6004-2RSH/MT37 Bearing Product Overview & Core Advantages
The 6004-2RSH is a single row deep groove ball bearing designed for exceptional reliability in demanding applications. Its key advantage lies in its sealed construction (2RSH), which provides robust protection against contamination and retains lubrication, enabling long service life with minimal maintenance. Engineered to primarily handle radial loads, this bearing features a metric design with a 20 mm bore and is manufactured from high-grade chrome steel for consistent performance and durability. It is an ideal, cost-effective solution for a wide range of industrial machinery requiring a dependable, pre-lubricated, and sealed ball bearing.
6004-2RSH/MT37 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Interpretation | Technical Significance |
|---|---|---|
| 6004 | Basic Bearing Number | Denotes a single row deep groove ball bearing with a 20mm bore and 42mm outside diameter. |
| 2RSH | Seal Type | Indicates contact seals on both sides. The "RSH" suffix typically signifies NBR (Nitrile Rubber) seals with a steel reinforcement, offering superior sealing effectiveness and resistance to grease wash-out compared to standard non-contact shields. |
6004-2RSH/MT37 Bearing Structural Features & Performance Benefits
- Robust Sealing: The 2RSH contact seals effectively prevent the ingress of contaminants like dust and moisture, while also retaining the factory-applied grease. This significantly enhances bearing life in harsh environments and supports a maintenance-free operational philosophy.
- High Load Capacity: The deep groove raceway and optimized internal geometry enable the bearing to carry significant radial dynamic load ratings (2113 lbf) and moderate axial loads in both directions.
- Reliable Performance: Manufactured from chrome steel for both rings and balls, the bearing ensures high strength and resistance to wear. The standard CN radial internal clearance and ABEC 1 (ISO P0) tolerance class guarantee consistent and reliable performance for most industrial applications.
- Broad Operating Range: With a specified temperature range from -30°C to 120°C, this bearing is suitable for a wide array of operating conditions.
