6004-2RSH /C3GJN Bearing Product Overview & Core Advantages
The 6004-2RSH /C3GJN is a single row deep groove ball bearing designed for high reliability and performance in demanding applications. This sealed bearing excels at handling radial loads and moderate axial loads in both directions. Its key advantages include a robust sealed construction for contaminant exclusion, a C3 radial internal clearance suitable for applications with thermal expansion, and compliance with ABEC 1 | ISO P0 precision standards, making it a versatile and dependable choice for a wide range of industrial machinery.
6004-2RSH /C3GJN Bearing Model Code Explained, Specifications & Naming Convention
- 6004: Basic designation indicating a metric, single row deep groove ball bearing with a 20mm bore and 42mm outside diameter.
- 2RSH: Signifies that the bearing is fitted with two (2) contact seals (RSH) on both sides. The RSH seal is made of NBR rubber and provides effective protection against contaminants and moisture retention.
- C3: Denotes a radial internal clearance greater than the Normal (CN) group. This is advantageous where interference fits or operational temperature differentials are expected.
- GJN: Indicates the bearing is pre-lubricated with a specific high-quality grease. This grease offers a wide operating temperature range and contributes to the bearing's long service life and low maintenance requirements.
6004-2RSH /C3GJN Bearing Structural Features & Performance Benefits
The performance of the 6004-2RSH /C3GJN is derived from its carefully selected components and design. The chrome steel rings and balls provide high strength and durability, supporting the dynamic load rating of 2113 lbf. The contact seals (2RSH) are a critical feature, offering superior protection against dust, dirt, and moisture compared to non-contact shields, thereby extending bearing life in harsh environments. The C3 clearance ensures optimal performance under conditions that may cause thermal expansion of the shaft or housing. Finally, the pre-applied GJN grease ensures immediate and reliable lubrication from the first rotation, supporting smooth operation up to the limiting speed of 17,000 rpm.
6004-2RSH /C3GJN Bearing Typical Application Areas
This bearing's combination of sealing, clearance, and lubrication makes it suitable for a broad spectrum of applications, including:
- Electric Motors and Gearboxes
- Industrial Pumps and Compressors
- Material Handling Equipment (e.g., conveyor rollers)
- Agricultural Machinery
- Automotive Components (e.g., alternators, idler pulleys)
