This Optibelt Omega belt is an HTD timing belt with a 3M profile, a 123 mm length and a 3 mm pitch. It is used where a compact synchronous drive needs a positive, non-slip connection between pulley and belt. Confirm fit by matching the profile, length and pitch to your drive.
HTD timing belts are common on small, precise drives such as positioning axes, light conveyors, pumps and compact machinery where the belt teeth mesh with a matching pulley groove. The 3M profile and 3 mm pitch identify the tooth form and spacing, while the 123 mm length sets the belt's path around the pulleys.
To confirm this belt suits your application, read the marking on the back of the old belt and compare profile, length and pitch with the data here. Check that the pulley grooves are clean and undamaged and that the drive is aligned. If you are replacing more than one belt on the same drive, order them together so the set is matched.
Send the part number 3M 123 (HTD) by WhatsApp or email for a quote. If you are unsure of the correct belt, include the old belt marking and details of the drive, and we can help confirm the right belt or suggest an equivalent.
