Lubrication applied to industrial gear system
Anti-Wear: Stops mechanical wear by preventing direct contact of metal parts with each other. Heat Control and Cooling: It prevents overheating by absorbing the heat generated in systems operating under high speed and pressure. Corrosion Protection: Protects equipment surfaces from the oxidizing effects of moisture, water and harmful chemicals. Energy Efficiency: When the friction in the system is reduced, the machines perform at their maximum by consuming less energy.
How to choose hydraulic oil: ISO VG, additive class and cleanliness
Most hydraulic failures come from the fluid: wrong viscosity, wrong additive or contamination. Finding the right ISO VG, knowing the HL/HM/HV difference and setting a cleanliness target.
How to choose grease: NLGI grade, thickener type and dropping point
Oil flows away; grease stays put. The right grease has the correct consistency (NLGI), thickener type, base oil viscosity and temperature range. Bearings, chassis and high-temperature applications.
Antifreeze and engine coolant: colour misleads, chemistry matters
Antifreeze does more than stop freezing; it raises the boiling point, holds off corrosion and lubricates the water pump. The IAT, OAT and HOAT difference, the right concentration, mixing risk and change interval.
Automatic transmission fluid (ATF): what it does, and is "lifetime" really for life?
ATF is a different fluid from engine oil: hydraulic medium, lubricant, coolant and friction controller. Why it needs a specific approval, what "lifetime" really means, and when to change it.
When to change engine oil: mileage, time or how you drive?
In a lightly used car the oil degrades before the mileage is reached; stop-start city driving wears it as much as a long trip. Fixed service intervals, "long life" servicing, the short-trip effect and oil analysis.
Engine oil viscosity: what do 5W-30 and 10W-40 mean?
The 5W-30 on the bottle is not random. What the two numbers of the SAE viscosity grade tell you, which engine needs which, and what the wrong grade does.
What is Industrial Lubrication?
The right industrial oil reduces failures, lowers maintenance cost and protects production continuity. Selection criteria and maintenance intervals.
