Molevion Zephyron HSB 5 High-Speed Bearing Oil

Zephyron HSB 5 is a low-viscosity, PTFE-enhanced synthetic oil for the highest-speed mechanisms in a drone — brushless motor bearings, FPV airframes and precision gimbal motors running above the range of a general-purpose oil.

Key benefits

• PTFE micro-particles form a low-friction boundary film that reduces start-up torque
• Low base viscosity minimises viscous drag and heat in high-RPM bearings (typically above 15,000 RPM)
• Maintains a thin, stable film across the temperature range of competitive FPV and gimbal use
• Compatible with ceramic-hybrid bearings used in high-RPM brushless motors

Application

High-speed brushless motor bearings, FPV and competition airframes, precision camera gimbal motors, and rotating assemblies operating outside the speed range covered by general-purpose drone oils.

Recommended platforms

Consumer · FPV & Racing · Cinematography · Light Show · University & Research

Material compatibility

Compatible with the metals and engineering plastics specified in drone bearing assemblies, including ceramic-hybrid bearings.
