ET2216 ZZ Bearing Product Overview & Core Advantages
The ET2216 ZZ is a metric single row deep groove ball bearing engineered for reliable performance in compact spaces. This shielded bearing is designed to handle primarily radial loads and is characterized by its high precision ABEC-1 tolerance class. Its key advantages include a compact cross-section with a 4 mm width, making it ideal for applications where space is at a premium, and robust construction using chrome steel rings and balls for durability. The inclusion of stainless steel shields (ZZ) provides effective contamination protection, enhancing operational life and reliability.
ET2216 ZZ Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| ET2216 | Bearing series and size designation: 16 mm bore, 22 mm outside diameter. |
| ZZ | Signifies the presence of non-contact steel shields on both sides. This provides excellent protection against dust and debris while minimizing friction and heat generation. |
ET2216 ZZ Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: Manufactured to ABEC-1 tolerance standards, this bearing ensures smooth, precise rotation and consistent performance, contributing to overall system accuracy.
- Effective Sealing: The ZZ shields protect the internal components from contaminants, significantly extending the bearing's service life and reducing the risk of premature failure in dusty environments.
- Optimized Load Capacity: The deep groove raceway and chrome steel construction are designed to handle substantial radial dynamic loads (218 lbf) and radial static loads (140 lbf) efficiently.
- Compact & Lightweight Design: With a minimal width of 4 mm and a weight of just 3.7 g, this bearing is an optimal solution for lightweight and miniaturized assemblies without sacrificing performance.
