If an XPZ belt with an effective length of 1837 mm is required for a drive, the ConCar V-belt XPZ 1837 Lw 10x8 mm is designed for precisely this combination. Its cross-section measures 10 × 8 mm. During operation, the belt runs in the flanks of the matching pulley groove and transmits the rotary motion from one shaft to the next. This allows it to be used in machines and assemblies that employ a compact, narrow V-belt drive. With an effective length of 1837 mm, this version falls within the middle range of available XPZ lengths.
The standardized XPZ profile includes the trapezoidal shape typical of narrow V-belts and a flank angle of approximately 40°. The belt thus fits into a matching XPZ pulley via its flanks. Therefore, when replacing a belt, not only the length but also the existing profile is crucial.
The belt features open flanks and molded teeth. A robust rubber compound forms the belt body, while the fiber-reinforced casing and integrated tensile cords provide the dimensional stability and tensile strength necessary for V-belts. The molded teeth on the inside improve flexibility and, with appropriately small pulley diameters, can reduce the bending stress on the belt. The 40° profile geometry is designed to fit suitable narrow V-belt pulleys.
Narrow V-belts with the XPZ profile are used, among other things, for fan and blower drives, pumps, compressors, conveyors, and machine assemblies. The 1837 mm version is the right choice if the existing drive is designed for precisely this effective length. For a reliable selection, the belt profile and pulley geometry should always be taken into account.
For a clean installation, the pulleys must be aligned and free of damage or heavy deposits. The XPZ belt should be installed without twisting and without mounting it over the pulley edge. The tension is then adjusted according to the drive configuration. For multi-drive systems, only belts specifically designed for that application and compatible with each other should be used.
For selection according to DIN 7753 / ISO 4184, the profile and effective length of the existing drive should be compared with the specifications of the new belt. The outer and inner lengths can serve as additional comparison values. The belt specified here has 1837 mm Lw, 1850 mm La, and 1799 mm Li.
A V-belt should be regularly inspected for visible cracks, frayed edges, unusual shiny spots, abrasion, or other signs of wear. Changes in tension or a distinct squeaking noise can also indicate a need for maintenance in the drive system. When replacing the belt, it is advisable to check the pulleys and the alignment of the entire drive.
When selecting a belt, you shouldn't just focus on the nominal length. The profile, effective length, and compatible pulleys are crucial. This particular belt has an outer length of 1850 mm and an inner length of 1799 mm. These values can be helpful in identifying an existing belt.
A ConCar narrow V-belt in the described version XPZ 1837 Lw with a 10 × 8 mm cross-section is supplied. Please compare the specifications with your existing belt and/or pulley before ordering to ensure the profile and length are compatible with your drive system.
