Abstract
O-rings are machine installed in retention grooves cut into a cylindrical part through the use of a size matched cylindrical mandrel that moves in piston fashion within a guide cylinder. A feed ramp and loading slide stretch each O-ring over the end of the mandrel, which is then abutted with and pushed down by the part into the cylinder. The O-ring is thereby rolled off of the mandrel by the edge of the cylinder and onto the part until it snaps into the retention groove.
