Long-term greases
Long-term greases for bearings and joints are specialized lubricants designed to provide extended protection and effective lubrication without the need for frequent reapplication.
These greases are essential in various industries where regular access to components for maintenance is difficult or impossible.
Key properties of long-term greases:
- Thermal stability: The ability to maintain the consistency and lubricating properties of the grease at both high and low temperatures.
- Oxidation resistance: Resistance to oxidation that prevents the grease from hardening and degrading due to chemical reactions.
- Wear resistance: High resistance to mechanical wear, extending the service life of bearings and joints.
- Corrosion protection: Protection of metal surfaces from corrosion, which is crucial in aggressive or damp environments.
- Water resistance: Resistance to water, ensuring the effectiveness of the lubricant even in wet conditions.
- Low volatility: Low evaporation rate, preventing the grease from drying out over long periods.
Some of the materials used in long-term lubricants:
- Synthetic base oils: Such as polyalphaolefins (PAO) or esters, which provide excellent thermal stability and long service life.
- Thickeners: Thickeners like lithium complex soaps or polymers, which help maintain the structure and consistency of the lubricant.
- Additives: Special additives such as anti-wear agents, antioxidants, and corrosion inhibitors, which enhance the performance and protective properties of the grease.
