Protecting Bearings From Corrosion

In a humid environment, condensate can form in rolling element bearings and cause corrosion, leading to a reduction of the bearing life. The condensed moisture's effect can be reduced by carefully choosing the grease lubricant. Greases thickened with sodium soap will absorb (emulsify) large quantities of water, but may, however, soften it to such an extent that the grease flows out of the bearing.

Lithium soap greases do not emulsify water, but with suitable additives can provide good protection against corrosion. There are also a number of greases available containing synthetic thickeners that offer excellent protection against corrosion, prolonging the bearing life.

Is Water Getting Into Your Stored Grease?

From the book "Lubricating Grease Guide"

Contaminants can deteriorate greases. Unless containers are tightly sealed, prolonged storage increases the possibility that contaminants will enter stored product. The most prevalent contaminant is moisture, which can enter apparently sealed containers of grease, rusting the containers and changing the product. Some greases, such as soda soap greases, tend to soften when contaminated with water. On the other hand, traces of moisture have been known to cause clay greases and calcium complex greases to become firmer.

Appearance changes in storage are not a common problem but can become evident if oxidation causes the surface to darken, if air slowly leaves the product improving clarity, or if water causes the grease to become hazy.

Vertical Lube Oil Pumps (Model VCRE)

Lube oil pumping applications demand a pump that provides reliability and extended service life with a minimum of maintenance. The typical Lube Oil pump must also be capable of operation over a wide range of temperature and liquid viscosity conditions. The VCRE family of pumps is designed specifically with these requirements in mind. The VCRE lube oil pump is a vertically submerged pump that utilizes an ANSI standard hydraulic construction, enclosed bearing housing, and welded piping construction which eliminates the inherent maintenance and leakage problems associated with other pumps. During operation, axial and radial thrust loads are controlled by Buffalo’s exclusive modified casing volute and impeller design.  is backed by extensive field-proven experience in designing pumps to handle any lube oil application. This experience also provides flexibility in assisting OEM’s contractors and end-users in designing a sound instal...

Motorcycle Shaft Drive Grease

General Purpose Grease Grease has several uses on a motorcycle. It's there to protect parts from water, to keep rubber and plastic seals from drying out, and to provide lubrication. Generally speaking, grease is just a reduced fat. In fact, you can find several companies who call their grease bases "soap." The choice for a general purpose grease to protect from water, keep seals moist, and provide lubrication is easy. If you're going to do your own maintenance, I recommend you get Mobil-1 or Valvoline synthetic grease for general purposes, about $6 / pound anywhere. This stuff can handle temperatures higher and lower than you'll ever get near. A one pound jar should last you about 15 years. Shaft Drive Gear Maintenance There are two types of maintenance you must do on a shaft drive bike. At your rear wheel there are pinion gears where the spinning drive shaft motion is turned 90 degrees into the rear wheel motion. These gears are bathed in oil which much be c...

Understanding Ferrous Density

As part of my job, I regularly present oil analysis training seminars. One of the tests we discuss is ferrous density. I find that this test is seldom well understood, and, probably as a result, is seldom used. Explanation of the Test Ferrous density is the density of ferrous, or more correctly, of ferromagnetic particles distributed in the oil. The other ferromagnetic elements that one might encounter in lubricated components are nickel and cobalt, but in practice, these elements are likely to be present only in comparatively small quantities. Therefore, we are effectively measuring the concentration of magnetic steel alloys. There is no single way to conduct a ferrous density analysis. There are many ways of performing this rather essential test. Perhaps the two most common are the direct-reading ferrography, a technique which uses light blockage analysis of material deposited on a glass slide; and electromagnetic induction, which measures the voltage induced in a current-carrying ...
