6305-RS1/C3 Bearing Product Overview & Core Advantages
The 6305-RS1/C3 is a single row deep groove ball bearing designed for exceptional performance in demanding applications. This sealed bearing features a robust construction that provides reliable operation under radial loads and moderate axial loads in both directions. Its key advantages include a high limiting speed and a generous C3 radial internal clearance, making it suitable for applications where thermal expansion is a concern. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers a cost-effective solution without compromising on reliability and longevity.
6305-RS1/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6305 | Standard series designation for a medium-duty deep groove ball bearing with a 25mm bore diameter. |
| RS1 | Indicates the bearing is fitted with a synthetic rubber seal on one side. This provides effective protection against contaminants while retaining lubricant. |
| /C3 | Specifies a greater than normal radial internal clearance. This is ideal for applications with high operational temperatures or where interference fits are used, preventing preload and ensuring smooth operation. |
6305-RS1/C3 Bearing Structural Features & Performance Benefits
Robust Construction & High Load Capacity: Built entirely from chrome steel for the rings, balls, and cage, this bearing delivers high strength and durability. It features a deep groove raceway geometry that enables it to support significant radial dynamic loads (4631 lbf) and moderate axial loads.
Sealed for Protection & Long Life: The RS1 seal effectively shields the internal components from dust, moisture, and other contaminants. This design significantly extends the bearing's service life and reduces maintenance requirements in harsh environments.
Optimized for Thermal Expansion: The C3 clearance is a critical feature that accommodates dimensional changes due to thermal expansion during operation, preventing binding and reducing friction and heat generation, which contributes to a high limiting speed of 11,000 rpm.
Precision & Compliance: Manufactured to ABEC 1 precision standards, it ensures consistent performance and smooth operation. The bearing is also compliant with ROHS and REACH regulations.
6305-RS1/C3 Bearing Typical Application Areas
