17x14 (SPB) 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 SPB V-belt is a pair of B belt with increased profile height (14mm height). Due to this distinction, some manufacturers have a nominal profile width of 16.3mm instead of 17. For simplicity, we indicate a profile width of 17mm 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 17 and read the Ld size for the given strap from the table and choose a suitable narrow profile V-belt.
The SPB profile belt can be used for a pulley marked SPB. From a technical point of view, it is a strong solution for belt drives.
