Product Details

The Caliso 445K5 is a K-section Poly-V (Multi-Rib) Serpentine Belt designed for reliable power transmission in a wide range of industrial and automotive applications.

  • Number of Ribs: 5
  • Outside Circumference (OC): 45.25 in (1,149 mm)
  • Pitch Length: 44.5 in (1,130 mm)
  • Top Width: 0.70 in (17.80 mm)
  • Belt Depth: 0.17 in (4.3 mm)

Poly-V belts use triangular-section longitudinal ribs that allow the belt to flex over small-diameter pulleys while achieving higher peripheral speeds than traditional V-belts. The compact, low-profile design makes the 445K5 well-suited for space-constrained drive systems requiring efficient torque transfer.
