6004-2RSH/C3 GJN Bearing Product Overview & Core Advantages
The 6004-2RSH/C3 GJN is a high-performance sealed deep groove ball bearing engineered for demanding industrial applications. This single row bearing excels in handling significant radial loads while offering moderate axial load capacity in both directions. Its key advantages include a generous C3 radial internal clearance for thermal expansion management in high-speed or high-temperature operations, and integrated sealing (2RSH) providing superior protection against contaminants. Manufactured to ABEC 1 | ISO P0 tolerance standards, it delivers reliable precision and long service life in compact installations.
6004-2RSH/C3 GJN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6004 | Basic bearing series, 20mm bore diameter, 42mm OD, 12mm width |
| 2RSH | Double rubber contact seals on both sides for excellent contamination exclusion |
| C3 | Greater radial internal clearance than normal group, suitable for applications with thermal expansion |
| GJN | Polyurea grease filling, suitable for high-temperature applications up to 120°C |
6004-2RSH/C3 GJN Bearing Structural Features & Performance Benefits
Optimized Sealing System: The 2RSH rubber contact seals provide superior protection against dust, moisture, and other contaminants while maintaining low friction characteristics, extending bearing service life in harsh environments.
Enhanced Thermal Performance: The C3 radial clearance accommodates differential thermal expansion between shaft and housing, preventing preload conditions that could lead to premature failure in high-speed or temperature-varying applications.
Premium Material Construction: Manufactured entirely from chrome steel for rings, balls, and cage, ensuring consistent material properties, excellent wear resistance, and dimensional stability under load.
High-Speed Capability: With a limiting speed of 17,000 rpm, this bearing is engineered for demanding rotational applications, supported by the optimized cage design and high-temperature grease.
