The Shafer Tri-Roller swaging tool is simple
to set-up and operate. A small hand-fed drill
press is recommended to install grooved bearings
into their housings.
Begin by inserting the roller fixture into
the drill press spindle and setting the spindle
speed to approximately 100RPM (higher speeds
can be used when the operator gains more
proficiency). Note: Guide bars or fixtures may
be used to accurately position the locating
fixture for repeated operations.
Next, position the housing and bearing on
the locating fixture and guide the pilot of the
roller fixture into the bearing bore.
Utilize light pressure during initial
revolutions to allow the rollers to center in
the bearing groove.
Follow this with more arm pressure until
the bearing lip is swaged (approximately 5
seconds).
Turn the bearing and housing over and
repeat the process.
