Couplings for the NEMA and IEC Adapters
Depending on the size of the input adapter to the gearbox, NORD Gear supplies two styles of couplings - BoWex
“
(gear tooth) and Rotex
“
(jaw) couplings.

Couplings
NORD C-face adapter input shafts have a machined spline on the end. NORD incorporates two styles of BoWex
“
couplings, the “J” and “M”
styles. The “J” style is a one-piece coupling with a metal hub and nylon spline. The “M” style is a two-piece coupling – the metal hub and a
nylon sleeve. Nylon and steel components allow them to operate in high ambient temperatures without lubrication or maintenance.

Nylon sleeves resist dirt, moisture, most chemicals and petroleum products

Couplings
The cast iron jaw type couplings have an integral urethane “spider” that
provides smooth transmission of the motor torque. A set screw on the
coupling prohibits axial movement along the motor shaft.
