Key Performance Characteristics

Excellent Oxidation Stability
7018 grease exhibits outstanding resistance to oxidation, effectively preventing grease degradation and hardening under high-temperature operating conditions. This property helps maintain stable consistency and lubricating performance over extended periods, reducing the risk of bearing failure caused by lubricant deterioration.

Superior Mechanical Stability and Adhesion
With excellent resistance to mechanical stress, the grease maintains its structure under high-speed operation and repeated shear forces. Its appropriate adhesion ensures that the lubricant remains in place on bearing surfaces, minimizing grease loss and ensuring continuous lubrication even at high rotational speeds.

Reliable High and Low Temperature Performance
7018 High-Speed Bearing Lubricating Grease provides stable lubrication across a broad temperature range. It maintains adequate fluidity at low temperatures and resists softening or oil separation at higher temperatures, ensuring that bearings operate smoothly and efficiently under varying thermal conditions.

Good Water Resistance
The grease demonstrates good resistance to water spray and washout, making it suitable for bearing lubrication in humid or damp environments. This characteristic helps preserve the lubricating film and protects bearing surfaces from corrosion caused by moisture exposure.

Excellent Lubricating Properties
7018 grease forms a strong and stable lubricating film that effectively reduces friction and wear between bearing components. This contributes to improved bearing efficiency, reduced energy consumption, and extended equipment service life.

Balanced Overall Performance for Long Bearing Life
Thanks to its comprehensive performance advantages, 7018 grease supports long-term, reliable operation of high-speed bearings. It is particularly effective in applications where consistent lubrication, low friction, and durability are essential.
