the rollers. The cage thus acts as. a seal pre
venting the lubricant from being forced betweenl
the face 2 of the base and the roller bearing.
The lower face of the head l is shaped to ensure 25
contact with the rim of the central opening in
thebody of a bearing regardless of whether or
not the operator positions the plunger and guide
in an exactly vertical position over the bearing.
By means of the bearing packer described, it is [email protected]
possible to readily force lubricant of stiif con
sistency in between the rollers of the bearing in
an expeditious manner. It is more economical
