S6702 2rs Bearing Product Overview & Core Advantages
The S6702 2RS is a metric miniature ball bearing designed for applications demanding compact size, reliable performance, and corrosion resistance. As a single row deep groove ball bearing, it excels at handling radial loads while also accommodating moderate axial loads in both directions. Its sealed construction (2RS) and stainless steel components make it an ideal choice for environments requiring protection from contaminants and moisture, ensuring long-term operational reliability and reduced maintenance needs.
S6702 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| S6702 | Basic bearing designation indicating a metric, miniature deep groove ball bearing series with a 15mm bore, 21mm OD, and 4mm width. | Defines the core bearing dimensions and series. |
| 2RS | Contact rubber seals on both sides of the bearing. | Provides effective protection against dust, moisture, and other contaminants, retaining lubricant for extended service life and enabling use in harsh environments. |
S6702 2rs Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With a 4mm width and a weight of only 3.6 grams, this bearing is engineered for space-constrained applications without sacrificing performance.
- Corrosion Resistance: Manufactured entirely from stainless steel (rings, balls, and cage), it offers excellent resistance to rust and corrosion, suitable for a wide temperature range from -86 to 230 °F.
- Sealed for Protection & Longevity: The 2RS double seals effectively shield the internal components, retaining the factory-applied lubricant and preventing the ingress of contaminants. This design supports a limiting speed of 9,900 rpm and contributes to a maintenance-free operation in many applications.
- Precision & Load Capacity: Built to ABEC-1 tolerance class with a C0 radial internal clearance, it provides reliable and smooth operation. It offers a radial dynamic load rating of 190 lbf and a radial static load rating of 118 lbf for its compact size.
