The Optibelt 3MHP 312 is a timing belt in the Omega HP series. Its profile is HTD 3M, and it measures 312 mm in length with a 3 mm pitch. Use these three values to confirm the belt matches your drive before you request a quote.
The profile and length are the first check when replacing a timing belt. HTD 3M describes the tooth geometry, and 312 mm gives the outside length. The 3 mm pitch is the distance from one tooth center to the next. If your old belt is marked with these values, the 3MHP 312 is the correct size to specify.
When you send a quote request, include the part number 3MHP 312 and the belt marking from your drive. If the old belt is worn or the marking is unreadable, measure the length and count the teeth to confirm the profile and pitch. Our team can help you match the belt to the pulley grooves and confirm the replacement.
Timing belts are often replaced as part of a drive service. Inspect the pulleys for wear or debris, check the tensioner, and replace the belt before it fails. The Optibelt 3MHP 312 is a direct replacement for drives that use an HTD 3M profile, 312 mm length, and 3 mm pitch.
