Backstop (R)
The anti-rotation backstop only allows rotation in
one direction. NORD’s backstop is installed internally
to the reducer and will hold the speed reducer’s rated
torque.
The 90 series bevels can be built with internal back-
stops. Additionally, units with W-input cylinders and
NORD motors frame size 80 and larger offer integral
backstops.
The direction of rotation is required when ordering a
unit with a backstop. Please reference the drawings
below.
?
Specify the direction of allowable
rotation when ordering.
Clockwise (CW) or Counter-Clockwise (CCW)
WARNING
When a gear unit or a motor includes a backstop, check
the motor and gear direction of rotations before starting
the system. Attempting to operate the unit in the wrong
direction may cause damage.
Clincher with B14 on motor side
As an option, Clincher TM reducers can be supplied with
an additional B14 fl ange on the motor side.
Oil Expansion Chamber (OA)
Oil expansion chambers are available
for most reducers. These chambers
allow for expansion of the oil-air mix in
the reducer that can occur during oper-
ation. This expansion chamber is simi-
lar to a car radiator over-fl ow chamber.
See page 45 for additional details and
selection guidelines.
Oil Reservoir Tank (OT)
The oil reservoir tank allows the reducer housing to be
completely fi lled with oil. The tank always contains
oil and is above the reducer oil sump, which allows
the reducer to be completely fi lled with oil. See page
46 for additional details and selection guidelines.
Oil Cooler (OC)
The cooler is an external device to cool the reducer’s
lubricating oil. In some applications it is necessary to
provide oil cooling to ensure the oils maximum oper-
ating temperature is not exceeded. See page 4
1 for
additional details and selection guidelines.
Water Cooling Cover (WC)
A water cooling plate is an alterative to an oil cooler
in some situations. The larger Clincher™ and Bevel
units can be fi tted with a water cooling plate to cool
the reducer’s oil reservoir. See page 4
0 for additional
details and selection guidelines.
