AVX13 2018 LA TM TRUCK POWER MARATHON 2

The Optibelt MARATHON is developed for driving ancillary components in car and light commercial vehicle engines. Its construction uses a raw-edge, moulded-cog design that supports low heat build-up, stable belt tension, and consistent power transmission throughout long operating intervals. The EPDM compound maintains flexibility across a wide temperature range, while the precision-formed profile contributes to quiet running and uniform engagement in multi-pulley systems. The combination of durable materials, accurate geometry, and low-stretch cord construction makes MARATHON X suitable for demanding engine layouts with variable loads and extended duty cycles.
