S6904 2rs Bearing Product Overview & Core Advantages
The S6904 2RS is a single row deep groove ball bearing designed for high-performance applications requiring reliable radial load capacity and consistent operation. Constructed entirely from stainless steel (rings, balls, and cage), it offers excellent corrosion resistance. A key feature is its sealed design (2RS), which effectively shields the bearing from contaminants and retains lubrication, making it suitable for applications where maintenance is difficult or where cleanliness is critical. Its compact dimensions (20mm bore, 37mm OD, 9mm width) and ABEC-1 precision class make it an ideal choice for compact, precision assemblies.
S6904 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Significance & Benefit |
|---|---|---|
| S | Stainless Steel | Indicates the bearing rings and rolling elements are made from stainless steel, providing superior corrosion resistance. |
| 2RS | Contact Seals on Both Sides | Features rubber contact seals on both sides, offering excellent protection against dust, moisture, and other contaminants. This also helps to retain the pre-applied lubricant, contributing to a longer service life with minimal maintenance. |
S6904 2rs Bearing Structural Features & Performance Benefits
- Robust Stainless Steel Construction: The use of stainless steel for all critical components ensures high corrosion resistance and reliable performance in harsh or wash-down environments, expanding its application range.
- Effective Sealing: The 2RS contact seals provide a high level of ingress protection (IP rating equivalent), making the bearing suitable for contaminated or humid conditions and reducing the risk of premature failure.
- Precision and Reliability: Manufactured to ABEC-1 tolerance class with a C0 radial internal clearance, this bearing ensures smooth and quiet operation, low vibration, and consistent performance in a wide range of applications.
- Optimized Load Capacity: The deep groove raceway and single-row design are optimized to handle significant radial loads (dynamic: 1291 lbf, static: 745 lbf) and moderate axial loads in both directions.
