Abstract
A linear guide mechanism includes a housing having an inside housing surface that defines a bore extending through the housing coaxial with a longitudinal axis. A shaft is disposed at least partially in the bore and is reciprocatably and linearly moveable in the bore along the longitudinal axis. The shaft has an exterior shaft surface. A self-lubricating liner is disposed in the bore between the inside housing surface and the exterior shaft surface. The self-lubricating liner has an inside liner surface that is in sliding engagement with the exterior shaft surface of the shaft. The self-lubricating liner has an exterior liner surface.

A linear guide mechanism for a reciprocating container forming apparatus, the linear guide mechanism comprising:
- a housing having an inside housing surface that defines a bore extending through the housing coaxial with a longitudinal axis;
- a shaft disposed at least partially in the bore and being reciprocatably and linearly moveable in the bore along the longitudinal axis, the shaft having an exterior shaft surface;
- a bushing disposed in the bore, the bushing having an exterior bushing surface and an inside bushing surface, the exterior bushing surface being secured to the inside housing surface;
- and
- two self-lubricating liners each having an inside liner surface that is in sliding engagement with the exterior shaft surface of the shaft and an exterior liner surface that is secured to the inside bushing surface such that the two self-lubricating liners are spaced apart from one another by the bushing.
