6217-ZNR Bearing Product Overview & Core Advantages
The 6217-ZNR is a single row deep groove ball bearing designed for robust performance in demanding radial load applications. Its key advantage lies in its shielded design and integrated snap ring groove, offering reliable contamination protection and simplified axial location within the housing. Manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing provides a cost-effective solution for applications requiring consistent operation and high reliability.
6217-ZNR Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning | Benefit |
|---|---|---|
| 6217 | Standard designation for a single row deep groove ball bearing with 85mm bore, 150mm OD, and 28mm width. | Defines the core bearing dimensions and type. |
| Z | One side shielded. | Protects against contaminants from one side, retaining lubrication. |
| NR | Snap ring groove on the outer ring. | Facilitates secure axial positioning, simplifying housing design and assembly. |
6217-ZNR Bearing Structural Features & Performance Benefits
Optimized for Radial Loads: The single row deep groove raceway geometry is engineered to efficiently support high radial dynamic load ratings of 18,884 lbf, making it ideal for applications with significant radial forces.
Shielded Protection: The Z-shield helps retain the initial grease and excludes larger particulate contaminants, enhancing bearing service life in moderately dirty environments without the added friction of contact seals.
Simplified Assembly with Snap Ring: The outer ring snap ring groove (NR) allows for positive axial location, reducing the complexity and cost of the surrounding housing design. This feature is critical for maintaining precise bearing positioning.
Standard Precision & Clearance: Built to ABEC 1 | ISO P0 tolerance class with CN group radial internal clearance, this bearing ensures reliable, smooth operation for a wide range of industrial applications.
6217-ZNR Bearing Typical Application Areas
The 6217-ZNR is well-suited for a variety of industrial machinery and equipment, including:
- Electric Motors and Generators
- Industrial Gearboxes and Power Transmission Systems
- Material Handling Equipment (e.g., conveyor pulleys)
