Description
The Gates CX90 is a heavy-duty Type CX Gripnotch cogged V-belt engineered for demanding HVAC and industrial power transmission applications. With a 94.2-inch outside diameter, this belt is designed to deliver reliable, efficient performance across a wide range of blower, fan, and drive systems commonly found in commercial and residential HVAC equipment.
Gripnotch Cogged Design
The CX series features Gates’ signature Gripnotch notched construction, which reduces bending resistance and heat buildup compared to standard classical V-belts. The cogged profile allows the belt to flex more easily around smaller sheaves, improving grip, reducing slippage, and extending service life — even under high-load, continuous-duty conditions.
