| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| 307 | Standard bore diameter series | 35mm bore diameter for standard shaft fits |
| M | Brass cage construction | Enhanced stability at limiting speed: 9,500 rpm |
| FF | Machined brass cage with special design | Optimized for high-speed applications and smooth operation |
307MFF Bearing Structural Features & Performance Benefits
Deep Groove Geometry: The optimized raceway design enables excellent radial load capacity with dynamic load rating of 7,801 lbf and static load rating of 5,957 lbf, making it suitable for moderate to heavy radial loading conditions.
Precision Machined Brass Cage: The M-FF cage design provides superior guidance and stability at high rotational speeds, contributing to the bearing's exceptional limiting speed of 9,500 rpm while maintaining precise ball positioning.
Tight Dimensional Tolerances: With bore diameter tolerance of -0.012mm to 0 and outside diameter tolerance of -0.013mm to 0, this bearing ensures precise fit and consistent performance in precision applications.
Open Design Advantage: The unsealed construction allows for custom lubrication strategies and facilitates easy inspection and maintenance, while the chrome steel components provide excellent corrosion resistance and mechanical strength.
