Patent number: 9850952Abstract: A bearing assembly comprising a rolling element bearing having a first row of rolling elements arranged in a first bearing cavity between a first inner raceway and a first outer raceway of the bearing, and having a second row of rolling elements arranged in a second bearing cavity between a second inner raceway and a second outer raceway of the bearing. The assembly further comprises an annular grease cartridge arranged between the first and second rows of rolling elements. The annular grease cartridge is at least partly formed from a honeycomb structure having axially extending passageways filled with a grease lubricant, wherein at least some of passageways are open towards the first and second bearing cavities.Type: GrantFiled: July 3, 2013Date of Patent: December 26, 2017Assignee: AKTIEBOLAGET SKFInventors: Jos Holsnijders, Maurizio Martinetti, Filip Rosengren

Patent number: 7096923Abstract: A segment roll for use in a continuous casting machine includes a number of roll segments axially spaced apart and supported in bearings on a non-rotating shaft. Each roll segment is a self-contained unit including a sleeve-shaped outer mantle, an internal sleeve disposed coaxially within the outer mantle, and a bearing assembly disposed radially between the outer mantle and the inner sleeve within an annular recess disposed at each end of the roll segment. Each bearing assembly is spaced from an inner envelope surface of the internal sleeve and includes a bearing and a seal, wherein the internal sleeve is in non-rotatable contact with the non-rotating sleeve.Type: GrantFiled: December 1, 2004Date of Patent: August 29, 2006Assignee: Aktiebolaget SKFInventors: Magnus Axelsson, Jens Bode, Renato D'Uva, Patrik Costa, Filip Rosengren

Patent number: 6149312Abstract: A roller bearing comprising an inner and an outer ring in concentrical arrangement, a series of roller elements being arranged in the space between said rings and being in contact with raceways provided in said rings. The bearing is characterized in that said raceways are provided with parallel grooves, each one of said grooves being arranged in the plane of rotation of said rings and extending along the entire envelope surface, and in mutual correspondence to said inner and outer rings and being arranged for mating interaction with protruding flanges of said roller elements corresponding to said grooves, said protruding flanges extending along the entire envelope surface of said roller elements.Type: GrantFiled: December 22, 1998Date of Patent: November 21, 2000Assignee: SKF Nova ABInventors: Clair Druet, Vello Klaassen, Filip Rosengren

Patent number: 6150305Abstract: The present invention includes a lubricated bearing which incorporates a phase convertible compound. The compound absorbs and stores heat generated during operation of the bearing. This absorbs and stored heat is then released upon start-up conditions of the bearing, especially under low temperature conditions. The released heat is used to improve the ability of the lubricant contained within the bearings to reduce friction of the relatively movable parts contained therein.Type: GrantFiled: December 2, 1998Date of Patent: November 21, 2000Assignee: SKF Nova ABInventor: Filip Rosengren
