S6808 2rs Bearing Product Overview & Core Advantages
The S6808 2RS is a sealed single row deep groove ball bearing designed for high-performance applications requiring reliable operation under radial loads. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its compact design, with a 7 mm width, makes it ideal for space-constrained assemblies. The bearing is pre-lubricated and features integral contact seals (2RS), providing robust protection against contaminants and enabling long-term, maintenance-free operation in demanding environments.
Model Code Breakdown
| Code Segment | Description | Technical Significance |
|---|---|---|
| S | Stainless Steel | Indicates the bearing rings and balls are made from stainless steel, providing superior corrosion resistance. |
| 6808 | Size Series | Denotes the bearing dimensions: 40 mm bore, 52 mm outside diameter, 7 mm width. |
| 2RS | Seal Type | Signifies double-lip contact seals on both sides. This provides effective sealing against dust, moisture, and other contaminants, retaining lubricant for extended service life. |
S6808 2rs Bearing Structural Features & Performance Benefits
Deep Groove Raceway & Single Row Design: The deep groove geometry of the inner and outer rings is optimized for handling high radial dynamic load ratings (997 lbf). The single-row construction ensures a compact cross-section, contributing to the bearing's low weight of just 35 g.
Full-Complement Stainless Steel Construction: All critical components—rings, balls, and cage—are manufactured from stainless steel. This not only ensures consistent performance and compatibility but also provides excellent resistance to rust and corrosion, making it suitable for harsh or washdown environments.
Integrated Sealing & Pre-Lubrication: The 2RS double-lip seals make the bearing effectively sealed for life. This design prevents lubricant leakage and ingress of contaminants, supporting a maintenance-free operational strategy and enhancing reliability.
Precision & Clearance: Manufactured to ABEC-1 tolerance class with a C0 standard radial internal clearance (0.006mm to 0.020mm), this bearing offers a balance of precision and operational stability for a wide range of general industrial applications.
S6808 2rs Bearing Typical Application Areas
