6216-2Z/C3WT Bearing Product Overview & Core Advantages
The 6216-2Z/C3WT is a single row deep groove ball bearing designed for robust performance in demanding industrial applications. This shielded bearing excels at handling primarily radial loads while also accommodating moderate axial loads in both directions. Its key advantages include a generous C3 radial internal clearance for stable operation under thermal expansion, and pre-lubrication for long-term, maintenance-free service. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers reliable precision and is ideal for applications requiring consistent performance and high reliability.
6216-2Z/C3WT Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6216 | Basic series designation; 80mm bore, 140mm OD, 26mm width | Defines standard bearing dimensions for interchangeability. |
| 2Z | Non-contact steel shields on both sides | Provides effective contamination protection while maintaining high-speed capability. |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion in applications with heavy loads or temperature fluctuations. |
| WT | Factory pre-lubricated with high-quality grease | Ensures immediate operation and long-term, maintenance-free performance. |
6216-2Z/C3WT Bearing Structural Features & Performance Benefits
- Optimized Single Row Design: The deep groove raceway and high-quality chrome steel construction provide excellent radial load capacity (16,344 lbf dynamic) and smooth operation.
- Superior Contamination Protection: The 2Z non-contact shields effectively retain lubricant and exclude larger particulate contaminants, significantly extending bearing service life without the speed penalty of contact seals.
- Stable Thermal Performance: The C3 internal clearance ensures operational stability and prevents preload under conditions of shaft or housing expansion, making it suitable for applications with variable operating temperatures.
- Ready-to-Install Convenience: The bearing is pre-lubricated and shielded, making it a maintenance-free solution that is ready for immediate installation, reducing assembly time and complexity.
6216-2Z/C3WT Bearing Typical Application Areas
