6004-2RS/C3 GJN Bearing Product Overview & Core Advantages
The 6004-2RS/C3 GJN is a single row deep groove ball bearing designed for robust performance in demanding applications. This metric bearing excels at handling primarily radial loads and offers a compact design with a 20mm bore. Its key advantages include a sealed construction for contamination protection and a C3 radial internal clearance for stable operation under thermal expansion, making it a reliable choice for general industrial machinery requiring high reliability and long service life.
6004-2RS/C3 GJN Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning | Advantage |
|---|---|---|
| 2RS | Contact rubber seals on both sides | Provides excellent protection against contaminants and retains lubricant, enhancing bearing life in dirty environments. |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion in applications with high operating temperatures or heavy loads, preventing premature failure. |
| GJN | Pre-lubricated with a specific high-quality grease | Offers ready-to-install, maintenance-free operation for a wide temperature range (-30°C to 120°C). |
6004-2RS/C3 GJN Bearing Structural Features & Performance Benefits
- Sealed Design: The double-sided contact seals (2RS) effectively shield the chrome steel rolling elements and raceways from dust, moisture, and other contaminants, significantly increasing operational reliability.
- Optimized Internal Clearance: The C3 clearance provides operational stability in applications prone to thermal expansion or where fit conditions create a tighter internal environment, preventing binding and reducing friction.
- Robust Load Capacity: With a dynamic load rating of 2113 lbf and a static load rating of 1135 lbf, this bearing is engineered to handle significant radial loads consistently.
- Pre-Lubricated for Longevity: Filled with GJN grease, the bearing is lubricated for life under normal operating conditions, eliminating the need for re-lubrication and reducing maintenance costs.
- Precision Engineering: Manufactured to ABEC 1 | ISO P0 tolerance class, it ensures consistent performance and smooth operation for a wide range of industrial applications.
6004-2RS/C3 GJN Bearing Typical Application Areas
