6300-2RS1/C3 GJN Bearing Product Overview & Core Advantages
The 6300-2RS1/C3 GJN is a sealed single row deep groove ball bearing engineered for high reliability in demanding applications. This metric bearing is characterized by its ability to handle significant radial loads and moderate axial loads in both directions. Its sealed construction and C3 radial internal clearance make it an excellent choice for applications requiring robust performance, extended service life, and minimal maintenance. Manufactured to ABEC 1 | ISO P0 tolerance standards, it ensures consistent and precise operation.
6300-2RS1/C3 GJN Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| 2RS1 | Contact seals on both sides, made from Nitrile Rubber (NBR). | Provides effective protection against contaminants and retains lubricant, enhancing bearing life in dirty environments. |
| C3 | Greater than normal radial internal clearance. | Ideal for applications with thermal expansion or where interference fits are used, preventing premature failure due to excessive preload. |
| GJN | Pre-lubricated with a specific polyurea grease. | Offers a wide temperature range (-30°C to +120°C), good speed capability, and long-term lubrication, making the bearing ready-to-install and maintenance-free. |
6300-2RS1/C3 GJN Bearing Structural Features & Performance Benefits
- Robust Sealed Design: The 2RS1 contact seals effectively shield the internal components from dust, moisture, and other contaminants, while securely retaining the factory-applied grease. This results in a highly reliable, maintenance-free bearing solution.
- Optimized Internal Clearance: The C3 clearance is a critical feature for applications involving thermal gradients or tight press fits. It accommodates dimensional changes without inducing detrimental internal stresses, ensuring smooth operation and extended service life.
- High-Quality Material & Construction: All critical components, including rings, balls, and cage, are manufactured from chrome steel, providing high strength, wear resistance, and durability. The single-row deep groove raceway is optimized for high radial load capacity.
- Ready-to-Use Lubrication: The GJN grease filling is selected for its stability across the specified temperature range and its contribution to achieving the bearing's limiting speed of 22,000 rpm.
6300-2RS1/C3 GJN Bearing Typical Application Areas
The 6300-2RS1/C3 GJN is a versatile component suited for a wide range of industrial machinery and equipment where reliability and minimal maintenance are paramount. Key application areas include:
- Electric Motors and Small Gearboxes
- Industrial Fans and Blowers
