1. 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.
 
11. 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 self-lubricating liner disposed in the bore between the inside housing surface and the exterior shaft surface, the self-lubricating liner having an inside liner surface that is in sliding engagement with the exterior shaft surface of the shaft and the self-lubricating liner having an exterior liner surface; and
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, wherein the exterior liner surface is secured to the inside bushing surface, wherein the bushing comprises a groove extending axially along the inside bushing surface and radially outward towards the exterior bushing surface, the groove radially terminating between the inside bushing surface and the exterior bushing surface.
 
15. 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;
two bushings disposed in the bore, each of the two bushings having an exterior bushing surface secured to the inside housing surface such that the two bushings are spaced from one another, and each of the two bushings having an inside bushing surface; and
a self-lubricating liner disposed in each of the two bushings, each self-lubricating liner 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 of one of the two bushings, wherein the two bushings each comprise a groove extending axially along the inside bushing surface and radially outward towards the exterior bushing surface, the groove radially terminating between the inside bushing surface and the exterior bushing surface.
