Marathon chains for extreme conditions: safe, maintenance-free, durable
Apart from availability, operational safety and reliability, the fact that components are maintenance-free is getting more and more important in machine and plant construction. The use of Marathon chains always makes sense where relubrication of roller chains is either not possible or not desired, but where, nevertheless, a long life cycle is required.
For application areas with certain chain speeds and operating temperatures Wippermann can provide optimal solutions with Marathon chains. They work with a porous, oil-soaked sintered bushing, which is combined with a specially-coated pin to form a self-lubricating chain joint.
The dimensions of Marathon chains are according to ISO 606 so that every standard roller chain can be replaced by a Marathon chain. The breaking load of a Marathon chain exceeds the requirements of respective standards and is comparable to Wippermann standard chains as regards fatigue resistance.
Apart from the standard roller chains according to ISO 606, the Marathon range also comprises roller chains type series GL with straight plates, double-pitch roller chains according to ISO 1275 and accumulator chains.
