A railcar bogie axle box suspension axle beam includes an end portion d at a tip end, a tubular portion at the end portion and being open at both car width direction sides. The tubular portion includes: a first semi-tubular portion integrally formed with a main body portion; a second semi-tubular portion brought into contact with the first semi-tubular portion from one side in the car longitudinal direction; and a bolt fastening the second semi-tubular portion to the first. The first semi-tubular portion includes: a flat opposing surface contacting the second semi-tubular portion; and a hole into which the bolt is inserted. The second semi-tubular portion includes: a flat opposing surface contacting with the first semi-tubular portion surface; a flat machining reference surface formed at an opposite side of the opposing surface; and a hole extending in a direction perpendicular to the opposing surface, the bolt inserted into the hole.

An axle box for a railway vehicle including a casing provided with a through-bore extending along a median axis, a journal unit accommodated in the bore, a front cover, and a rear cover. At least one part of the front and rear cylindrical parts of the front and rear covers, respectively, having a threaded exterior surface screwed into a tapped portion of the central bore of the casing.

Railcar adapter for connecting a railcar body to a bearing providing an adapter body having two lateral channels each axially delimited by a pair of opposed lugs and a lateral surface perpendicular to the opposed lugs, each lateral channel being adapted to cooperate with the railcar body. The railcar adapter further provides swivelling means allowing swivelling of the railcar adapter relative to the railcar body.

The invention provides a railway condition monitoring sensor device attached to a railway bearing of a railway vehicle including at least one vibration sensor; means for detecting movement of the railway vehicle; a control unit for processing at least the signals obtained by the vibration sensor to determine a health parameter indicating the bearings state of health. The control unit triggers measurements based on at least one predetermined condition; and a wireless communication device for communicating the health parameter to a monitoring and control server. The control unit configured to be operated in an energy-saving sleep mode and in at an activated mode. The control unit is configured to switch from the sleep mode to the activated mode upon detecting that a predetermined set of conditions is met. The predetermined set of conditions includes the condition that the means for detecting the movement detects that the railway vehicle is moving.

A railcar adapter for radially connecting a railcar body to a bearing, and providing an adapter body. The railcar adapter includes two channel elements having each a pair of opposed lugs and a lateral guiding surface perpendicular to the opposed lugs so as to form lateral channels adapted to cooperate with the railcar body. The lateral channel elements are mounted in transverse grooves provided to transverse surfaces of the adapter body.

A bearing assembly comprising a bearing cup having two ends, with a pair of outer raceways formed one adjacent each end of the bearing cup. A pair of bearing cones form a pair of inner raceways. Two rows of tapered roller bearings with each row received between one inner raceway and one outer raceway. A pair of wear rings are provided, each having a first axially inwardly directed end in engagement with an outwardly directed end of a bearing cone. A pair of seals each having a first end fitted into one into one of the bearing cup cylindrical counterbores. Each seal has a second end including a resilient element to form a seal with one of the wear rings. A second end of each wear ring is received in a cylindrical counterbore in each annular backing ring. A circular shroud is located radially outer and adjacent to one seal.

The invention relates to a railway axlebox bearing assembly including a radially outer mounting surface configured to be mounted so as to face a radially inner mounting surface of an axlebox housing. It is proposed to further provide the assembly with least two spacer elements configured to be mounted between the radially outer mounting surface and the mounting surface of an axlebox housing.
