6903 2rs Bearing Product Overview & Core Advantages
The 6903 2RS is a single row deep groove ball bearing designed for reliable performance in demanding applications. This metric bearing features integral contact seals (2RS) on both sides, providing superior protection against contaminants and retaining lubricant. Engineered with chrome steel rings and balls and a stainless steel cage, it offers excellent durability and consistent operation. Its compact design, with a 17 mm bore and 30 mm outside diameter, makes it an ideal choice for applications requiring a space-saving solution with robust radial load capacity.
6903 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6903 | Basic bearing series and size designation (17mm bore, 30mm OD, 7mm width). |
| 2RS | Indicates the bearing is fitted with two rubber contact seals, one on each side. This provides effective sealing against dust, moisture, and other contaminants. |
6903 2rs Bearing Structural Features & Performance Benefits
- Sealed for Protection and Longevity: The dual rubber contact seals (2RS) effectively shield the internal components from contaminants, making the bearing suitable for dirty or humid environments. This design also helps to retain lubricant, extending service intervals and promoting a longer operational life.
- Robust Load Handling: Manufactured from high-grade chrome steel, this bearing is capable of handling significant radial dynamic loads (up to 1033 lbf) and radial static loads (up to 576 lbf). The deep groove raceway is optimized for radial loads but can also accommodate moderate axial loads in both directions.
- Stable and Reliable Operation: The inclusion of a stainless steel cage ensures precise ball guidance and spacing, which minimizes friction and heat generation, contributing to smooth running and high limiting speeds (26,000 rpm).
- Standardized Precision: Conforming to ABEC-1 tolerance class and C0 radial internal clearance, this bearing offers a reliable balance of precision and performance for a wide range of industrial applications.
