Effect of Formulation of Li Greases on Their Flow and Ball Bearing Torque
Tribology Online, 2016 This paper describes a study on the effect of base oil type and thickener type on bearing torques with Li type greases. Using a ball bearing tribometer equipped with a torque sensor, friction torque behaviors were determined for model Li greases with ...

Formulation of biogrease from castor waste [PDF]
, 2014 Grease is a mixture of a fluid lubricant usually petroleum oil and a thickener (soap) dispersed in the oil. The base oil (petroleum) can be changed by using the castor waste. Other than base oil, thickener may play an important role in the mixture.

Per‐ and Polyfluoroalkyl Substances and Knee Osteoarthritis: Data From the Osteoarthritis Initiative
Arthritis &Rheumatology, EarlyView.Objective To examine whether concentrations of specific per‐ and polyfluoroalkyl substances (PFAS) and a mixture of PFAS relate to incident knee osteoarthritis (KOA) and knee pain progression. Methods Among a case‐cohort sample from the OA Initiative (n = 1,878), we examined associations of serum concentrations of eight PFAS with odds of developing ...

Techniques for Large, Slow Bearing Fault Detection
International Journal of Prognostics and Health Management, 2016 Large, slow turning bearings remain difficult to analyze for diagnostics and prognostics. This poses a critical problem for high value assets, such as drilling equipment top drives, mining equipment, wind turbine main rotors, and helicopter swash plates.
