209-ZNR Bearing Product Overview & Core Advantages
The 209-ZNR is a single row deep groove ball bearing designed for robust performance in demanding applications. This metric bearing excels at handling primarily radial loads and features a snap ring groove on its outer ring for secure axial location within a housing. Manufactured to P0 tolerance class with standard radial internal clearance (CN), it offers reliable and cost-effective operation. Its shielded design and factory-applied grease lubrication provide effective contamination protection and long service life, making it an excellent choice for applications requiring high reliability and simplified assembly.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 209 | Standard bearing series designation, indicating a metric deep groove ball bearing with a 45mm bore, 85mm OD, and 19mm width. |
| Z | Signifies a non-contact shield on one side of the bearing, protecting against large contaminants while minimizing friction. |
| NR | Indicates the outer ring has a snap ring groove and is supplied with a fitted snap ring. This feature simplifies housing design and provides secure axial location. |
209-ZNR Bearing Structural Features & Performance Benefits
- Snap Ring Groove for Secure Location: The outer ring's integrated snap ring groove and supplied snap ring eliminate the need for complex housing shoulders or end caps, reducing assembly time and cost while ensuring precise axial positioning.
- Effective Contamination Protection: The shielded (Z) design effectively prevents larger particulate contaminants from entering the bearing, extending bearing service life and reliability in moderately dirty environments.
- Optimized Material Selection: Constructed from chrome steel rings and balls with a stainless steel cage, this bearing offers excellent durability and corrosion resistance for the cage, contributing to stable operation.
- Ready-to-Install Lubrication: Pre-lubricated with grease, the bearing is immediately ready for service, reducing maintenance requirements and ensuring smooth operation from startup across its specified temperature range of -30°C to 120°C.
209-ZNR Bearing Typical Application Areas
- Electric Motors and Gearboxes
- Industrial Fans and Blowers
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- Various Automotive Components
