A Low Friction Thrust Bearing for Reciprocating Compressors [PDF]

, 2012
A thrust bearing with a micro texture on its sliding surface that produces hydrodynamic pressure was developed for use in reciprocating compressors. Evaluation using an elemental friction test showed that its friction loss was 20–60 % lower than that of ...

CONTINUOUS V/S RECIPROCATING FILE MOTION – A REVIEW

, 2017
Aim: To review the continuous and reciprocating file motions in endodontics Back Ground: The first endodontic file was crafted in the mid 1800’s. Thiis was basically a rudimentary k-file. K-files are, to these days.
