Greases and Lubricants: Protecting Moving Parts and Extending Life

Greases and specialty lubricants reduce friction, prevent corrosion and extend the life of mechanical components. This category explains types of grease, application areas and selection criteria for automotive and industrial use.

Choosing the right grease

Identify the base type—lithium, calcium, synthetic or polymer—and the appropriate NLGI grade for the application. High-temperature bearings, chassis points and sealed units have different requirements, so match viscosity and water resistance to operating conditions. For routine maintenance, buying in larger tubs or multi-packs can be economical, but check batch dates and storage to maintain product integrity.

Application and maintenance best practice

• NLGI grade: select consistency that suits bearing speeds and loads.
• Base oil: synthetic greases offer improved high-temperature stability.
• Compatibility: avoid mixing incompatible greases to prevent performance loss.
• Sealing: ensure seals and fittings keep contaminants out.
• Storage: keep containers clean and sealed to avoid contamination.

Apply grease with proper tools and follow recommended intervals to prevent premature wear. For specialist applications, consult manufacturer guidance or a technician to ensure the chosen lubricant meets performance and safety requirements.
