They are used in small structures requiring axial positioning, guiding or limited mounting movement.
Flanged Bearing Supplier
F686 and MF74 miniature flanged deep groove ball bearings are used for axial positioning, guiding and compact transmission structures.

Product Overview
Flanged bearings have a flange on the outer ring for axial positioning and easier mounting. F686 is a metric flanged series model, while MF74 is a smaller miniature flanged bearing for compact mechanisms.
Selection should confirm flange outside diameter, flange thickness, bearing width, sealing suffix and material version, not only bore and outside diameter.
Specifications
| Model | Size | Material | Sealing | Applications |
|---|---|---|---|---|
| F686 | 6x13x3.5mm; flange OD approx. 15mm, flange thickness approx. 0.8mm | GCr15 bearing steel / stainless steel | ZZ or 2RS, to be specified | Power tools, drones, model aircraft, fitness equipment, e-scooters, office equipment |
| MF74 | 4x7x2.5mm; flange OD approx. 9mm, flange thickness approx. 0.6mm | GCr15 bearing steel / stainless steel | ZZ or open, to be specified | Micro motors, model car axles, precision instruments, 3D printers, medical micro pumps |
Selection Notes
- Flange outside diameter and flange thickness are key parameters.
- Use ZZ or 2RS when dust protection or sealing is required.
- Confirm shielded width and suffix for miniature flanged bearings.
- Provide drawings, samples or mounting space dimensions before ordering.
FAQ
Both are flanged bearings, but their sizes and application spaces are different. MF74 is for smaller miniature mechanisms.
Stainless steel versions can be confirmed according to model, quantity and material requirement.
