Description
Castrol Optigear RMO High performance long-term gear oil ISO VG 150
OPTIGEAR™ RMO is a multi-grade, high performance and long-term gear oil, especially developed for drive units in railborne traffic and machine construction at extreme climatic conditions. Low temperatures down to – 40°C/- 40°F can be handled without preheating the gears.
Application
All kinds of spur gearings even when subjected to the most extreme loads. Bevel gear pairs, also conical (hypoid) and at high changing loads.
Dip lubrication at high speeds as well as injection and oil mist lubrication.
Advantages
- High load carrying capacity and wear protection.
