ConCar V-belt XPZ 1312 Lw 10x8 MM

Product overview

For replacing a worn belt or equipping a new drive system, the ConCar V-belt XPZ 1312 Lw 10x8 mm is a suitable, defined XPZ design. It has an effective length of 1312 mm and a cross-section of 10 × 8 mm. This allows for precise identification of the required belt size based on the existing pulleys and belt dimensions. With an effective length of 1312 mm, this design is among the shorter belts in the available XPZ range.

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.

Structure and function

The belt has a trapezoidal cross-section with a flank angle of approximately 40° and a toothed underside. This design combines defined flank contact in the pulley with good flexibility. It is designed for use in suitable narrow V-belt pulleys and promotes uniform power transmission across the contact surfaces of the belt flanks.

Application examples

Narrow V-belts with the XPZ profile are used, among other things, for fan and blower drives, pumps, compressors, conveyors, and machine assemblies. The 1312 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.

Assembly and selection

When changing a belt, it is advisable to simultaneously check the condition of the pulleys and the tensioning device. The new belt must be fully seated in the groove. Correct tension and alignment help to prevent slippage, unnecessary heating, and premature wear.

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 1312 mm Lw, 1325 mm La, and 1274 mm Li.

Maintenance and replacement

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.
