20090008882 | GASKET FOR A HYDROSTATIC LINEAR GUIDE | 01-08-2009 |
20090026714 | SEALING STRUCTURE AND SPIDER JOINT - A lip portion consists of two cylindrical axial lips | 01-29-2009 |
20090102136 | BEARING SEAL WITH FLEXIBLE LIP - A seal is disclosed for use on the tapered section of a roll neck in a rolling mill. The seal comprises a flexible circular seal body having a central axis and at least one radially outwardly extending flange joined by a hinge to an angularly extending lip. The hinge has a reduced thickness as compared to the thicknesses of the flange and the lip, and the lip has converging first and second sides leading to an enlarged rim. The rim has first and second peripheral faces that converge to an outer edge contained in a reference plane parallel to the central axis of the seal body. | 04-23-2009 |
20100038864 | SEALING DEVICE - A sealing device with a side lip contacting with a surface angled relative to its axis in which the cross sectional shape of the side lip is optimized. Where the thickness of the tip end ( | 02-18-2010 |
20100201078 | SEALING DEVICE - A sealing device includes a side lip contacting with a surface angled to the axis. To optimize the cross sectional shape of the side lip, T | 08-12-2010 |
20120153575 | Sealing Ring - A radial shaft sealing ring for the sealing separation of an internal space ( | 06-21-2012 |
20140021687 | Lip Seal With Inversion Prevention Feature - A dynamic shaft seal assembly is provided including a dynamic seal for engaging a rotary shaft. The dynamic seal includes a mounting portion that is mounted within a casing and has an axially extending barrel portion extending from a radially inner end of the mounting portion. The axially extending barrel portion terminates in a radially extending leg portion which extends inwardly from an end of the axially extending portion. A generally conically shaped seal portion extends from an end of the radially extending portion and the seal portion includes a radially inner face engaging the shaft and a radially outer face having a stiffening bead integrally formed thereon. The mounting portion defines a bumper spaced from the axially extending barrel portion by a gap distance that is designed to prevent the seal lip from inverting under sustained high pressure or pressure spikes. | 01-23-2014 |
20150354705 | ARRANGEMENT WITH A RADIAL SHAFT SEAL HAVING A SINUSOIDALLY CURVED SEALING EDGE - An arrangement includes a radial shaft seal ( | 12-10-2015 |
20160146351 | Rosette lipseal - A mechanical lip seal assembly preventing leaking oil and similar fluids from rotary shafts in gearboxes. This lip seal assembly comprising in combination a casing commonly made of metal which in turn contains a resilient lip seal element made of low friction plastic such as PTFE. This invention describes a resilient lip sealing element structure along in combination with a flat metallic rosette spring washer where inner and outer diameters are connected by isolated angular nodes which in turn this rosette spring is compressed onto low friction plastic sealing element containing pressure balancing and pressure transfer grooves located on opposite surface where the metallic rosette spring is compressed into. | 05-26-2016 |
