6905 2rs Bearing Product Overview & Core Advantages
The 6905 2RS is a single row deep groove ball bearing featuring integral contact seals (2RS). Engineered for robust radial load capacity and reliable operation in contaminated environments, this metric bearing is a versatile solution for a wide range of industrial applications. Its compact design, characterized by a 9 mm width, makes it ideal for space-constrained assemblies. Manufactured to ABEC-1 precision tolerances, it delivers consistent performance and high reliability, supported by a radial dynamic load rating of 1577 lbf.
6905 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6905 | The basic bearing designation, indicating a deep groove ball bearing with a 25 mm bore and 42 mm outside diameter. |
| 2RS | Signifies that the bearing is equipped with two integral contact seals, one on each side. These seals provide superior protection against contaminants like dust and moisture, enhancing bearing life and enabling use in demanding conditions. |
6905 2rs Bearing Structural Features & Performance Benefits
- Sealed Construction for Enhanced Durability: The 2RS contact seals are the cornerstone of this bearing's design, effectively shielding the internal components from contaminants. This results in extended service life and reduced maintenance needs, making it a low-maintenance solution.
- Optimized Material Selection: The combination of a chrome steel ring and ball material ensures high load capacity and wear resistance. The stainless steel cage provides excellent corrosion resistance and durability, contributing to stable operation.
- Precision and Reliability: Manufactured to ABEC-1 tolerance class with a C0 radial internal clearance (0.006mm to 0.020mm), this bearing offers predictable performance and smooth running, which is critical for consistent application performance.
- Broad Operating Range: With a temperature range of -30°C to 110°C, this bearing is suitable for various environmental conditions. Its limiting speed of 19,000 rpm allows for use in a wide array of machinery.
