The Optibelt 3M 390 is an Omega timing belt with an HTD 3M profile, a 390 mm length and a 3 mm pitch. It fits drives that take an HTD 3M synchronous belt of this length. We carry this belt for maintenance, engineering and purchasing teams across the US, Canada, Mexico and South America.

The most reliable way to match this belt is to read the marking on the back of the belt you are replacing. Confirm the profile reads HTD 3M, the length reads 390 mm and the pitch reads 3 mm. If the old belt is worn or the marking is unreadable, measure the belt and count the teeth so the profile, length and pitch can be checked against the Optibelt 3M 390.

A timing belt that no longer carries its original marking can still be identified from the drive. Check the pulley grooves to confirm they are HTD 3M, then measure the belt length along its pitch line. The 3M 390 designation on this Optibelt Omega belt gives you the profile and the length in one reference, so the replacement can be selected without guessing.

Send the part number, the profile, the length and the pitch when you request a quote. If you are unsure whether the Optibelt 3M 390 is the correct belt for your drive, include a photo of the old belt and the pulley, and our team will help confirm the right belt or suggest an equivalent.
