Mobilgear OGL Series

Grease

Mobilgear OGL 007, 009 and 461 are high performance advanced technology lubricants which incorporate both extreme pressure additives and finely dispersed graphite for load carrying.  They are intended primarily for the lubrication of large, slow to medium speed, heavily loaded gears.  In addition to providing outstanding load carrying, they are formulated to have excellent adhesion and resistance to "fling-off" under extreme conditions. Mobilgear OGL 007, 009 and 461 are easily pumped from drums to application spray nozzles with conventional transfer pumps.The soft consistency and the low temperature properties of Mobilgear OGL 007, 009 and 461 are suited to spray applications operating under a wide variety of conditions. Mobilgear OGL 007, 009 and 461 are formulated with a carefully specified quality of finely dispersed graphite which contributes significantly to wear prevention under the boundary lubrication conditions found in the high load / slow speed operations typical of large open gearing.

 

Features and Benefits

Mobilgear OGL 007, 009 and 461 are leading members of the Mobilgear brand of products that enjoy a worldwide reputation for performance and innovation.  Developed by ExxonMobil research scientists and backed by a worldwide technical support staff, Mobilgear OGL 007, 009 and 461 have provided excellent protection and performance in large open gearing in a wide variety of industrial applications. Mobilgear OGL 007, 009 and 461 were developed to meet the requirements of Original Equipment Manufacturers (OEMs) and the needs of customers who prefer to use a soft to semi-fluid grease for heavily loaded, slow to medium speed open gearing.  A critical need for products of this type is to separate the heavily loaded gear teeth and avoid surface wear and damage.  Mobilgear OGL 007, 009 and 461 are formulated with a specific quality of finely dispersed graphite which has been shown by our researchers to contribute significantly to the elastohydrodynamic (EHL) film thickness under the high load / slow speed conditions typical of large open gearing.
