F627 2rs Bearing Product Overview & Core Advantages
The F627 2rs is a metric single row deep groove ball bearing designed for reliable performance in compact spaces. Its key advantage lies in its sealed construction (2RS) which provides robust protection against contamination while retaining lubrication. This bearing excels in handling radial loads with a dynamic load rating of 629 lbf and is engineered for smooth operation. The combination of chrome steel rings and balls with a stainless steel cage ensures durability and consistent performance, making it a dependable choice for applications requiring ABEC1 precision and moderate speed capabilities.
F627 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| F627 | Basic bearing designation indicating a specific size series (7mm bore, 22mm OD, 7mm width). | Defines the compact bearing dimensions for space-constrained designs. |
| 2RS | Contact rubber seals on both sides of the bearing. | Provides excellent sealed protection against dust and moisture, extending service life and reducing maintenance. |
