Testing of a Large Adjustable Hydrodynamic Journal Bearing [PDF]
Tribology Transactions, 2001 The design and testing of two novel adjustable hydrodynamic journal bearings are outlined. Each was designed to replace a conventional bearing in a large marine gearbox. They were tested in a land based rig and their performances compared with that of the conventional bearing.

Investigation of the Wear Resistance of a Journal Bearing with Polymer-Coated Grooved Support Ring
Advanced Engineering Research, 2023 Introduction. In modern heavy-loaded friction units, metallopolymer coated bearings operating in the boundary friction mode are widely used. Their successful application is provided by the viscoelastic deformation of these coatings under load.

Reliability of a Hydrodynamic Journal Bearing [PDF]
Applied Mechanics and Materials, 2015 Journal fluid bearings are widely used in industry due to their static and dynamic behavior and their very low coefficient of friction. The technical requirements to improve the new technologies design are increasingly focused on the indicators of dependability of systems and machines.

Vibration control of rotors mounted in hydrodynamic bearings lubricated with magnetically sensitive oil by changing their load capacity [PDF]
Bulletin of the Polish Academy of Sciences: Technical Sciences, 2021 Rotors of rotating machines are often mounted in hydrodynamic bearings. Loading alternating between the idling and full load magnitudes leads to the rotor journal eccentricity variation in the bearing gap.
