ConCar V-belt XPZ 1937 Lw 10x8 MM

Product overview

The ConCar XPZ 1937 Lw 10x8 mm V-belt is a form-toothed narrow V-belt for drives with an XPZ profile. It has an effective length of 1937 mm and a cross-section of 10 x 8 mm. Crucially, the belt profile, effective length, and pulleys must be a perfect match. When this is the case, the trapezoidal belt cross-section ensures a secure fit in the groove and reliable power transmission. With an effective length of 1937 mm, this belt falls within the middle range of available XPZ lengths.

The most important dimensions

• Belt profile: XPZ
• Effective length: 1937 mm
• External length: 1950 mm
• Internal length: 1899 mm
• Width × Height: 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

Structurally, this is a narrow V-belt with open flanks and molded teeth. The belt flanks transmit power in the pulley groove. Inside, high-strength tensile cords provide the necessary load-bearing capacity, while the molded teeth enhance flexibility during rotation. The standardized geometry according to DIN 7753 / ISO 4184 simplifies the selection of a suitable replacement belt.

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 1937 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

During installation, the belt should be placed on the pulleys without tension and not forced over them. Before installation, the pulleys, alignment, and groove profile must be checked. The belt tension must be set according to the specifications of the respective machine manufacturer. Excessive or insufficient tension can increase wear and impair the drive's function.

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 1937 mm Lw, 1950 mm La, and 1899 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

The correct profile size is crucial. An XPA-sized belt does not automatically replace an XPZ, XPB, or XPC belt. The effective length must also match the existing drive. For this article, XPZ and a length of 1937 mm are the relevant specifications.

Delivery

A ConCar narrow V-belt in the described version XPZ 1937 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.
