Description
OPTIBELT 5M 120 (HTD) belongs to timing belt, part of our Power transmission range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for 5M 120 (HTD) and any equivalents.
This Optibelt Omega timing belt uses the HTD 5M profile with a 120 mm length and 5 mm pitch. It is a synchronous belt for drives where the belt teeth mesh with pulley grooves to keep motion in step. Use the marking and measurements to confirm it matches your drive before ordering.
HTD profile timing belts are common on compact drives that need positive synchronization rather than friction. The rounded tooth form of the HTD 5M profile suits small pulleys and light-duty indexing, positioning or transmission tasks. Confirm the belt by reading the back marking and checking that the profile and length match the original belt.
To verify fit, compare the profile and the 120 mm length against the belt you are replacing. Check the pulley grooves for wear and make sure the belt sits correctly in the grooves without riding high. If the drive uses more than one belt, replace the full set at the same time so the load stays even.
When you request a quote, send the part number 5M 120 (HTD) and the belt marking. If you are unsure of the correct belt, include the profile and length from the old belt and the pulley details. The team can confirm the belt or suggest an equivalent.
