217-Z Bearing Product Overview & Core Advantages
The 217-Z is a single row deep groove ball bearing designed for exceptional performance in demanding industrial applications. Engineered with precision tolerances and a shielded design, it offers reliable operation under significant radial loads. Its construction from high-grade chrome steel ensures durability and long service life, making it an ideal choice for applications requiring high reliability and consistent performance. The bearing is pre-lubricated with grease, facilitating easy installation and immediate operation.
217-Z Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Interpretation | Technical Significance |
|---|---|---|
| 217 | Basic Bearing Number | Defines the standard boundary dimensions: 85mm bore, 150mm OD, 28mm width. |
| -Z | Shield Designation | Indicates the bearing is equipped with a non-contact steel shield on one side, offering protection against contaminants while maintaining high-speed capability. |
217-Z Bearing Structural Features & Performance Benefits
- Robust Load Capacity: With a dynamic load rating of 21,762 lbf and a static load rating of 22,481 lbf, this bearing is built to handle substantial radial loads in continuous operation.
- Optimized High-Speed Performance: The combination of a lightweight nylon cage and precision-ground components allows for a high limiting speed of 4,800 rpm, reducing centrifugal forces and heat generation.
- Enhanced Contamination Resistance: The shielded seal (Z) effectively prevents the ingress of solid contaminants, extending bearing life and reducing maintenance needs in dirty environments.
- Precision and Stability: Manufactured to P0 tolerance class and standard CN radial internal clearance, it ensures smooth, low-vibration, and precise running, which is critical for many industrial machinery applications.
- Wide Operating Range: The standard grease lubrication and chrome steel construction provide a broad temperature range from -30°C to 120°C.
217-Z Bearing Typical Application Areas
The 217-Z deep groove ball bearing is versatile and finds use in a wide array of industrial sectors, including:
- Electric Motors and Generators
- Industrial Gearboxes and Transmissions
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- Pumps and Fans
