Industrial Grease

Minimize The Risk of Bearing Failure Due to Heat

04_img_3026_357x233A bearing is a basic element of numerous machineries. A whole process can get impeded as a result of a bearing failure. The top quality bearings are constructed to last a very long time. If operating under the correct conditions and adequately taken care of, the bearings really should be one of the last components of the hardware to fail over the course its lifespan. But operating under the best conditions does not happen often. The limited room in most factories or workshops leads to working environment that is hotter than ideal and the risk of contamination also increases. The industrial grease within the bearing which protects it from mechanical and chemical wear can degrade very quickly when contaminated or exposed to an abnormal level of heat.

It is important to employ measure that protect against bearing failure caused by heat problems. A good place to start is by reorganizing the workshop and processes in such a way that heat is maintained to suitable levels. The working environment must also be kept clean as much as possible. Processes that generate plenty of dust particles can be placed in a more secluded area to avoid affecting the more sensitive pieces of equipment.

As the bearing lubricant starts to deteriorate, its lubricating capability suffers. It will not have the ability to lubricate bearing components as well as it used to. This leads to greater creation of heat which is serious threat to the health of the bearings. The warped races can then hinder the entire movement of the bearing.

Industrial Grease and Applicability

DrillingThe grease is integral to various industrial processes. Even the most advanced machines can fail due to issues related to lubrication. A lubricant such as grease must be able to withstand the operating conditions to prevent failure. The industrial grease is a lubricant designed to handle the tough industrial conditions such as intense heat, heavy loading and high speeds.

The industrial grease is composed of the base oil, additives and thickener. The base oil is responsible for lubrication. Additives give extra properties such as improved loading or resistance to conditions like heat and moisture. The base oil and additives are blended together to create a homogenous mixture. The thickener acts like a sponge that can release and reabsorb the mixture of oil and additives depending on the presence or absence of mechanical and thermal stresses. The viscosity of the grease allows it to stay within the lubrication point even without seals, unlike lubricating oil.

The applicability of grease is limited by the risk of contamination. Grease is like a magnet to dust, shavings and other contaminant particles. The presence of contaminants in the grease can cause performance problems. This makes grease unsuitable for operating environments with large amount of contaminants.

In the inapplicability of grease,  solid film lubricants are used. There are various solid materials with natural lubricating capability that are used for high-contaminant environments. The most commonly used are molybdenum disulfide, graphite and PTFE. This type of lubricants are applied to surfaces similar to paint.
