...Maosheng Wen; En Zhu Hu; Xingpeng Fei; Kunhong Hu Purpose This paper aims to use an ionic liquid (IL, [HMIM]PF₆) to improve the lubrication performance of liquid metal (LM) as a lithium grease additive and to expand the application range of LM. Design/methodology/approach...

...Ahmed Mobasher; Alaa Khalil; Medhat Khashaba; Tarek Osman Purpose The purpose of this paper is to evaluate the influence of nanoparticles as an additive on the tribological properties of calcium grease. Design/methodology/approach The nano additives in this research are with different...

...Bahaa M. Kamel; Alaa Mohamed; M. El Sherbiny; K.A. Abed Purpose The purpose of this paper is to fabricate composite nanogrease for tribological applications. Multi-walled carbon nanotubes (MWCNTs) with a size 10 nm average diameter and 5 μm in length were used as additives to calcium grease...

...-pressure (EP) additives in biodegradable lithium grease. The paper aims to discuss these issues. Design/methodology/approach – The tribological performances of the grease samples containing these derivatives are evaluated by using a four-ball tester. X-ray absorption near edge structure (XANES...

...Patric Waara Since the middle of the 1970s, lubrication of the high rail flange has been used to reduce wear rates. Field tests have been taking place since 1997 to evaluate the differences in wear characteristics between mineral oil based grease and new environmentally adapted greases. The field...

... Until recently, a major stumbling block in industry's uptake of biodegradable lubricants was that they were considered unsuitable for bearing lubrication. However, the new green grease meets SKF's stringent criteria for bearing grease. The green grease also differs from other biodegradable...

... with special emphasis given to interpretation and practical application. In Germany it is estimated that 2,000 tonnes of grease are lost to the environment each year mainly as a result of centralised lubrication systems now fitted as standard on many commercial vehicles. Clearly a similar situation exists...

...Jan Lundberg; Sven Berg New, undestroyed greases of the same brands as those used in a field test, described in Part 1, were examined using conventional methods, such as the SKF V2F test, the roll stability test (ASTM D‐1831), the Grease Worker (ASTM D‐217), the torque test (ASTM 1478‐91), bleeding...

...Jan Lundberg Describes a comprehensive field test to determine the best grease for spherical roller bearings in railway waggon wheels and increase the knowledge of grease lubrication. Nine different fully‐formulated commercial greases were examined in the wheel bearings of five ore waggons, used...

... highlighted. The last paper was presented by Mobil and reported on their development of improved lithium complex greases. This work will enable the company to offer an improved range of complex greases produced using an economically acceptable manufacturing process. This ELGI meeting lived up...

...Erik Kuhn This paper is concerned with the study of grease reaction by tribological stress. To observe the change of the viscoelastic properties by shearing the grease, rheometer tests were done. In addition to the flow behaviour, we investigated the friction process by using some tribometer...

... Completely self-contained,the unit contains l20cu.cm of Sapphire multi-purpose bearing grease or"Foodlube" bearing grease. It is simply screwed into a standard 1Ž4inch BSP union on a bearing housing or other lubrication point ­ and switched on. The Autolube will then supply ­ at a maximum...
