Shell Vitrea Oils 100 dầu bánh răng có khả năng chịu tải cao

Shell Vitrea Oils were discontinued some time ago. They were initially replaced with Shell Process Oils, which were ultimately replaced with Shell Morlina S1 B oils. Unfortunately along the way, various grades of the original Vitrea oils were dropped, and there is now no direct replacement for some of them.

To understand which oils can be used to replace the old Vitrea oils, it is worth understanding their category and viscosities.

Vitrea oils were a mineral oil based circulating oil suitable for general purpose lubrication. They did not contain any specialist EP additives that could harm yellow metal components so were suitable for use over a wide range of applications. Mobil DTE Named Series can be used as a suitable replacement for the lower ISO viscosities and Shell Morlina S2 B Series can be used as a replacement for the higher viscosities.

The Following table shows how the old Vitrea naming scheme was converted to ISO VG based names when ISO standardisation was introduced.

Applications
• Plain and rolling element bearings
• Enclosed spur, helical, bevel & worm
gearboxes where a non-additive mineral oil is approved by the gear manufacturer
• Machine tool circulatory systems
• Vitrea Oils may be used in industrial applications where loadings and temperatures are moderate.
Performance Features and Benefits
• Good water shedding properties.
• Long life in circulatory systems.
