The Gates AA 78 is a double-V (hexagonal) belt from the Hi-Power Dubl-V series. It has an AA profile and a length of 2032 mm. This type of belt drives pulleys from both sides, so it suits drives that use reversing or multiple driven pulleys.
Double-V belts are used where a single belt must make contact with pulleys on both its top and bottom faces. That layout is common on drives with reversing rotation or with several driven pulleys from one belt path. The AA profile and 2032 mm length identify the belt's cross-section and outside length.
To confirm fit, read the marking on the back of the old belt and compare the profile and length to this page. Check the drive for pulley wear, misalignment and proper tension before installing a replacement. If the belt runs in a set, replace all belts in the set at the same time.
Send the part number, the belt marking and the drive details by WhatsApp or email. Our team replies promptly and can help confirm the right belt or suggest an equivalent.
