High temperatures and heavy loads are challenges that require the right choice of lubricants. High-temperature greases, such as ceramic, copper, graphite, and molybdenum disulfide greases, offer various properties and applications to meet the demands of harsh working conditions. The proper choice of grease not only enhances performance but also extends the lifespan of mechanisms exposed to extreme conditions. Below are the key properties of each of these greases.
Why are proper high-temperature greases essential?
Mechanisms exposed to high temperatures, such as brake systems, engines, and exhaust systems, require specialized greases that can withstand harsh working environments. High-temperature greases must protect against friction, wear, and corrosion while maintaining their properties even in extreme conditions. Standard greases cannot handle such environments, making the selection of specialized greases absolutely necessary.
Ceramic grease – protection in extreme temperatures
Ceramic grease stands out for its resistance to extreme heat, up to 1400°C. It’s an ideal solution for exhaust systems, brake systems, and heating installations. In these applications, protection against seizing and corrosion is a priority.
Main benefits:
- Working temperature range: -30°C to 1400°C
- Effective protection against seizing and corrosion
- Applications: exhaust systems, brake systems, engines
Graphite grease – excellent friction protection
Graphite grease, enriched with graphite particles, ensures excellent resistance to friction and heavy loads. It’s a great choice for mechanisms like leaf springs, gears, and chains, where high friction resistance is crucial.
Main benefits:
- Excellent friction resistance
- Protection against corrosion and moisture
- Applications: leaf springs, gears, chains
Copper grease – corrosion and high-temperature resistance
Copper grease, operating in temperatures up to 1000°C, provides excellent corrosion protection even in moisture and salt-exposed environments, such as port equipment.
Main benefits:
- Working temperature range: -20°C to 1000°C
- Effective corrosion protection, even in marine conditions
- Applications: bolts, nuts, marine equipment
Grease with molybdenum disulfide – friction reduction in harsh conditions
Grease with molybdenum disulfide creates a protective layer on metal surfaces, minimizing wear in mechanisms like suspension systems, joints, and vehicle chassis.
Main benefits:
- High resistance to friction and wear
- Protection against washing out and abrasion
- Applications: suspensions, steering systems, chassis
