is derived from its specific construction:
- High Load Capacity & Rigidity: The single row deep groove raceway and high-quality chrome steel construction provide a high radial dynamic load rating of 5261 lbf and radial static load rating of 2608 lbf, ensuring dependable performance under significant stress.
- Sealed & Pre-Lubricated for Long Life: The two contact seals (2RS1) effectively retain the factory-applied grease lubricant and exclude contaminants. This creates a maintenance-free solution, reducing downtime and extending bearing service intervals.
- Optimized for Speed & Precision: The stainless steel cage ensures low friction and stable operation at the limiting speed of 7,500 rpm. Combined with the P6 tolerance class and standard CN radial internal clearance, this bearing delivers smooth, quiet, and precise rotation.
- Broad Operating Range: With a specified operating temperature range of -30°C to 120°C, this bearing is suitable for use in diverse environmental conditions.
6305-2RS1 Bearing Typical Application Areas
The 6305-2RS1 is a versatile component found in numerous industries and equipment, including:
- Electric Motors and Generators
- Gearboxes and Power Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Equipment (Conveyors, Fans)
- Agricultural Machinery
- Automotive Components (Alternators, Starters)
