| 20090123099 | Bearing Assembly With a Seal-Forming Bore Clip - A bearing assembly (A | 05-14-2009 |
| 20120082407 | Railway car bearing seal spacer assembly - A bearing assembly is provided having a roller bearing with two cones defining an inner raceway fitted around the journal portion of an axle. A cup defines an outer raceway that combines with the inner raceway to receive roller elements. A spacer separates the cones, and a spacer support is provided to position and support the spacer. | 04-05-2012 |
| 20130230265 | ROLLER BEARING BACKING RING ASSEMBLY - A novel assembly for a railcar axle bearing is presented. The assembly includes a backing ring affixed to the fillet of the journal of an axle and a locking ring for further affixing the backing ring the journal. The locking ring has an inboard end affixed to the dust guard of the axle and an outboard end for engaging the backing ring. The looking ring may include a resilient sealing ring. | 09-05-2013 |
| 20140241655 | STABILIZED BACKING RING AND STABILIZING RING THEREFOR - An axle (A) has a journal ( | 08-28-2014 |
| 20140301685 | BEARING DEVICE FOR AXLE OF RAILWAY VEHICLE - An axle bearing device includes an inner ring fixed to an axle of a railway vehicle, an outer ring fixed to a journal box of the railway vehicle, and double row tapered rollers arranged between raceway surfaces of the inner ring and raceway surfaces of the outer ring. An opening portion between the inner ring and the outer ring is sealed by a labyrinth seal including at least one axial labyrinth extending in an axial direction and at least one radial labyrinth extending in a radial direction. At least one of the at least one axial labyrinth and the at least one radial labyrinth which form the labyrinth seal is formed between an outer-ring-side sealing member mounted to the outer ring and the inner ring or between the outer-ring-side sealing member mounted to the outer ring and an inner-ring-side sealing member mounted to the inner ring. | 10-09-2014 |
| 20150078693 | BLOCKING END CAP FOR A ROLLING BEARING AND SUPPORTING DEVICE FOR A RAILWAY AXLE EQUIPPED THEREWITH - A blocking end cap for a rolling bearing in a railway axle box of a supporting device for a railway axle is provided. The cap is shaped as a concave disc delimited by an annular side wall having a symmetry axis (A), a bottom wall arranged transversely to the symmetry axis (A), and an elbow-shaped, annular joining portion, connecting the bottom wall to the side wall. The thickness of the bottom wall measured in a direction parallel to the symmetry axis (A) is continuously variable in the radial direction between a maximum (S1) situated at the symmetry axis (A) and a minimum (S2) arranged at a radially outer edge of the cap defined by the side wall. | 03-19-2015 |
| 20160061266 | LOW-FRICTION DYNAMIC SEAL - A sealing arrangement, for sealing of a radial gap between relatively rotatable inner and out components, whereby the inner component is rotational about an axis of rotation and the outer component is coaxially arranged around the inner component. The sealing arrangement comprises: a dynamic seal part mountable to the inner component; a static seal part mountable to the outer component; and first and second labyrinth seals, each being formed by a gap between at least one set of opposing surfaces on the static and dynamic seal parts, and a lip seal arranged radially between the first and second labyrinth seal. The lip seal comprises a sealing lip connected to the dynamic seal part and bears against a radially oriented counterface on the static seal part. The sealing lip has a longitudinal extension in a radial cross section that extends towards the rotation axis at an angle between 10° and 80°. | 03-03-2016 |
| 20160101791 | BACKING RING FOR RAILCAR AXLE - A backing ring assembly for a railcar axle is provided. According to various aspects, the backing ring assembly may include a main body and a ring. The main body may include an inner surface configured to abut a fillet of a railcar axle and a receiving element on an inboard radial face of the main body. The ring may be engaged in the receiving element and may be configured to protrude over a cylindrical surface of a shoulder on the railcar axle. The ring may include an inner face having a recess and a generally flat outer face. | 04-14-2016 |
