Synchronous Belts, commonly known as Timing Belts are a relatively new thing in the world of industrial belts. Created in 1954 Timing Belts are made with a much higher degree of precision than V-Belts. The Timing Belts are basically known as Toothed Belts. The advantages of Timing Belts are a lower cost, less noise, and reduced friction losses. On the other hand, the disadvantage is that like any other belt this one also wears over time and requires a replacement. Timing Belts can deal with up to 600 HP. Timing belts come in three main types: H-Type (HTD), S-Type (STPD), and Classical. HVH industrial is a supplier of timing or synchronous belts, so you can check the catalog of timing belts and find the right belt for you.
The H-type Timing Belts, commonly known as HTD, have a round tooth profile. There are single-sided and double-sided HTDs. The H-Type Timing Belts are available in 3mm, 5mm, 8mm, 14mm, and 20mm pitches.
The S-Type belts are commonly known as STPD The tooth gear design is circular. These belts are mainly used in Europe and Asia. There are single-sided and double-sided STPDs. S-Type Timing Belts are available in 3mm, 4.5mm, 5mm, 8mm, and 14mm pitches.
There are single-sided and double-sided Classical Timing Belts. They consist of four components: Cable Tension Member, Polychloroprene Backing, Polychloroprene Teeth, and Nylon Facing. Classical Series Timing Belts are manufactured in 5 pitch sizes, XL, L, H, XH, and XXH.
