Abstract:
1. A spindle and bearing combination for use in a drug delivery device comprising, a) a rotatable spindle having a distal end; and b) a disk-shaped bearing configured to abut a proximal face of a non-rotatable piston in a medicament container, where the disk-shaped bearing has a first connection and a second connection to the distal end of the spindle, where the first connection comprises a web that fixedly attaches the disk-shaped bearing to the spindle to prevent independent movement of the disk-shaped bearing relative to the spindle and where the second connection is created and replaces the first connection when the web is sheared such that the spindle is rotatably connected to the disk-shaped bearing and the distal end of the spindle is retained within the disk-shaped bearing by a pair of cooperating web shears formed from the sheared web.
