Product Description
The Mobil Vacuoline 500 Series is a range of high-performance lubricants designed for marine equipment, specifically for circulation systems in gears and bearings. These oils are formulated with high-quality base stocks and proprietary additives to ensure superior wettability, oil retention, and protection against rust and corrosion. They offer excellent resistance to oxidation and thermal degradation, and are available in three viscosity grades.

Features and Benefits
The series is globally recognized for its outstanding performance and technical support. Key benefits include improved equipment reliability, reduced maintenance costs, excellent protection against rust and corrosion, and superior anti-wear performance. The oils also demonstrate excellent water separation characteristics, contributing to smooth operation and long oil life.

Applications
Mobil Vacuoline 500 Series oils are primarily used for lubricating plain and roller bearings, as well as parallel shaft and bevel gearing. They are suitable for systems not requiring extreme pressure performance and are effective in splash, bath, and ring oil arrangements. They are also recommended for hydraulic systems requiring higher viscosity oils and are resistant to high temperature exposure.

Typical Properties
The series includes three products: Mobil Vacuoline 528, 533, and 537, with ISO Viscosity Grades of 150, 220, and 320 respectively. Key properties include high viscosity index, low pour point, high flash point, and excellent rust protection in both distilled and sea water. They also exhibit zero foaming characteristics and pass copper corrosion tests.

Health and Safety
When used as intended and following the Material Safety Data Sheet (MSDS) guidelines, the product is not expected to have adverse health effects. It should not be used for unintended purposes, and proper disposal is necessary to protect the environment.
