Slim pantograph jack with bearing spacer

摘要

A pantograph jack includes a base, a load rest, first and second lower arms each pivotably coupled at a first end to the base, and first and second upper arms each pivotably coupled at a first end to the load rest. Second ends of the first lower and upper arms are pivotably coupled at a first joint. Second ends of the second lower and upper arms are pivotably coupled at a second joint. A screw extends between the joints and operably moves the joints toward and away from each other upon rotation of the screw to raise and lower the load rest. A bearing spacer includes a flange forming a bearing engagement surface at a first end and a second end engaging the second joint. The drive screw has an abutment facing the bearing engagement surface. A bearing is located between the bearing engagement surface and the abutment.
