Atlas Copco V-BELT XPA 1320 – 1092202991

1092202991 is the genuine XPA 1320 V-belt for the Atlas Copco G18-10 oil-injected screw compressor. XPA section — narrow wedge profile, 1320 mm effective length — single belt per drive assembly.

The G18’s V-belt drive handles full 18 kW motor output continuously. That load, combined with heat cycling from stop-start operation, degrades belt tension over time without visible cracking. A loose belt doesn’t just slip — it introduces torsional irregularity into the element, accelerating bearing wear upstream. Inspect every 2,000 hours; replace by 4,000 hours or at first sign of glazing. Genuine spec ensures the XPA cross-section and cord tension match the original pulley geometry exactly — aftermarket substitutes in this profile class vary enough in effective length to shift the drive ratio and void alignment.
