Notes from the bench, not the brochure.
Dated analysis for grease plants, blenders and reliability engineers — thickeners, lithium alternatives, EPR, patents as prior art, and what a test method actually measures. Written by an independent formulation practice in New Delhi.
How to Choose Grease for a Cement Kiln, Girth Gear and Ball Mill
A cement line is three lubrication problems: slow, heavily loaded open gears that want a residual compound; hot kiln support rollers that…
Steel Mill Roll-Neck Bearings: Lithium Complex or Calcium Sulfonate?
Roll-neck bearings see water, scale, shock load and heat. Lithium complex is the Indian default; calcium sulfonate complex usually wins on water…
Open-Gear Lubrication in Mining: Compound, Spray or Grease?
Open gears want a lubricant that sticks, carries load and can be inspected. Asphaltic compounds, solvent-cut sprays and high-base-oil greases are three…
RDSO M-942 Railway Grease: What Indian Rail Vendors Must Put on the File
RDSO M-942 is a specification, not a brand. The file needs the stated thickener, penetration, drop point and performance tests — and…
Metalworking Sump Failure: Tramp Oil, Bacteria and When to Reformulate
A rancid sump is usually tramp oil plus bacteria plus a formula that cannot tolerate the water hardness it was sold into.…
Wind Turbine Main-Bearing Grease: Relube Intervals and Thickener Choice
A main bearing sees oscillation, moisture and a relube interval measured in months, not shifts. Lithium complex and some polyurea/PAO systems dominate.…
Grease for Parked Rail Stock: False Brinelling on the Siding
Wagons and metros spend long periods parked under vibration from passing traffic. That is a false-brinelling duty, not an RDSO running duty.…
Aluminium Complex Grease: Rolling Mills, Sugar and Food Contact
Aluminium complex sits in Lubechem’s capability table (drop point 250 °C+, water, food-contact) but has no dated explainer. It sprays well, resists…
