The Optibelt 8T 2.5/277 is a timing belt with a T2.5 profile and a 277 mm length. The 2.5 mm pitch identifies the tooth spacing, while the 277 mm length defines the belt's circumference. Use these two values to confirm the belt matches your drive before requesting a quote.
When reading the marking on the back of an old belt, the profile and length are the first items to verify. The T2.5 profile has a 2.5 mm pitch, and this belt is 277 mm long. If your drive uses a T2.5 pulley, the 277 mm length must match the original belt's path around the pulleys and any idler. A different length will change the center distance or require a different tension setting.
For a quote, send the part number 8T 2.5/277 and the quantity you need. If you are replacing a belt on a drive where the old marking is worn, measure the length along the belt's back and confirm the tooth profile. The profile and length are the critical dimensions for a direct fit. We carry Optibelt timing belts and can help you confirm the correct belt for your application.
Inspect the pulleys and tensioner at the same time. Worn pulley teeth or a weak tensioner can damage a new belt. If the drive uses multiple belts, replace them as a set to keep loads even. The T2.5 profile and 277 mm length are the key specifications for this Optibelt belt.
