V-belt, reinforced SPZ profile, Width (outer part) 9.5 – 9.7 mm, Height 8 mm, many lengths: from 512 mm to 3550 mm.
V-belt profile SPZ refers to a narrow-profile type of V-belt. Unlike a classic belt, a narrow-profile belt has a much greater section depth, a narrower wedge shape, and a shorter length. Narrow profile V-belts are used where increased demands are placed on energy distribution and smooth operation.
Narrow-profile V-belts are used where it is necessary to implement a compact transmission, while it is important to maintain high speed and high power. The use of a narrow-profile V-belt makes it possible to halve the number of grooves on the pulley, as well as the overall number of belts in the transmission. Recently, most power plants have begun to be equipped with universal pulleys, so it has become possible to use narrow-section V-belts instead of standard ones, as was the case before. This approach will allow you to obtain more transmission power, as well as extend the service life of the V-belt itself.
Depending on the type, V-belts have a convergence angle of the sides of 26°, 32°, 34°, 40° with tolerances established for them up or down.
