S6818zz Bearing Product Overview & Core Advantages
The S6818zz is a single row deep groove ball bearing engineered for precision and reliability in demanding applications. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its key advantage lies in its ability to efficiently handle radial loads, making it an ideal choice for compact designs requiring high operational integrity. The inclusion of shielded seals (zz) provides robust protection against contamination, enhancing its service life and making it suitable for applications where maintenance access is limited.
S6818zz Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| S | Stainless Steel construction for enhanced corrosion resistance. |
| 68 | Series designation indicating a very thin cross-section relative to its bore diameter. |
| 18 | Bore diameter code for a 90 mm bore. |
| zz | Indicates the bearing is shielded on both sides. This provides effective protection against dust and other particulates while minimizing friction. |
S6818zz Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With an outside diameter of 115 mm and a width of just 13 mm, this bearing offers a high load capacity within a minimal envelope, perfect for space-constrained applications. Its low weight of 279 g contributes to reduced rotational inertia.
- Robust Load Capacity: Engineered to handle significant radial dynamic load ratings of 3703 lbf and radial static load ratings of 3945 lbf, ensuring reliable performance under stress.
- Precision & Smooth Operation: Manufactured to ABEC-1 tolerance class with a C0 radial internal clearance (0.012mm to 0.036mm), guaranteeing consistent running accuracy and low vibration.
- Enhanced Service Life: The stainless steel cage and components, combined with shielded protection, reduce wear and the risk of premature failure from corrosion or contamination.
- Wide Temperature Range: Operates effectively in temperatures from -86 to 230 °F, making it versatile for various environmental conditions.
S6818zz Bearing Typical Application Areas
