  1. 1. Grease lubrication in radial lip seals

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Pieter Baart; Luleå tekniska universitet.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Elements; Maskinelement;

    Abstract : Rolling element bearings contain seals to keep lubricant inside and contamination outside the bearing system. These bearings are more often lubricated with grease rather than oil. Much knowledge is available on oil lubricated seals but a good understanding of grease lubricated seals is lacking. READ MORE

  2. 2. Tribological Aspects of Pneumatic Clutch Actuators

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Frida Riddar; Uppsala universitet.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wear; friction; PTFE transfer; anodised aluminium; NBR rubber lip seal; silicone grease; casting; extrusion; Teknisk fysik med inriktning mot tribomaterial; Engineering Science with specialization in Tribo Materials;

    Abstract : A clutch actuator is used in a vehicle to transmit movement and force from the clutch pedal to the release bearing of the clutch. A pneumatic clutch actuator consists of an anodised aluminium cylinder, inside of which a piston, with a rubber lip seal and a PTFE guiding ring, slides. The system is lubricated with silicone grease before assembly. READ MORE

  3. 3. Grease lubrication mechanisms in bearing seals

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Pieter Baart; Luleå tekniska universitet.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Elements; Maskinelement;

    Abstract : Rolling bearings contain seals to keep lubricant inside and contaminants outside the bearing system. These systems are often lubricated with grease; the grease acts as a lubricant for the bearing and seal and improves the sealing efficiency. In this thesis, the influence of lubricating grease on bearing seal performance is studied. READ MORE
