6216-ZNR/C3 Bearing Product Overview & Core Advantages
The 6216-ZNR/C3 is a single row deep groove ball bearing designed for robust performance in demanding industrial applications. This metric bearing features a shielded design and a snap ring groove on its outer ring, facilitating secure axial location within a housing. Its C3 radial internal clearance makes it particularly suitable for applications with elevated operational temperatures or where interference fits are used, ensuring consistent performance under thermal expansion. Engineered from chrome steel for both rings and balls, it delivers reliable radial load capacity and durability, making it an excellent choice for general machinery where high reliability is paramount.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6216 | Basic bearing designation indicating a single row deep groove ball bearing with an 80 mm bore and 140 mm outside diameter. |
| Z | Denotes a shielded bearing on one side, providing protection against contaminants while allowing high-speed operation. |
| NR | Indicates the presence of a snap ring groove on the outer ring, enabling simplified and secure axial location in the housing. |
| /C3 | Specifies a greater than normal radial internal clearance, ideal for applications with thermal expansion or heavy interference fits. |
6216-ZNR/C3 Bearing Structural Features & Performance Benefits
This bearing's design incorporates several key features that translate directly into operational benefits:
- Shielded Design (Z): The steel shield effectively excludes larger contaminants while minimizing friction, contributing to the bearing's limiting speed of 4,500 rpm and extending service life in dirty environments.
- Snap Ring Groove (NR): This feature simplifies assembly and provides a positive axial location, reducing the complexity and cost of the surrounding housing design.
- Optimized Internal Geometry: The deep groove raceway and high-quality chrome steel construction enable high radial dynamic load rating of 16,344 lbf, ensuring reliable performance under significant loads.
- C3 Radial Clearance: This clearance group accommodates thermal expansion and interference fits, preventing premature failure due to excessive preload and ensuring stable operation across its specified temperature range of -30°C to 120°C.
- Precision Manufacturing: Manufactured to ABEC 1 | ISO P0 tolerance class, it guarantees consistent dimensional accuracy and smooth running for a wide range of general-purpose applications.
