Perma Automatic Lubricant Injector
The Perma injector consists of a cylinder containing a
pressure generator and a piston which, in response to
the pressure generator, pushes the pre-packed lubricant
into the bearing.
The pressure generator is a rubber bladder containing
an electrolytic solution and a sealed plastic tube
containing a galvanic strip of specially treated metal.
When the Perma injector is installed, the plastic tube is
broken by the activating screw, exposing the galvanic
strip to the electrolytic solution. This results in an
electro-chemical reaction within the bladder which
produces a gas. As the bladder expands with the
production of the gas, it pushes against the piston
which in turn pushes the lubricant out of the injector
and into the bearing. When all of the lubricant has
been expelled into the bearing over the life of the
particular Perma unit installed, it is thrown away and a
similar unit installed and activated. The Perma unit is
non-refillable.

Visual Safety Check
As the Perma nears the end of its effective life, an
internal metal ring becomes clearly visible through the
clear plastic cap, indicating that the Perma should be
replaced.

Figure 9
A decal similar to the one shown in Figure 9 is
attached to the UW control module. The decal
indicates the required replacement date for the
automatic injectors originally supplied on your
machine. The replacement date is punched out on the
decal. On the example shown above, the replacement
date is during the third month of 1985.
