ConCar V-belt XPZ 737 Lw 10x8 MM

Product overview

The ConCar V-belt XPZ 737 Lw 10x8 mm combines a defined belt size with the standardized XPZ narrow wedge profile. It has an effective length Lw of 737 mm and a cross-sectional area of ​​10 × 8 mm. This makes it a suitable replacement or installation option for machines whose pulleys are designed for this profile. The toothed design enhances the belt's flexibility as it rotates over the pulleys. With an effective length of 737 mm, this version is among the shorter belts in the available XPZ range.

• Cross-section: 10 × 8 mm

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.

Use in drive systems

Belt drives of this type are particularly common on fans, blowers, pumps, compressors, and conveyor systems. Narrow V-belts are also found in general mechanical engineering and agricultural machinery. Whether a specific belt is suitable for a machine always depends on its profile, effective length, pulley diameter, and drive power.

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 737 mm Lw, 750 mm La, and 699 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.

Frequently Asked Questions

A suitable replacement belt is selected based on its profile and the required effective length. For this product, these are XPZ and 737 mm Lw. The specifications of 750 mm outer length and 699 mm inner length help to match it to an existing belt size.

Delivery

A ConCar narrow V-belt in the described version XPZ 737 Lw with a 10 × 8 mm cross-section will be 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.
