Developing a sustainable grease from jojoba oil with plant waste based nanoadditives for enhancement of rolling bearing performance

Scientific Reports
This paper presents a novel grease from jojoba oil and activated carbon nanoparticles (ACNPs) extracted from banana peel waste. The raw jojoba oil and ACNPs are first characterized for structural properties.

Grease lubrication mechanisms in bearing seals

, 2011
Rolling bearings contain seals to keep lubricant inside and contaminants outside the bearing system. These systems are often lubricated with grease; the grease acts as a lubricant for the bearing and seal and improves the sealing efficiency.

Design of a test rig for grease endurance tests

Results in Engineering
Background: The performance and endurance of lubricating greases is often assessed through model tests (like four-ball tests or SRV tests). This approach has some limitations, especially when greases with special fillers are investigated, because ...

Grease lubrication in radial lip seals [Elektronisk resurs]

, 2009
Rolling element bearings contain seals to keep lubricant inside and contamination outside the bearing system. These bearings are more often lubricated with grease rather than oil.
