Extensive Range of Specialty Oils & Fluids

BECHEM’s extensive range of specialty oils and metal working fluids for industrial applications and metal working processes are developed with high quality base oils and advanced additive package.

The range of specialty oils are based on mineral as well as synthetic hydrocarbons including Polyalphaolefins (PAO) and Polyglycols (PG). Recommended for industrial gear boxes, heavy duty chains as well as oil lubricated plain and roller bearings, the specialty oils by BECHEM possess superior oxidation stability, high dosage of anti wear additives and excellent viscosity temperature behavior.

BECHEM’s range of specialty fluids cover the entire spectrum of metal working processes from moderate machining to severe cutting operation to wire drawing and tube forming processes. The new generation of metal working fluids by BECHEM provide long sump life, excellent surface finish and corrosion protection, extended tool life and best in class economy.

Berusynth range of synthetic oils by BECHEM are based on proven synthetics including Polyglycol, Polyalphaolefin (PAO) as well as Esters. Available in varied viscosities Berusynth’s advanced anti ageing formulation ensures extended lubricating life over wide operating temperatures for industrial gear boxes, heavy duty chains and other critical industrial applications.

BECHEM NSF H1 approved food grade oils are based on high performance synthetic oils and are capable of operating under high load carrying environment. BECHEM food grade oils offer reliable protection against corrosion of contacting surfaces.

Berusynth Chain oil series is recommended for long term lubrication of heavy duty chains that experience heavy loads, extreme operating temperatures as well as for meeting special requirements such as processing industries.

The Berugear, Staroil and Berusynth range of mineral and synthetic based gear oils by BECHEM offer superior performance by reducing friction and power loss as well as managing temperature rise.

Knitting is an intricate process by which consecutive loops or stitches are formed to turn yarn into fabrics. The needle and sinker which form the frictional partners in a circular knitting machine are exposed to severe stresses and demand special lubricating film.

BECHEM’s range of high viscous fluids are developed for heavily loaded applications such as gears and journal bearings. The fluids are adhesive in nature and naturally form a thick lubricating film between contact partners even under extreme loads.

The Berusynth range of synthetic oils with performance additives provide long service life for screw compressors. The PAO based oil with excellent thermal stability and ageing resistance extend draining intervals to 8,000 to 10,000 working hours.

BECHEM’s Avantin range are the most advanced breed of cutting fluids that have set new benchmarks in the industry by achieving maximum performance with minimal consumption. Fortified with advanced additives the Avantin series of cutting fluids are equipped to contend harsh external impurities such as hydraulic oil, swarf and grinding dust whilst delivering unmatched performance.

BECHEM’s range of neat oils have excellent EP and anti wear properties essential for increased tool life and achieve superior surface finish. Berucut and Berugrind range of neat oils by BECHEM possess excellent flushing properties and support high speed cutting. These special series are extremely resistant to ageing and provide longer sump life.

Beruclean range of cleaners by BECHEM developed with advanced formulation provide spotless and speck free components, leaving no residues mandatory for critical machining processes. The Beruclean range is available in both aqueous and solvent-based biodegradable variations for wide variety of materials.

BECHEM’s Unopol and Berudraw range are globally sought after lubricants for wire drawing processes of Copper and Aluminium alloys. These advanced lubricants provide superior lubricity ensuring excellent surface finish for drawn wires. The dynamic additive package extends the service life of the lubricant and drawing die as well

BECHEM’s MQL (Minimum Quantity Lubrication) range of advanced lubricants form a continuous film on the tool and metal job interface with the intention of reducing friction and thereby temperature build up. Berucut and Beruform range of MQL lubricants possess excellent lubricity as well as good flushing properties.

BECHEM’s range of cold forming oils have been developed after thoroughly understanding requirements of the customer and subsequently collaborating with machine manufacturers for superior product function.


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.
