HTD pulleys have a different design from the traditional toothed pulleys. The axial grooves are designed to allow the beltteeth to catch the pulley teeth with negligible triction. HTD Pulleys are available with full hub and for assembly with SER-SIT taper bushing.
SIT EXCELITE® ES - Narrow V-Belts are manufactured in accordance with ISO 4184 -and DIN 7753.
Our high performance narrow v-belts have been specially designed for heavy-duty applications to deliver up to 50% more power than classical v-belts. Can be used in a wide range of industrial and agricultural fields such as compressor, fans, pumps and the other heavy-duty equipment.
Here are the product dimension :
- Belt width : 10 mm
- High belt : 8 mm
- Inside length : refer to the last number in every product names, for example : CLSPZ487, so the inside length is 487 mm.

TOP DRIVE® HTD belt is an evolution of standard positive drive belts. The tooth shape is the HTD profile according to ISO 13050.
This profile has been used for many years in a wide range of applications and it is well known for its outstanding performances. Power transmission is much higher compared to the classic inch trapezodial profile.
The circular-arc tooth provides superior tooth jump resistance and provides a smooth tooth engagement. The noise level is remarkably reduced if compared to the classic trapezodial belts.
standard connecting links are used when roller chains are operated under normal conditions. for severe applications, press fit connecting links are suggested.
