V-BELTS
UniMatch® 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 have the UniMatch® feature. This eliminates belt set matching with its multiple stocking problems.
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
.
NOTE:
Belt sizes up to 2240mm in length are also available in raw edge cogged construction. These belts are
designated by an "X" prefix rather than an "S" -
Example: XPB1400
. For Raw Edge Cogged Construction, add 25%
to the list price.
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.
