13x10 (SPA) clad narrow profile V-belt
Description
Narrow profile clad V-belts with the same profile width have a higher profile height than classic V-belts. Due to the larger adhesive surface, they provide greater torque transmission and generally longer service life. Typically, they are black in color. The SPA V-belt is a pair of belts with increased profile height (10mm height). Due to discrimination, the nominal profile width for some manufacturers is 12.7mm rather than 13mm. For simplicity, we list a section width of 13mm for each strap.
The Size field displays the belt width, the nominal length of the belt in millimeters, and the nominal length in inches. The Description field displays the nominal length of the belt and its nominal external size. The typical size of the product is Lp (pitch swing), which is printed on a strap. (It can also be called Lw or Ld, but it means the same thing.) If you don't want to recalculate/design, change belt type and are looking for a narrow profile V-belt, pay attention only to the Lp size! If you want to replace a classic belt with a narrow profile strap, find the size of your old belt among the classic straps 13 and read the Ld size for the given strap from the table and choose a suitable narrow profile V-belt!
The SPA profile belt can be used for a pulley marked SPA. From a technical point of view, it is a reliable solution for belt drives.
