6004-2RS1NR/C3 Bearing Product Overview & Core Advantages
The 6004-2RS1NR/C3 is a single row deep groove ball bearing designed for exceptional performance in demanding applications. This precision bearing features integrated seals and a snap ring, offering reliable radial load capacity and simplified installation. Its optimized internal geometry and C3 radial internal clearance ensure stable operation across a wide temperature range, making it an ideal choice for applications requiring high reliability and long service life.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6004 | Standard bearing series designation, indicating a metric deep groove ball bearing with a 20mm bore, 42mm OD, and 12mm width. |
| 2RS1 | Bearing is equipped with two contact seals (RS1 type) on both sides, providing superior protection against contaminants and retention of lubricant. |
| NR | The outer ring features a snap ring groove and is supplied with a fitted snap ring. This facilitates secure axial location within a housing, simplifying design and assembly. |
| C3 | Specifies a greater than normal radial internal clearance. This is beneficial for applications with significant thermal expansion or where interference fits are used. |
6004-2RS1NR/C3 Bearing Structural Features & Performance Benefits
- Robust Sealing & Protection: The dual contact seals (2RS1) effectively shield the bearing internals from dust, moisture, and other contaminants while retaining lubricant, significantly enhancing operational reliability and lifespan in harsh environments.
- Simplified Axial Location: The integrated snap ring (NR) on the outer ring allows for secure and straightforward axial positioning within a housing, eliminating the need for complex housing shoulders and reducing assembly time and cost.
- Optimized Internal Clearance: The C3 radial internal clearance provides operational stability in applications prone to thermal expansion or where tight interference fits are applied, preventing excessive preload and potential bearing seizure.
- High-Quality Construction: Manufactured from chrome steel for rings, balls, and cage, this bearing ensures high strength, durability, and consistent performance under dynamic and static radial loads.
6004-2RS1NR/C3 Bearing Typical Application Areas
This versatile bearing is commonly specified in a wide range of industrial and automotive applications, including:
- Electric Motors and Generators
- Gearboxes and Transmission Systems
- Industrial Pumps and Compressors
- Agricultural Machinery
- Material Handling Equipment
- Automotive Components (e.g., alternators, idlers)
