Sealing of Dry Particles with Grease-Filled Non-Contacting Sealing Systems

open access: yesLubricants, 2017
There is no wear and no friction with non-contacting sealing systems. Because of this, there is in principle no lifetime-limit. However, this does not apply for grease-filled labyrinth seals.

Non-metallic brush seals for gas turbine bearings [PDF]

open access: yes, 2004
A non-metallic brush seal has been developed as an oil seal for use in turbomachinary. Traditionally labyrinth-type seals with larger clearances have been used in such applications. Labyrinth seals have higher leakage rates and can undergo excessive wear

Stamina of a non-gasketed flange joint under combined internal pressure, axial and bending loading : an experimental study [PDF]

open access: yes, 2009
The performance of a bolted flange joint is characterized mainly by its 'strength' and 'sealing capability'. A number of numerical and experimental studies have been conducted to study these characteristics under internal pressure loading conditions alone.

Friction predication on pin-to-plate interface of PTFE material and steel

open access: yesFriction, 2018
In this paper, the friction behavior at a pin-to-plate interface is investigated. The pin and plate are made of Polytetrafluoroethylene (PTFE) and steel, respectively, and there is a reciprocating motion at the interface.
