HIGH SPEED GREASE

High speed bearings operate under the hydro dynamic lubrication regime. Lower base oil viscosity coupled with special thickener types offer the lowest internal friction that is necessary in such high speed applications.  D * N factor is the deciding criteria for the rated base oil viscosity.

BECHEM’s range of high speed greases with low base oil viscosity and select thickeners have the ability to maintain desired film thickness even at high RPM’s. Smooth structure of the grease provides minimal internal friction and thereby lesser temperature build up. BECHEM’s range of high speed greases are formulated up to a D * N factor of 15,00,000.

High Speed Greases

Synthetic high performance grease with high speed index for high speed applications and spindle bearings. Berutox FB 22 provides long term lubrication even under extreme temperatures and operating conditions. Synthetic PAO base oil in FB 22 ensures extended service life. Smooth structure of FB 22 ensures minimal internal friction translating to reduced start-up torque and therefore less temperature build up. FB 22 provides superior corrosion protection as well as excellent resistance to alkaline coolant attacks. Extreme pressure additives offer good lubrication under medium to high loads and vibrations.

Applications: Recommended for lubricated for life bearings that demand fully synthetic base oil grease. FB 22 is compatible with commonly used sealing and cage materials. Recommended for high speed spindle bearings Example : In machine tools, threaded spindles, toothed gear in small gears, worm gear etc.

Frequently Asked Questions

Short bytes for queries on lubricants that always bothered you

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.

Significance:

  • 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.
