307SF Bearing Product Overview & Core Advantages
The 307SF is a single row deep groove ball bearing engineered for high-performance radial load applications. Characterized by its open design and manufactured to ABEC 1 | ISO P0 precision class, this bearing offers a robust and cost-effective solution for a wide range of industrial machinery. Its high radial dynamic load rating of 7801 lbf ensures reliable operation under demanding conditions, while the standard CN radial internal clearance provides optimal performance for most general applications. Constructed entirely from chrome steel, the 307SF delivers excellent durability and a long service life.
Model Code Breakdown
| Code Segment | Interpretation |
|---|---|
| 307 | Standard bearing series designation, defining the core dimensions: 35mm bore, 80mm OD, 21mm width. |
| S | Indicates a snap ring groove on the outer ring, enabling secure axial location within a housing. |
| F | Signifies a snap ring is supplied with the bearing, simplifying installation and inventory. |
| No Seal Suffix | The open (unsealed) construction allows for higher limiting speeds (9,500 rpm) and is suitable for applications where external lubrication is provided. |
307SF Bearing Structural Features & Performance Benefits
- Deep Groove Raceway & High-Capacity Design: The geometry of the deep groove raceways enables the 307SF to handle not only significant radial loads but also moderate axial loads in both directions, making it an exceptionally versatile ball bearing.
- Snap Ring Groove for Secure Mounting: The integrated snap ring groove and supplied ring provide a simple and effective method for axial location, reducing the complexity and cost of the housing design.
- Optimized for High-Speed Operation: The open design minimizes friction and heat generation, supporting a high limiting speed of 9,500 rpm. The one-piece chrome steel cage ensures reliable guidance of the balls at high rotational velocities.
- Precision & Reliability: Manufactured to ABEC 1 precision standards, this bearing offers consistent running accuracy and low noise levels, contributing to the smooth operation of the entire assembly.
307SF Bearing Typical Application Areas
