Belt type 14M HTD timing belts & RPP14

14mm pitch · Round HTD teeth · Metric sizes

14M timing belts are HTD (High Torque Drive) belts with a 14mm pitch and rounded teeth, which carry more load and run more quietly than the older trapezoidal designs. RPP14 is Megadyne’s parabolic-tooth version and runs in the same pulleys. You’ll find 14M belts on heavy industrial drives, mining, paper mills and large process machinery. Search by the code on the old belt, such as 14M-1400-55, and use the filters to narrow it down by length or width.

Finding the right 14M belt

Reading the code14M-1400-55 is a 14M belt with a 1400mm pitch length and a 55mm width. Some brands write it the other way round, such as 1400-14M-55 or 55-14M-1400, but the numbers mean the same thing.

Counting teethPitch length divided by 14mm gives the tooth count, so a 1400mm 14M belt has 100 teeth. If the code has worn off, count the teeth and multiply by 14 for the length.

HTD or Supertorque?Supertorque S14M belts have the same 14mm pitch but a different tooth shape. They need their own pulleys, so check the tooth profile before swapping.

Tip: For the drive, we stock matching 14M timing pulleys and metric taper lock bushes. For serpentine drives, see D14M double-sided belts. Note: belts cut to width or length to order can’t be returned unless faulty, so check the pitch, length and width before ordering.
