JFB / MPFZ Self-Lubricating Flanged Bronze Bushings
A detailed image of a JFB flanged graphite bronze bushing, also known as a shoulder bearing
The JFB (MPFZ) series offers a versatile, all-in-one solution for applications requiring both radial and axial support. These flanged sleeve bearings, also known as shoulder bushings, are constructed from a high-strength cast bronze base with solid graphite lubricant plugs embedded throughout the bearing surface. This design ensures continuous, maintenance-free self-lubrication for the entire life of the component.
The integral flange provides a simple and effective method for axial positioning and for carrying light thrust loads, making it an ideal choice for a wide variety of industrial and mechanical applications.
Key Advantages of JFB Flanged Bushings
- Combined Load Support: The single-piece design efficiently handles both radial loads on the sleeve and axial loads on the flange face.
- Maintenance-Free Operation: Solid graphite lubricant eliminates the need for oil or grease, reducing downtime and preventing system contamination.
- Compact & Space-Saving: The integral flange removes the need for external thrust washers, simplifying assembly and saving valuable space.
- Precise Installation: The flange acts as a positive stop during press-fit installation, ensuring accurate and repeatable positioning.
- Superior Durability: Cast bronze construction delivers high load capacity and excellent resistance to wear, shock, and corrosion.
