The Optibelt HTD 3M 6 is a timing belt in the HTD series with an HTD 3M profile and a 1125 mm length. Its 3 mm pitch identifies the tooth spacing for drives built to that profile.
For a maintenance or purchasing professional, the profile and length are the two numbers that decide whether a belt will run correctly. HTD 3M sets the tooth geometry and the 3 mm pitch; 1125 mm sets the length around the drive. Both values are read directly from the belt data, so you can compare them with the marking on the belt you are replacing.
When you request a quote, send the part number 1125 3M 6 and confirm the profile and length from the old belt. If the marking is worn, a photo of the belt and the drive can help our team confirm the right belt or suggest an equivalent. We carry Optibelt belts and reply by WhatsApp or email.
This belt is a timing belt, also called a synchronous belt, and is not a V-belt, narrow V-belt, cogged belt, Poly-V, serpentine, double-V, banded, variable speed or CVT belt. Use the profile and length as the primary selection criteria and check the drive for worn pulleys or misalignment during replacement.
