My invention relates to a journal stop for railroad car
axles and has for one object to provide a stop which may
be applied to the outboard end of the journal after the

in place thereon by radial tabs 20 extending on opposite
sides from the armor ring and bent down into contact
with the sides of the cushion ring.
