⚙️Product Description:
The MF126ZZ (6x12x4mm) is a precision miniature flanged deep groove ball bearing engineered with an integrated outer ring flange (13.6mm OD). Specially designed for 6mm shafts in micro-mechanisms, the solid flange acts as a built-in axial stop, allowing the bearing to sit flush against housing walls without complex internal shoulders or retaining rings. Protected by dual steel dust shields (MF126ZZ) or optional contact rubber seals (MF126-2RS), it delivers exceptionally smooth rotation and ultra-low frictional torque in lightweight assemblies. We supply these high-precision miniature flanged bearings under our proprietary RMO brand, supported by flexible OEM manufacturing for global 3D printing, RC hobby, and precision instrument builders.
⚙️Product Features:
- Flush Mounting Flange Design: The integrated 13.6mm outer flange simplifies micro-housing machining and guarantees rock-solid axial positioning under thrust loads.
- Compact 6mm Bore Footprint: Perfectly matches standard 6mm precision rods, miniature lead screws, and small motor spindles without adding bulk.
- Low-Frictional Torque: Micro-lapped raceways and high-grade GCr15 chrome steel balls deliver high rotational accuracy and whisper-quiet operation at elevated speeds.
- Zero-Maintenance Dual Shielding: Metal ZZ shields effectively block airborne dust and particulate debris while retaining factory pre-filled synthetic grease.
⚙️Product Application:
Engineered for positive axial alignment and low friction in micro-drives, the MF126ZZ bearing is widely specified in:
- 3D printing & CNC hardware: filament extruders, lead screw top support mounts, and belt idler pulleys.
- RC hobby & robotics: RC car wheel hubs, transmission gear shafts, and camera gimbal linkage arms.
- Office & optical devices: laser barcode scanners, label printers, and automated paper feeding rollers.
- Medical & micro-drives: micro peristaltic pumps, optical rotary encoders, and miniature stepper motors.
⚙️Precautions:
| 1. Keep clean | 2. Use with caution | 3. appropriate tool | 4. Hot-loading | 5. Be careful of rust |
| Dust will have a bad effect on the bearing, so keep the surrounding clean. | Strong impact during use can easily cause scratches and indentations. | Avoid replacing existing tools, and use appropriate tools. | Bearings are precision parts, so hot installation is recommended. | Sweat on your hands during operation will cause rust, so it is best to wear gloves. |
