VOITH 55.6336

VOITH 55.6336 – is an OEM approval from Voith Turbo GmbH that defines the requirements for hydraulic retarder systems and automatic transmissions of heavy vehicles. The specification calls for the use of class B oil with viscosity that provides stable torque transmission, high thermal resistance and wear protection under heavy loads, as well as compatibility with regenerative braking systems. It is targeted at diesel trucks, buses and special equipment, often equipped with particulate filters (DPF), where a low mineral content that does not contaminate the catalyst is required. Using oils that meet VOITH 55.6336 guarantees proper operation of retarder brakes, prevents premature bearing wear and maintains transmission performance stability under continuous braking cycles. On XENUM.ua you will find products such as XA‑TRAN DX VI and XA‑TRAN UNI that carry this marking and meet VOITH requirements.
