Bearing & motor thermal
High-temperature greases (rated to 150 °C+) and VPI/trickle impregnation resins that lock windings, reduce inter-turn thermal resistance, and maintain bearing lubrication over 60,000+ operating hours.

SOLUTIONS · FANS
Cooler, quieter, longer-lived fan systems.
Fan motor cooling and bearing thermal management, lubrication, impregnation, and interface materials that extend the life of moving thermal hardware.
The Challenge
The cooler needs cooling too.
A server fan spinning at 15,000 RPM dissipates 3–8 W from its motor winding alone, while bearing temperatures can reach 80–120 °C in confined chassis. Over tens of thousands of hours, heat degrades lubricant viscosity, increases acoustic noise, and accelerates winding insulation breakdown. When a fan fails early, the equipment it was protecting can cascade into thermal shutdown, making fan reliability a system-level concern, not just a component issue.
HeTone supplies bearing greases rated for continuous duty above 100 °C, winding impregnation resins that improve thermal conductivity by up to 30 %, and board-level interface materials for driver electronics, from Henkel, Loctite, and specialty lubricant partners. We match the material set to your fan motor class and duty profile.
Key Applications
Where these materials work.
Server and data-centre rack fans (40–80 mm)
Telecom cabinet and base-station fans
HVAC blower and centrifugal fan assemblies
Automotive cooling fan modules (radiator, condenser)
Industrial ventilation and process-cooling fans
What We Provide
A qualified material set, not a catalogue.
Licensed materials, the components around them, and the engineering to sign the system off.
Driver-board interface
Thermally conductive gap fillers (1.5–3.0 W/m·K) and adhesives that move heat from fan-driver ICs into the motor housing, maintaining stable PWM speed control without derating at high ambient temperatures.
Lifetime engineering
Material selection aligned to the temperature class (B/F/H), speed range, and L10 bearing-life targets your fan platform must certify against, with accelerated ageing data to support your reliability claims.
