It can be argued that lubricants are the lifeblood of equipment. It is extremely difficult to assure equipment reliability when lubrication integrity is not maintained. The key is to keep the lubrication system clean, cool and dry.
According to the Arrhenius Rate Rule, every 18-degree (F) increase in oil temperature in operation reduces oil life by half. Excessive lubrication temperatures can lead to additive depletion, oxidation, varnishing, hazards, corrosion, increased frequency of oil changes and more. All of this leads to reduced equipment reliability and increased costs.
Reduced operating temperature is one of the many benefits associated with proper machinery alignment. This in turn will help you reduce the operational temperature of the lubricants (lifeblood) within your equipment. Best practice equipment reliability includes proper equipment alignment. Your best practice lubrication efforts should include making sure your equipment is operated within proper alignment tolerances. Doing so will help you maintain the "cool" required to ensure that the lifeblood of your equipment is protected.
