307SG Bearing Product Overview & Core Advantages
The 307SG is a single row deep groove ball bearing designed for high-performance industrial applications requiring reliable radial load support. Manufactured to ABEC 1 | ISO P0 precision standards, this bearing delivers consistent operation and long service life. Its open design allows for versatile lubrication options, while the CN radial internal clearance provides optimal performance under standard operating conditions. Constructed entirely from chrome steel, it offers excellent durability and resistance to wear, making it a robust solution for demanding environments.
307SG Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 307 | Standard bearing series designation indicating specific dimensions (35mm bore, 80mm OD, 21mm width) |
| SG | Indicates bearing is manufactured from chrome steel for both rings and components |
Note: This is an open bearing with no seals or shields, providing maximum flexibility for custom lubrication solutions.
