The Optibelt Omega 3M 252 is a timing belt with an HTD 3M profile, a 252 mm length and a 3 mm pitch. To match it to the belt you are replacing, compare the marking on the back of the old belt with these three values.

Start with the profile. HTD 3M identifies the tooth shape and pitch of the belt, and it must match the pulleys on the drive. A belt with a different profile will not seat correctly in the grooves, even if the length looks close. The 3 mm pitch is the distance from one tooth to the next, so it is part of what defines the profile.

Then check the length. This belt is 252 mm, measured as the datum length for the HTD 3M profile. If the old belt is worn or stretched, its printed length is still the reference to use. Read the full part number from the back of the belt, including the brand and series, and send it to us if you want us to confirm the match.

Finally, look at the drive itself. Check the pulleys for worn teeth, the flanges for damage and the belt for uneven wear or cracking. If the drive uses more than one belt, replace them as a set so the load stays shared. When you request a quote, send the part number, the profile and the length, and we will confirm the Optibelt Omega 3M 252 or suggest an equivalent.
