6004-2RS1 Bearing Product Overview & Core Advantages
The 6004-2RS1 is a single row deep groove ball bearing featuring integral contact seals on both sides. Engineered for radial load applications, it offers a compact design and reliable performance in a wide range of industrial settings. Its key advantages include effective contamination exclusion, simplified assembly, and consistent operation, making it a versatile and cost-effective solution for general machinery.
Model Code Breakdown
| Code Segment | Description | Technical Significance |
|---|---|---|
| 6004 | Basic Bearing Number | Defines the standard metric dimensions: 20mm bore, 42mm OD, 12mm width. |
| 2RS1 | Seal Designation | Indicates the bearing is fitted with two (2) RS1-type contact seals made of Nitrile Rubber (NBR). This provides superior protection against contaminants like dust and moisture. |
6004-2RS1 Bearing Structural Features & Performance Benefits
- Robust Sealing: The 2RS1 contact seals effectively shield the internal rolling elements and raceways from solid and liquid contaminants, significantly extending bearing service life in harsh environments.
- Optimized Load Capacity: As a single row deep groove ball bearing, it is primarily designed to support high radial loads. The deep, continuous raceway grooves also accommodate moderate axial loads in both directions.
- Precision & Reliability: Manufactured to ABEC 1 | ISO P0 tolerance class with a standard CN radial internal clearance, ensuring consistent performance and smooth operation for general applications.
- Material Integrity: Constructed entirely from chrome steel (rings, balls, and cage), providing excellent durability, wear resistance, and a long operational lifespan.
- Maintenance Simplicity: The sealed and pre-lubricated design is typically maintenance-free, reducing the need for re-lubrication and lowering overall lifecycle costs.
6004-2RS1 Bearing Typical Application Areas
This bearing is widely used across various industries due to its versatility and sealed protection. Common applications include:
- Electric Motors and Generators
- Gearboxes and Transmission Systems
- Industrial Fans and Blowers
- Material Handling Equipment (e.g., Conveyors)
- Agricultural Machinery
- Automotive Components (e.g., alternators, water pumps)
- General Machinery and Appliances
