High loads with constant exposure to dust and high temperatures characterize operation of an indurating machine at Sinter and Pellet plant. Addressing a customer concern of repetitive bearing failures, It was observed that due to high temperatures the bearings in applications such as trolley wheel and slide track experienced lubricant starvation due to oxidation leading to premature bearing failures and leakage in sealings respectively.

Grease for this high temperature application area needs to maintain its viscosity at elevated temperatures and also should be able to retain high strength film between friction partners to withstand generated loads. Berutox range by BECHEM are developed in combination with mineral and synthetic base oils with comprehensive additive package to resist oxidation and provide efficient lubrication at high temperatures.

Applications and Properties

The unique pictograms help identify primary characteristics of the lubricant as well as key applications and industries it has been established at a glance. However the final recommendation would still have to be by the BECHEM specialist after having studied application and its operating environment. As the saying goes, ‘every problem has a unique solution, if only, one is looking for it’. This is the core philosophy to our approach towards ‘Application Engineering’ and staying true to ‘speciality’

Frequently Asked Questions

Greases are made by mixing a solid material, called a thickener, with a base oil and property enhancing additives; but it’s the oil that forms the lubrication film. For better understanding, grease thickener can be thought of as a sponge saturated with oil. Moving parts squeeze the oil out of the sponge like thickener for forming the lubrication film. Typically, the base oil constitutes the largest proportion of grease weight at about 80-90%, followed by thickener at 10 to 20% and additives under 10%.

Dropping point of a lubricating grease is an indicator of the heat resistance of the grease. and is the temperature at which the grease is no more a thickened lubricating medium. The dropping point indicates the upper temperature limit at which a grease retains its structure, not the maximum temperature at which a grease may be used.

Few greases have the ability to regain their original structure after cooling down from the dropping point.

The most important feature of a grease is its consistency. A grease that is too stiff may not get pumped into areas requiring lubrication. While a grease that is too fluid may leak out. Grease consistency depends on the type and amount of thickener used and the viscosity of its base oil. A grease consistency is its resistance to deformation by an applied force.

The measure of consistency is called penetration. Penetration depends on whether the consistency has been altered by working. Standard test procedures established by American Society for Testing and Materials International (ASTM) and accepted by industry are ASTM D 217 and D 1403, measure penetration of unworked and worked greases.

The NLGI has established consistency numbers ranging from 000 to 6, corresponding to specified ranges of penetration distance of the standard cone into the test grease. Table below lists the NLGI grease classifications along with a description of the consistency of each classification.

Viscosity: It is a measure of resistance to flow of a lubricating oil.

Viscosity index: It is defined as rate of change of viscosity with respect to temperature.


  • It is the most important property which determines the performance of lubricating oils under the influence of temperature
  • A lubricating oil should have sufficient viscosity to retain a lubricating film on the surface
  • On machine part moving at slow speeds under high pressures, a high viscous oil should be used as it better resists being squeezed out from between the rubbing parts.  Light oils can be used for lower pressures and high speeds.
  • It is not possible to maintain a liquid oil film between two moving or sliding surfaces if the viscosity is too low and hence excessive wear will occur.

The pour point of an oil is the minimum temperature at which the oil turns into semi solid and almost losses its flow characteristic. At low temperatures, the viscosity of the oil will be very high, causing the oil to resist flow. This is important in equipment that operates in a cold environment or handles cold fluids.
