ConCar V-belt XPZ 3550 Lw 10x8 MM

Product overview

The ConCar XPZ 3550 Lw 10x8 mm V-belt is designed for power transmission in a suitable narrow V-belt drive. With its XPZ profile, an effective length of 3550 mm, and a cross-section of 10 × 8 mm, it fits drives that specify this exact belt size. Power is transmitted via the belt's flanks in the corresponding pulley groove. This makes the belt suitable both as a replacement part for an existing machine and for equipping a newly built drive. With an effective length of 3550 mm, this version is among the longer XPZ variants in the available range.

Technical dimensions

• XPZ profile
• 3550 mm effective length Lw
• 3563 mm external length La
• 3512 mm internal length Li
• 10 × 8 mm cross-section

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 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.

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

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 3550 mm Lw, 3563 mm La, and 3512 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

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 3563 mm and an inner length of 3512 mm. These values ​​can be helpful in identifying an existing belt.

Delivery

A ConCar narrow V-belt in the described version XPZ 3550 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.
