Abstract: A through pin assembly for securing an axle into a pair of mounting cheeks and to stabilize a machine member is disclosed. The pin assembly has an axle having a pair of end members formed on each end of the axle. A channel is formed through the axle and runs a length of the axle. The channel consists of a threaded area of the channel at the first end for use when removing the assembly; a hexagon, octagon or otherwise shaped area at the second end to interlock with the threaded part of the locking end member; two grooves in the channel, one at each end, as a seat for gaskets to seal off a grease or oil chamber for distribution to the bearing. A bearing is mounted on a central section of the axle. A pair of expansion sleeves is provided wherein one of the pair of expansion sleeves is positioned over each of the end member of the axle. A locking device is inserted into the channel.

Abstract: A device for an anchorage of an axle at each of its ends, preferably in a pair of fixing lugs formed with through holes for the axle. The device is characterised in that at each end of the axle there is at least one plane chamfer. The chamfer forms an angle a with the longitudinal axis of the axle and is connected to the outer surface of the axle, leaving a cylindrical axle section between the plane chamfers. The device at each plane chamfer includes a body, with a first section having an angle substantially similar to the plane chamfered part of each axle end, together with a second section, extending axially, and a segmental-shaped end, which along its curve has a flange that is directed radially outwards past the periphery of the axle. The is designed to act as a wedge with points directed towards the cylindrical centre section. An anchor element having a movement can be imparted to the body in an axial direction towards the cylindrical section, thereby producing an anchorage of the axle in each hole.
