S6811 2rs Bearing Product Overview & Core Advantages
The S6811 2RS is a metric single row deep groove ball bearing designed for high-performance applications requiring compact design and reliable operation. Featuring stainless steel construction throughout (rings, balls, cage) and integrated seals (2RS), it offers excellent corrosion resistance and protection against contamination. This bearing is engineered to handle primarily radial loads with high precision (ABEC-1 tolerance) and is suitable for a wide operating temperature range. Its compact cross-section (9mm width) makes it ideal for space-constrained applications while maintaining robust dynamic and static load capacities.
S6811 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| S6811 | Basic bearing designation with 55mm bore diameter, 72mm outside diameter, and 9mm width | Standard metric dimensions for easy integration |
| 2RS | Bearing with contact seals on both sides | Effective protection against contaminants and moisture retention |
S6811 2rs Bearing Structural Features & Performance Benefits
Stainless Steel Construction: All components (rings, balls, cage) manufactured from stainless steel provides superior corrosion resistance and makes the bearing suitable for harsh environments, including those requiring washdown or exposure to chemicals.
Sealed Design: The 2RS contact seals effectively shield the bearing interior from dust, dirt, and other contaminants while retaining lubrication. This enhances bearing life and reliability in challenging operating conditions.
Precision Performance: Manufactured to ABEC-1 tolerance class with controlled radial internal clearance (C0), this bearing ensures smooth operation, reduced vibration, and consistent performance in precision applications.
High-Speed Capability: With a limiting speed of 9,000 rpm, the bearing is suitable for various high-speed applications. The optimized design and proper lubrication contribute to stable operation at elevated rotational speeds.
