6217-2Z/C3WT Bearing Product Overview & Core Advantages
The 6217-2Z/C3WT is a single row deep groove ball bearing designed for exceptional performance in demanding industrial applications. This precision bearing features integral shielded protection and is characterized by its C3 radial internal clearance, making it ideally suited for applications with thermal expansion or where interference fits are used. Its robust construction from chrome steel ensures high durability and reliable operation under significant radial loads, offering a compact and efficient solution for a wide range of machinery.
6217-2Z/C3WT Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Interpretation | Technical Significance |
|---|---|---|
| 6217 | Basic Bearing Number | Denotes a single row deep groove ball bearing with an 85 mm bore, 150 mm OD, and 28 mm width. |
| -2Z | Shielded on Both Sides | Provides effective protection against contamination from solid particles while allowing for higher limiting speeds compared to contact seals. |
| /C3 | Radial Internal Clearance | Indicates a greater than normal clearance, beneficial for applications with elevated operational temperatures or tight shaft/housing fits. |
| WT | Lubrication | Specifies that the bearing is supplied without lubrication, allowing the user to apply a grease or oil suitable for the specific application. |
6217-2Z/C3WT Bearing Structural Features & Performance Benefits
- High Load Capacity & Rigidity: The deep groove raceway and chrome steel construction enable the bearing to support high radial dynamic load ratings of 18,884 lbf, providing stable and rigid support for rotating shafts.
- Optimized for Contaminated Environments: The non-contact steel shields (2Z) on both sides effectively retain lubricant and exclude larger contaminants, extending bearing service life without the drag associated with contact seals.
- Versatile Internal Clearance: The C3 clearance accommodates thermal expansion in high-temperature applications or dimensional changes from press fits, preventing preload and potential seizure, thus ensuring reliable performance.
- Broad Operating Range: With a temperature range from -30°C to 120°C and compliance with ROHS and REACH, this bearing is suitable for diverse industrial environments and adheres to stringent environmental standards.
