307/C3 Bearing Product Overview & Core Advantages
The 307/C3 deep groove ball bearing is a single row radial bearing engineered for robust performance in general industrial applications. This metric bearing features an open design and is manufactured to ABEC 1 | ISO P0 tolerance standards, ensuring reliable operation and interchangeability. Its key advantage lies in its optimized radial load capacity and C3 radial internal clearance, which makes it particularly suitable for applications where thermal expansion or fit-induced preload is a concern, providing stable performance across a wide temperature range from -30°C to 120°C.
307/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 307 | Standard bearing series designation indicating 35 mm bore diameter, 80 mm outside diameter, and 21 mm width |
| /C3 | Indicates greater radial internal clearance than normal (C0), suitable for applications with thermal gradients or interference fits |
307/C3 Bearing Structural Features & Performance Benefits
Deep Groove Geometry: The optimized raceway design enables the bearing to handle radial loads efficiently while accommodating moderate axial loads in both directions.
Chrome Steel Construction: All critical components including rings, balls, and cage are manufactured from chrome steel, providing excellent wear resistance and durability under the specified dynamic load rating of 7801 lbf and static load rating of 5957 lbf.
C3 Clearance Advantage: The increased radial internal clearance prevents binding in applications subject to thermal expansion, ensuring smooth operation and extended service life.
Open Design Flexibility: The open seal type allows for custom lubrication strategies and facilitates maintenance in various operating environments, supporting operation up to the limiting speed of 9,500 rpm.
