F608 2rs Bearing Product Overview & Core Advantages
The F608 2rs is a metric single row deep groove ball bearing designed for reliable performance in compact applications. Its sealed construction with nitrile rubber contact seals (2RS) provides effective protection against contaminants, making it suitable for environments where long service life and minimal maintenance are critical. This bearing is engineered to handle primarily radial loads and is characterized by its high limiting speed and stable operation within a wide temperature range.
F608 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| F608 | Basic bearing designation indicating a metric, single row deep groove ball bearing with an 8mm bore, 22mm OD, and 7mm width. |
| 2RS | Bearing is equipped with two (2) Nitrile Rubber (RS) contact seals on both sides, providing superior protection against dust and moisture ingress. |
F608 2rs Bearing Structural Features & Performance Benefits
- Robust Sealing: The dual nitrile rubber contact seals (2RS) effectively retain lubricant and exclude contaminants, enhancing bearing life in demanding conditions.
- High-Speed Capability: The stainless steel cage and optimized internal geometry contribute to a high limiting speed of 34,000 rpm, making it suitable for high-speed applications.
- Precision & Stability: Manufactured to ABEC1 tolerance class with a controlled MC3 radial internal clearance, ensuring smooth and consistent operation.
- Durable Construction: Components made from chrome steel (rings and balls) offer high wear resistance and load capacity, supporting a dynamic load rating of 630 lbf.
