SP Series Metric V-Belts -SPZ, SPA, SPB, SPC (Oil & Heat Resistant/Static Dissipating)
Built to ISO Standard 4184. SP series V-belts were the forerunners of the RMA deep wedge, high capacity V-belt sections. These deep-wedge belts (38°) allow for more power, high speed ratios, smaller center distances and more compact drives. They are replacement belts for many imported machines and for machinery built for export.
These V-belts also are factory matched which eliminates belt set matching. Non-standard lengths are available on special order. SP series Metric V-belts are specified by letters indicating the section and numbers giving the pitch length in millimeters - Example: SPZ512.
Although metric V-belts are generally designated by section and datum length, they are sometimes labeled with the section letters, belt length in millimeters and the letters "La" (approximate length), "Li" (inside length) or "Lw" (effective length). Care should be used here since all manufacturers do not use the same definitions.
