Optibelt RB ribbed belts are precision engineered for superior performance and manufactured for incredible durability. A wide range of custom manufactured constructions are available for automotive, serpentine, alternator power transmission applications and more.
Metric ribbed or Micro-V belt size listing information: Profiles listed below are US standard (J, L, M) and the lengths measured in inches. For the metric equivalent sizes (DIN ISO) reference the metric length and add a "P" to the profile (PJ, PL, PM). Example: J190 (US standard) is identical to a PJ483.
360 = 36.0 in. External Length J = Profile Section 6 = Number of Ribs
914 = 914 mm External Length PJ = Profile Section 6 = Number of Ribs
Note: The following section sizes (V-groove width) are the same in Standard/Metric Sizes: J/PJ, L/PL, M/PM. Profiles are the same, but lengths will be measured in either inches or millimeters.
OIL RESISTANT: Engineered rubber compounds and bonded fabric top layer gives added protection.
TEMPERATURE RESISTANCE: Increased capability to operate under conditions that make other belts brittle and crack, which saves costly replacement repairs.
LOW NOISE: Engineered rubber compounds and constructions make OPTIBELT ribbed belts some of the quietest and smoothest running belts available.
VERSATILE: Flex range that can accommodate difficult idler stresses and serpentine applications.
