Study on Atomization Mechanism of Oil Injection Lubrication for Rolling Bearing Based on Stratified Method

open access: yesLubricants
The atomization mechanism of lubrication fluid in rolling bearings under high-speed airflow between the rings was investigated. A simulation model of gas–liquid two-phase flow in angular contact ball bearings was developed, and the jet lubrication ...

Studies on Lubrication of Ball Bearing with Oil Jet (3rd Report)

open access: yesTransactions of the Japan Society of Mechanical Engineers, 1953
In the previous paper we reported results of the experiment on forced lubrication for the purpose of cooling of ball bearing, but applied load on the bearing was light. We repeated the same experiment as previously reported at higher load. Further we measured change of electric contact between outer and linner races of the bearing and obtained some ...

Treatment with Plasma Activated (Salt) Water Sterilizes Macromolecular Coatings While Maintaining Their Integrity and Functionality

open access: yesAdvanced Materials Interfaces, Volume 13, Issue 3, 3 February 2026.
PDMS samples were covalently coated with mucin glycoproteins and then treated with either plasma activated water (PAW) or saline (PAS) as a means of disinfection. The samples could be successfully sterilized without compromising the structural integrity or functionality of those coatings.
