INTRODUCTION
Foot Mounted with B5 Flange (XF)
NORD can supply some foot mounted reducers with
a B5 fl ange as well. These type XF reducers are de-
signed to be foot and not fl ange mounted. The B5
fl ange is normally used to mount auxiliary equipment
to the speed reducer. If the B5 fl ange is going to be
used to mount the reducer, additional support will
normally be required.
Foot mounted with B14 Face Flange (XZ)
NORD can supply some foot mounted reducers with
a B14 face fl ange as well. These type XZ reducers are
designed to be foot and not fl ange mounted. The
B14 face fl ange is normally used to mount auxilia-
ry equipment to the speed reducer. If the B14 face
fl ange is going to be use to mount the reducer, ad-
ditional support will normally be required.
Shaft Options
Solid Shaft (Blank or V)
NORD’s standard keyed solid shafts
include a centered threaded hole.
Shafts are available as inch or metric
versions. The standard shaft mate-
rial is 1045 or 4140 or equivalent.
Double Solid Shaft (L)
The standard solid shaft end is
projected out both sides of the
speed reducer. This option is com-
monly used to transfer torque
out of both sides of the reducer
or to mount a speed-monitoring
device such as an encoder on one
of the shaft ends. If you need the
keyways to be alligned you must
specify with NORD upon ordering
Keyed Hollow Shaft (A)
NORD’s standard keyed hollow shafts
are made from SAE 1045 high carbon
steel. They feature standard keyway
dimensions and are available both
inch and metric designs. Many NORD
reducers offer a variety of hollow
shaft diameters.
Shrink Disc (S) (SH)
The shrink disc relies on the prov-
en wedge principle to create a
keyless, mechanical interference
fi
t by converting locking screw
tension into radial contact pres-
sure on shaft and hub in effect
“shrinking” it on to the customer
shaft. Shrink discs result in a zero
backlash mechanical interference fi t that can ac-
commodate high torque unlike other mounting
technologies and will never wear or pound out, even
for high cycle fl uctuating and reversing loads.
Other shrink disc advantages include:
• Elimination of fretting corrosion associated with
key
connections.
• Generous clearance for easy mounting & dismounting.
• Allow for larger bores sizes compared to keyed
hollow
shafts.
• For more information see page 72
Heavy Duty Shrink Disc (VS)
NORD heavy duty shrink discs offer increased clamp-
ing force and safety factor for severe applications.
Special Shafts & Shaft Materials
Stainless Steel Output Shaft (SM5)
Output shafts made from stainless steel are available
and are frequently used in food, pharmaceutical, and
washdown applications. In some cases solid input
shafts can also be provided in stainless.
Special Solid Shaft (SWV)
Special solid shaft diameters and lengths can be pro-
vided for a nominal price adder. Special features are
also available including keyless shafts, cross drilled
shafts or special threaded taps. Different shaft mate-
rials are also available. NORD has in-house drafting
design and machining departments so we can provide
special requirements in short lead times. Specify your
shaft requirements and NORD will verify the design
feasibility.
