Not sure if this will help as it's not the same Gates partnumber (8M-250T-12CTS Blue vs 8MGT-2000-12). Both are Gates products. It does meet the 8mm pitch, 250 teeth, 12mm wide, 2000mm length requirement though. Wonder if the performance specs are the same? The 8M is oil and heat resistant. Industrial application I guess.
