The ring stretcher “Universal 2000” is characterized by a 6 spline mandrel made in
bronze which avoid wear and jamming on the expansion conical rod. Besides,
thanks to the locking plate guiding the cone, the ring widening is absolutely even
The disk used to narrow the rings is provided with 16 conical holes with a
particularly smooth surface and entirely protected against rust by chrome coating,
as well as all other exposed parts of the machine.
