HTB
®
Timing Belts
Oil, heat and abrasion-resistant.
The standard trapezoidal tooth timing belt design performs poorly
in high torque applications and high power drives at lower speeds.
To overcome this disadvantage the High Torque Belt (HTB) was developed using a
more efficient tooth profile.
Stock 5mm, 8mm and 14mm pitch HTB timing belts are listed below. Non-standard
lengths in these pitches are also available, as are belts with 3mm pitch.
HTB timing belts are specified by belt pitch length, tooth profile, and tooth pitch
code and belt width in millimeters. For example:
720 – 8M
– 30
