This Optibelt Alpha Flex timing belt is built for long, continuous drives where synchronous power transmission is required. With an HTD 5M profile, a 5 mm pitch and a 12000 mm length, it is suited to equipment layouts that need a single uninterrupted belt run.
The HTD 5M profile is a synchronous belt profile used in drives that require precise timing between pulleys. The 5 mm pitch and 12000 mm length make this belt appropriate for long-span applications where a standard length belt would require a splice or intermediate drive. It is a single belt, not a banded or double-V design.
To confirm fit, read the marking on the back of the existing belt. The part number should match 25 / 5M 12000 AFX. Check the belt profile against the pulley grooves: an HTD 5M belt must run on HTD 5M pulleys. Also verify the length by measuring the old belt or checking the drive documentation, since the 12000 mm length is specific to this part.
