| 384551000 | Discrete circumferential or axial spacer | 11 |
| 20080240641 | Roller bearing - The clearance between the outer peripheral surface of an annular portion of a cage and the inner peripheral surface of each of rib portions of outer-ring split pieces is set to be smaller than the clearance between the radial end surface of a projection portion of the cage and the inner peripheral surface of each of body portions of the outer-ring split pieces. When a centrifugal force due to engine rotation acts upon the cage, the inner peripheral surface of each of the rib portions of the outer-ring split pieces touches the outer peripheral surface of the annular portion of the cage before the inner peripheral surface of each of the body portions of the outer-ring split pieces touches the radial end surface of the projection portion of the cage. Thus, the radial displacement of the cage can be prevented in good time. | 10-02-2008 |
| 20090252448 | Roller bearing - A roller bearing having spacers interposed between its rollers is provided, which has a high permissible rotational speed which is achieved by allowing a lubricant to flow smoothly around rolling surfaces so that the stirring resistance of the lubricant due to the spacers is reduced. | 10-08-2009 |
| 20090297084 | Preset wheel bearing arrangement - A wheel bearing arrangement has a spindle having inboard and outboard portions, where the outboard portion cooperates with a fluid driven motor and a land connects the outboard portion and the inboard portion. The wheel bearing arrangement further has inboard and outboard bearing systems located radially outb from the land. Each bearing system has a bearing located between inner and outer races, where the inner race contacts the spindle land and the outer race contacts a wheel hub. In addition, a spacer is located between the two bearing systems, where the spacer extends from the land to a radially inwardly extending hub portion and where the spacer sets the preload on both bearing systems and diffuses inboard traveling fluid pressure spikes. A spindle nut is located outboard from the outboard bearing system to secure the bearing systems on the spindle. | 12-03-2009 |
| 20110033147 | Bearing Assembly - A bearing assembly includes a first bearing comprising a first inner ring and a second bearing comprising a second inner ring. A sleeve-shaped spacer is disposed between and axially separates the first and second inner rings. An adhesive connects the spacer to the first and second inner rings. | 02-10-2011 |
| 20130301973 | TOROIDAL SPACER - The present invention relates to a spacer device for roller elements in a toroidal roller bearing, and a method for manufacturing a toroidal roller bearing comprising a plurality of spacer devices. The toroidal roller bearing allows for axial and angular displacement between an inner and outer bearing ring. The spacer device provides first and second roller-contacting surfaces having a concave shape adapted to conform with respective convex contacting surfaces of the toroidal roller elements, and at least one axial end portion which is elastically deformable. | 11-14-2013 |
| 20140016890 | BEARING DEVICE FOR MOTION GUIDE DEVICE - A motion guide device includes a rolling passage formed between two members, a number of cylindrical roller bearing members disposed in the rolling passage and engaged between the members, and a number of spacers disposed in the rolling passage and engaged between the cylindrical roller bearing members, the spacers each include two opposite curved depressions for engaging with the cylindrical outer peripheral surfaces of the cylindrical roller bearing members, and each defined by a planar middle surface, a tilted upper surface and a tilted lower surface inclined relative to the planar middle surface and the vertical axis (Z) of the spacer for selectively engaging with the cylindrical roller bearing members. | 01-16-2014 |
| 20140037241 | METHOD FOR PRODUCING A FLANGED DISK FOR A SPHERICAL ROLLER BEARING AND A SPHERICAL ROLLER BEARING HAVING A FLANGED DISK PRODUCED ACCORDING TO THE METHOD - A spherical roller bearing having a flanged disk designed as as hollow body, formed from a straight pipe section that is bent to for a ting having two ring ends that are joined. The ring is shaped into a flanged disk with a desired axial section geometry in a pressing device with a contour tool in a single pass. | 02-06-2014 |
| 20140050433 | METHOD FOR MANUFACTURING A ROLLING-ELEMENT BEARING ASSEMBLY AND A ROLLING-ELEMENT BEARING ASSEMBLY FORMED THEREBY - A method for manufacturing a rolling-element bearing assembly includes providing a first bearing ring, a second bearing ring and rolling-elements, rotating the first bearing ring relative to the second bearing ring and joining the first bearing ring, the second bearing ring and the rolling elements while the first bearing ring is rotating relative to the second bearing ring. The method additionally includes connecting one of the bearing rings to a bearing ring of another rolling-element bearing or to a spacer while the first bearing ring is rotating relative to the second bearing ring. | 02-20-2014 |
| 20150345559 | SPACER FOR ROLLING BEARING, NOTABLY USED IN A WIND TURBINE - The spacer is adapted for a rolling bearing comprising an inner ring, an outer ring and at least one row of angular contact rollers disposed between raceways and guiding faces provided on the rings. The spacer comprises opposite inner and outer parts | 12-03-2015 |
| 20160131183 | SPACER DEVICE, TOROIDAL ROLLER BEARING & METHOD - A spacer device for roller elements of a toroidal roller bearing includes an inner ring and an outer ring. The toroidal roller bearing allows for axial and angular displacement between the inner and outer rings. The spacer device comprises a first roller element-contacting surface and a second roller element-contacting surface on opposite sides thereof. First and second roller-contacting surfaces are arranged to separate two adjacent roller elements in a tangential direction of the toroidal roller bearing when the spacer device is in use. Each of the first and second roller element-contacting surfaces has a concave shape adapted to conform to respective convex contacting surfaces of the roller elements. The spacer device comprises end members that have projections that extend outwards from first and second roller-contacting surfaces and which are arranged to extend at least partly over the ends of two adjacent roller elements when the spacer device is in use. | 05-12-2016 |
| 20160131184 | SPACER DEVICE, TOROIDAL ROLLER BEARING & METHOD - A spacer device for roller elements of a toroidal roller bearing includes an inner ring with an inner ring raceway and an outer ring with an outer ring raceway. The toroidal roller bearing allows for axial and angular displacement between the inner ring and the outer ring. The spacer device comprises at least one centering element that is arranged to extend in between adjacent roller elements in a longitudinal direction of the roller elements when the spacer device is in use. The at least one centering element is arranged to make contact with at least one of one point or a region of one of the inner ring raceway or the outer ring raceway when the spacer device is in use, whereby the spacer device is centered on the one of the inner ring raceway or the outer ring raceway. | 05-12-2016 |
