Belt type S8M Supertorque timing belts
8mm pitch · Supertorque (STD) teeth · Metric sizes
S8M belts use the Supertorque (STD) tooth, a modified round tooth that carries more torque, runs more quietly and positions more accurately than a standard HTD belt of the same pitch. You’ll find them on industrial machinery, machine tools, pumps and conveyors. Search by the code on the old belt, such as S8M-1200-30, and use the filters to narrow it down by length or width.

Finding the right S8M belt
Reading the codeS8M-1200-30 is a S8M belt with a 1200mm pitch length and a 30mm width. The S at the front tells you it’s the Supertorque profile.
Counting teethPitch length divided by 8mm gives the tooth count, so a 1200mm S8M belt has 150 teeth.
Supertorque or HTD?An S8M belt has the same 8mm pitch as an 8M HTD belt, but the teeth are shaped differently and need S-profile pulleys. Replace like for like; if the old belt has no S in the code, it’s probably HTD.
Tip: For serpentine drives, see DS8M double-sided belts. belts cut to width or length to order can’t be returned unless faulty, so check the pitch, length and width before ordering.
