The Optibelt 123 3M 15 is an HTD timing belt with an HTD 3M profile and a 123 mm length. The 3 mm pitch identifies the tooth spacing for this synchronous drive belt. Use the profile and length to confirm this belt matches your drive before requesting a quote.
The HTD 3M profile is a synchronous belt profile with a 3 mm pitch. The 123 mm length is the belt's datum length. Together, these two figures define the belt's fit on the pulleys and its path around the drive. A buyer matching a replacement should read the marking on the back of the old belt and compare the profile and length directly.
When you send a quote request, include the part number 123 3M 15 and the profile and length from your belt. If the marking is worn, measure the old belt and note the tooth profile and length. The team can confirm the belt or suggest an equivalent based on the data you provide.
