| Code Segment | Technical Meaning |
|---|---|
| 6209 | Standard series designation for a single row deep groove ball bearing with a 45mm bore and 85mm outside diameter. |
| 2Z | Specifies shielded on both sides. This provides effective protection against the ingress of solid contaminants. |
| C4 | Indicates a greater than normal radial internal clearance. This is suitable for applications with significant temperature gradients or where interference fits are used. |
| VT269 | Manufacturer-specific suffix; consult technical datasheets for precise details. |
| R806 | Manufacturer-specific suffix; consult technical datasheets for precise details. |
Structural Features and Performance Benefits
- Robust Load Capacity: With a dynamic load rating of 7351 lbf and a static load rating of 4564 lbf, this bearing is built to handle significant radial forces, ensuring long service life.
- Optimized Internal Clearance: The C4 clearance provides operational stability in applications prone to thermal expansion, preventing preload and potential seizure.
- Contamination Resistance: The double-shielded (2Z) design effectively seals the bearing, protecting the chrome steel balls and raceways from dust and debris, enhancing reliability.
- High-Speed Capability: A limiting speed of 7,700 rpm is supported by the precision-ground components and the standard ABEC 1 (ISO P0) tolerance class.
- Durable Construction: Manufactured entirely from chrome steel for the rings, balls, and cage, this bearing offers high strength and resistance to wear.
