Micro-V®

micro-vThrough its truncated rib design, Gates Micro-V® multiribbed belt ensures an outstanding performance at higher speeds on smaller diameter pulleys. This smooth-running belt provides a power capacity increase up to 80% higher than RMA standards. The Micro-V® size range has recently been extended and comprises more than 125 standard effective lengths covering a multitude of applications.

Identification

Durable yellow marking indicating type and dimension.

Construction

  • Truncated ribs ensure flexibility, reduce heat buildup and improve rib crack resistance.
  • High modulus, low stretch polyester tensile member provides superior resistance to fatigue and shock loads.
  • All elastomeric rubber compound provides oil and heat resistance.
  • Specially formulated fibre reinforced undercord stock improves beltstability.

 Advantages

  • Extremely smooth and cool running.
  • Very high power capacity per rib.
  • Long life due to extra load-carrying capacity.
  • Improved performance on back idlers.
  • Smaller drive package.
  • Tolerant of pulley groove debris.

Micro-V® belts are available in PJ, PL and PM cross-sections. The figure below shows a cross-sectional view illustrating the nominal belt dimensions — rib width and belt height. All these belts will operate in standard pulleys provided the pulleys are manufactured to the DIN 7867 or ISO 9982 standard for the specific cross-section.

bb = Nr x Sg
Where: Nr = number of ribs
Sg = pulley groove spacing
