217S Bearing Product Overview & Core Advantages
The 217S metric ball bearing is a high-performance single row deep groove ball bearing designed for reliable operation under radial loads. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers excellent precision and consistency for general industrial applications. Its open design allows for versatile lubrication options, while the chrome steel construction of all components ensures durability and a long service life across a wide temperature range from -30°C to 120°C.
217S Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 217 | Standard bearing series designation, indicating the boundary dimensions (85mm bore, 150mm OD, 28mm width). |
| S | Denotes a single row deep groove ball bearing construction. |
Key Specification Highlights: The bearing features an open seal type (no shields or seals) and comes with no pre-applied lubrication, providing maximum flexibility for the user to select the optimal lubricant for their specific application conditions.
217S Bearing Structural Features & Performance Benefits
- Robust Load Capacity: Engineered with a deep groove raceway, the 217S effectively handles significant radial dynamic load ratings of 21,762 lbf and radial static load ratings of 22,481 lbf, ensuring stable performance in demanding environments.
- Precision & Consistency: Built to ABEC 1 (ISO P0) tolerance class with a standard CN radial internal clearance, this bearing guarantees reliable, smooth, and low-vibration operation.
- High-Speed Capability: The combination of a precision-ground chrome steel cage and optimized geometry enables a high limiting speed of 4,800 rpm.
- Material Integrity: All critical components—rings, balls, and cage—are manufactured from high-grade chrome steel, providing excellent resistance to wear and fatigue.
- Flexible Lubrication: The open design allows for easy application of grease or oil, enabling users to tailor lubrication to specific speed, temperature, and life requirements.
