Machinery Lubrication May 2007

I recently conducted a failure analysis and a reliability audit on a 300-kilowatt hydrostatic transmission. This hydraulic system was running a synthetic-ester, biodegradable hydraulic fluid and...

The main driving force since 1990 for the development of the entire API commercial "C" diesel engine oil classifications (for example, CF-4, CG-4, etc.) is the concern over the environmental impact...

At the heart of almost every industrial facility are electric motors, which can render equipment inoperative should their rolling element bearings fail—an occurrence more common than necessary due to strain resulting from improper lubrication. If you fail to consider all factors involved, your equipment will be predisposed to early

Today’s fleet managers are trying to get every mile possible out of their oil changes and regreasing intervals. Thanks to the advances in additive technology made in recent years, many heavy-duty engine oils and lubricant son the market do a great job of helping fleet managers extend interval times. But oil is only part of the solution. There are several other factors that must be considered.

The benefits of proper equipment maintenance and use of a high-quality heavy-duty diesel engine oil are evident at Miles Sand and Gravel, a sand and gravel supplier in Auburn, Washington. The...

This article describes some temperature-oriented methods for determining bearing health and life expectancy, both in the plant and in the field.

This article discusses the demands new machinery is placing on hydraulic oils and offers advice on what properties to look for when purchasing an oil to meet the challenge. Modern Conveniences...

Eliminate Cartridge Changes Consider this if your workshop stores grease in bulk, such as in a powerlube system. To save time and money on grease cartridges, and reduce waste with messy cartridge...

Each year at the NLGI Annual General Meeting, technical papers are presented on various subjects dealing with the manufacturing of greases, innovations in testing of greases, new...
