Featuring integrated shields for contamination protection and a snap ring groove on the outer ring for simplified axial location, this bearing offers a compact, high-performance solution. Its optimized design ensures smooth operation across a wide temperature range, making it ideal for applications demanding high reliability and ease of installation.
6211-ZNR Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6211 | Standard bearing series designation indicating dimensions (55mm bore, 100mm OD) | Standardized bearing dimensions for interchangeability |
| Z | Shield on one side | Protects against contaminants while allowing higher speeds than contact seals |
| NR | Snap ring groove on outer ring | Enables secure axial positioning, simplifying housing design and assembly |
6211-ZNR Bearing Structural Features & Performance Benefits
Robust Construction: Manufactured from chrome steel rings and balls with a stainless steel cage, this bearing delivers excellent durability and corrosion resistance. The deep groove raceway geometry is optimized for handling significant radial loads.
Enhanced Sealing & Lubrication: The non-contact shield (Z-type) effectively retains the factory-applied grease lubrication and excludes larger particulate contaminants, contributing to a long service life and maintenance-free operation under normal conditions.
Simplified Mounting: The presence of the snap ring groove eliminates the need for complex housing shoulders or end caps, reducing assembly time and cost while ensuring precise axial location.
Performance Specifications: With a dynamic load rating of 10,386 lbf and a limiting speed of 9,000 rpm, the 6211-ZNR is capable of high-performance operation in demanding environments.
6211-ZNR Bearing Typical Application Areas
The 6211-ZNR is widely used in industrial machinery and equipment where reliable radial load support and straightforward installation are paramount. Common applications include:
- Electric Motors and Gearboxes
- Industrial Pumps and Fans
- Material Handling Conveyors
- Agricultural Machinery
- Automotive Components (e.g., alternators, idlers)
