SIT 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 trapezoidal profile.
The circular-arc tooth profile provides superior tooth jump resistance and provides a smooth tooth engagement. The noise level is remarkably reduced if compared to the classic trapezoidal belts. For each pitch a wide range of lengths and widths is available.
