⚙️Product Description:
The F3-6 (3x6x2.8mm) is an ultra-small miniature thrust ball bearing designed strictly for pure unidirectional axial loads in micro-precision systems. Featuring a 3mm bore, 6mm outer diameter, and a slim 2.8mm height, this 3-piece separable assembly consists of a shaft washer, a housing washer, and a ball retainer. To meet diverse operating speeds and temperatures, we offer both stamped steel cages and wear-resistant brass cages. Supplied under our trusted RMO brand, we also provide global OEM manufacturing and sourcing for medical device makers, RC hobby brands, and optical instrument developers.
⚙️Product Features:
- 3-Piece Separable Design: Easily removable shaft washer, housing washer, and ball assembly streamline mounting and maintenance in micro-machinery.
- Steel & Brass Cage Options: Choose durable steel cages for cost-effective standard use, or solid brass cages for high-speed stability, lower noise, and heat dissipation.
- Pure Axial Thrust Performance: Specifically engineered to absorb axial forces acting along the shaft axis without radial deflection in tiny spaces.
- Precision Micro-Lapped Grooves: Mirror-ground ball raceways deliver ultra-low frictional torque and whisper-quiet operation at elevated RPMs.
⚙️Product Application:
Engineered for pure axial force positioning in micro-mechanisms, the F3-6 bearing is widely specified in:
- RC model aviation: RC helicopter swashplates, tail rotor pitch controls, and micro actuators.
- Medical equipment: precision micro-metering pumps, dental handpieces, and surgical tools.
- Precision optical & audio devices: camera lens focus mechanisms, micro turntables, and optical positioning stages.
- Miniature hardware: precision fishing reel drag assemblies, micro valves, and laboratory automation.
⚙️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. |
