SYNTHETIC OILS

There are currently six basic families of synthetic lubricants that are recommended for applications: Synthetic Hydrocarbons (SHC), Polyglycols, Organic Esters, Silicones, Fluoroethers and Polyphenylethers. Each synthetic family has its own unique characteristics.

On a general note, synthetic lubricants, both greases and oils can withstand much broader temperature extremes (upto +250 °C & -50 °C) than mineral-based lubricants. Synthetic oils demonstrate relatively low evaporation rates and high oxidation stability at high temperatures while maintaining low viscosity at low temperatures compared to mineral oil range.

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.

Synthetic Oils

Berusynth GP series are Polyalphaolefin based high performance synthetic gear oils available from ISO VG 69 to 1000 with good viscosity temperature behaviour. Berusynth GP range of gear oils provide excellent oxidation, shear stability, superior load carrying capacity and wear protection. With very high ageing resistance, Berusynth GP series allows for extended oil changing intervals.The gear oil series with reduced coefficient of friction results in lower sump temperatures, minimum power loss and extended oil change intervals.

Applications: These specially formulated gear oils are recommended for heavily loaded spur gears, bevel spiral and worm gears in rolling mills, paper mills and textile manufacturing units. Berusynth GP range also provide superior results in roller and plain bearing applications where operating temperatures are constantly above 100 °C.

Please consult a BECHEM Application Engineer for selection of the suitable grade of ‘Berusynth GP’ series for your application.

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

Short bytes for queries on lubricants that always bothered you

Emulsifiers help in increasing solubility of the cutting oil in water by breaking down the oil into smaller globules and thereby maintaining a stable and uniform emulsion. A stable emulsion provides longer tank life and also ensures lower carry over loss resulting in minimum top ups.

The basic function of a cutting fluid is to provide adequate lubrication to the tool and work piece friction zone as well as remove heat generated by cooling the deformation area. Some additional properties that are desired in the cutting fluid are,

  • Ability to rinse away the metal debris from the friction zone
  • Provide adequate protection against corrosion to the machine and work piece
  • Compatible to machine paint and ensure stain free machines
  • Easy to handle and comply to safety and environmental regulations

Intense amount of heat is generated between the grinding wheel and work piece due to friction and cutting process. Uncontrolled heat can lead to structural damage of the work piece and increase in wear rate of the wheel. Fine dust and metal debris are continuously generated and needs to be cleared out from the wheel, work piece interface. The cutting fluid for Grinding process should possess the right amount of lubricity and cooling property to reduce friction and manage temperature rise. Additionally the cutting fluid should also possess the right amount of detergency and flushing property to clear the fine machined debris.

With a higher dosage of lubricity to reduce friction and temperature rise, the coolant should also contain EP additives that can protect the tool by forming a thin layer between the tool and work piece. Additionally, the cutting fluid should possess the right amount of flushing property to clear the machined swarf from the machined area

Ideally, de mineralized (DM) water with neutral pH of 7 and hardness less than 50 ppm is recommended. The chloride level should be less than 25 ppm with no bacterial and fungal presence. Usage of hard water leads to increased conductivity, hence poor rust protection and lower sump life.

‘Oil into water’ or ‘oil in last (OIL)’ is a recommended practice for better solubility of the coolant in water. Water in oil would result in large size oil globules with the oil loving ‘oleopphilic’ ions of the emulsifier being ineffective. This would lead to a unstable oil water emulsion.

  • Keep a regular check on the concentration of the emulsion, maintain recommended concentration
  • Remove any tramp oil from the coolant tank thoroughly
  • Measure pH regularly
  • Avoid all sorts of dust near the tank, remove the machined debris from the tank regularly.
  • Follow the prescribed procedure while changing the coolant.

Including the effectiveness of ‘cutting fluid’, tool life is impacted by a host of other parameters including cutting speed, feed rate, depth of cut, tool and work material, nature of cut and machine rigidity. Cutting fluids with high amount of EP additives would insulate the tool from frictional wear and ensure longer life. Studies have shown that with all other parameters remaining the same, cutting fluids with good EP properties can increase tool life by 20 to 40%.

Aluminum alloys which contain Copper and Zinc as alloying elements are susceptible to chemical reaction (black stains) with cutting fluids that contain Amines as ingredient.  For machining such Aluminum alloys, amine free cutting fluids are recommended

Colour change of the emulsion is notable during machining of Cast Iron with the Fe ions dissolving with the emulsion. However with all other parameters such as pH, conductivity, concentration and microbial behavior remaining within the specified limits, colour change does not impact performance of the emulsion.

Operators handling components with bare hands and in constant touch with the emulsion could feel irritation and itchiness or develop rashes as well. As sensitivity of the skin is subjective, operators need to handle machined components with proper gloves and other protective gear with the objective of avoiding direct contact with the emulsion. Barrier creams could also be considered where direct contact is unavoidable.

Ensuring a stable emulsion with regular check on pH levels and microbial growth by removing chips, swarf and tramp oil from the tank will also help in reducing possibilities of such concerns. Encourage operators to maintain good personal hygiene, recommend regular laundry of their work dress, avoiding wet rags into pockets, usage of mild soaps etc.
