The Optibelt Omega 3M 420 is a timing belt with an HTD 3M profile, a 420 mm length and a 3 mm pitch. We carry it for maintenance, engineering and purchasing teams that need to match a belt already in service.
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 420 and the pitch reads 3 mm. If the old belt is worn or the marking is unreadable, measure the profile and length before ordering.
The part number 3M 420 combines the profile and the length. HTD 3M describes the tooth profile, while 420 gives the length in millimeters. The pitch is 3 mm. These three values are what you compare against the belt on the drive.
When you request a quote, send the full part number 3M 420 and the brand Optibelt Omega. If you are replacing a belt from another source, include the marking from the back of that belt so we can confirm the match against this Optibelt Omega timing belt.
