Synchronized spacer for linear guides has ball bearings mounted along it and moves in closed path inside rail, guide pieces being mounted on either end with curved surface which are smaller than rollers but bigger than spacer linking them

摘要

The synchronized spacer (20) has rollers (40) mounted along it and moves in a closed path inside a rail (51). Guide pieces (30) are mounted on either end with a curved outer surface (31) which contacts the inside of the rail. These are smaller than the rollers but bigger than the spacer linking them.
