Single-Side Adaptor Hub Type (A-Hub Type) / Unit Spacer Type (U-Type) Couplings
The NEH Series Adaptor Hub Type coupling provides a larger bore diameter than the standard hub. With the Unit Spacer Type, the spacer unit can
be mounted or removed without the need to disassemble the disk connecting section.
