Built on Quality. Driven by Technology.
One Core Gene. Three Dedicated Fields.
Same EPDM/HNBR DNA. Same high-pressure vulcanization mastery. Engineered for extreme torque, heat, and shock loads.



Forging Zero-Compromise Drives for High-Torque Harvest Operations.
Engineered to conquer the four greatest agricultural hazards: violent shock loads, heavy dust/debris, extreme flexing heat, and mid-harvest downtime.
High-tensile aramid/polyester tensile cords withstand sudden torque spikes during heavy crop intake without snapping or elongation.
Precision sidewall angle and anti-wear fabric cover deliver flawless CVT ratio changes under variable loads.
Raw-edge cogged or wrapped EPDM construction resists abrasion from straw, grit, mud, and ambient oil.
Built for peak harvesting seasons where continuous multi-day operation demands absolute dependability.
Pour Every Horsepower Onto the Asphalt and Trail Without Loss.
Engineered for scooters, high-cc motorcycles, ATVs, and UTVs. HEIYI CVT belts eliminate power loss, delivering instant acceleration and whisper-quiet operation under severe dynamic loads.
Engineered for Harsh Industrial Plant & Vehicle Systems.
From 24/7 factory conveyor lines to extreme under-hood engine temperatures (-40°C to 120°C), our classical V-belts, ribbed belts, and timing belts deliver optimal friction grip and long service intervals.

Every Millimeter of Precision Is Forged Through Three Hardcore Processes.
From molecular compounding to torture testing — see where uncompromising transmission quality is born.
The Formula
Molecular-grade EPDM/HNBR precision compounding. Heat resistance, oil resistance, and crack resistance are engineered at the raw material level.
The Skeleton
High-tenacity Kevlar® / polyester cords and rubber matrix are fused under extreme heat and pressure. Monolithic vulcanization eliminates delamination under heavy shock loads.
The Torture Test
Millions of flex cycles, shock torque loads, high-temperature CVT chamber testing, and salt-spray corrosion. Every belt exceeds national and international OEM standards.
