HTD TIMING BELT 3M-5M-8M-14M-20M

Curvilinear tooth profile.
•  Larger, more robust belt tooth than CT belts.
•  Higher load bearing capacity.
• ~ 30% more horsepower capacity than a comparable CT belt.
•  Improved distribution of stress in belt teeth.
•  Reduced tooth jump. •  Longer life. •  Efficiency up to 99%.

The tooth shape is the HTD profile according to ISO13050. 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 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.

Belt nomenclature

A belt is identified as follows:

a) the belt length or pitch length in millimetres, e.g. 1 400 mm;

b) the profile system,e.g. G","H", R",orS";

c] the pitch or tooth pitch in millimetres, e.g. 14 mm;

d) the width or belt width in millimeters, e.g.40 mm (for profile system S, the width in millimeters 10);

e) double-sided belts are designated by adding the letter D" before the designation of the profile system.


EXAMPLE  

A synchronous belt in the above profile systems of 1400 mm length, 14 mm pitch, and 40 mm wide is identified as follows:  

Profile system G  

1400-G14M-40  1400-DG14M-40
