We occasionally receive requests to provide belt interchanges or recommend replacements for synchronous belts identified as 8YU. The 8YU drive system was originally developed by Unitta, a Japanese company in partnership with Gates, for use in the automotive industry. The system was later commercialized for industrial type usage and introduced to Asian industrial markets.
The 8YU system uses a unique belt tooth and sprocket groove form that is not interchangeable with other industrial synchronous belt drive systems. There are no standard belts, available from Gates or other manufacturers, that can be used in 8YU type sprockets. Replacement belts must be 8YU type, and can be obtained either from OEM equipment manufacturers or from Unitta directly.
