SINEBAR
Accurate fit between a tapered bore bearing and its journal
is critical if a bearing is to reach maximum life. Certified
NSK Sine Bar Gages are designed to provide an accurate
and easy method to measure a journal’s taper, size,
contact area and out of roundness.
A complete sine bar gage set for measurement of either
1:12 or 1:30 shaft tapered journals consists of:
• 3,4,5.5,7,10 and 14 inch long sine bar gages
• 2 sine bar blocks
• a strap
• calibration reports
• wooden box for transportation
• 2 clamps
• journal details charts
• instructions for use
NSK sine bars are coated with a special anti-rusting
treatment, come with easy to read laminated instructions
and are available individually, in combination or as
complete sets. They are lightweight, easy to handle and a
cost effective way to ensure maximum bearing life.

Induction heaters are a preferred and much safer
method of heating a bearing than using a flame or oil bath.
Bearing heaters produce strong alternating magnetic fields
that induce eddy currents in the metals. The currents
cause rapid and efficient heating of the component and
the low voltage output eliminates any hazards due to
shocks or sparks.
Bearing heaters from NSK are a fast, safe and efficient way
to mount straight bore bearings onto shafts. They provide
uniform inner ring heating that helps to reduce bearing
mounting, time and cost. With automatic temperature and
demagnetizing control features, a light and compact design,
and the versatility to heat many different bearing sizes and
types of components, NSK bearing heaters are a must have
for maintenance professionals.

Pullers, pushers, straighteners and tri-section press
plates are useful in the quick, easy and safe
installation and removal of bearings, rings, pulleys
and gears. The use of these tools is helpful in
protecting the shaft, bearings and surrounding
equipment from damage. They also help reduce
the potential for bodily harm to the operator.
NSK’s family of pullers, pushers, straighteners
and tri-section press plates come in a full range
of sizes and come individually or in kits
specifically matched to customer needs.
NSK offers a hydraulic pusher, puller
and tri-section press plate in a single heavy
duty case making transportation and storage
more convenient as well as reducing the
possibility of lost parts. Pullers are available
in non-interchangeable standard and high
capacity designs. The high capacity design
includes a high pressure cylinder and cobra jaw.
Hydraulic pullers and pushers from NSK
incorporate course threads which make it easier
and quicker to assemble than competitive

Hydraulic nuts from NSK utilize an axial drive-up method
to ensure the accurate and quick installation of tapered
Nut
bore bearings. The axial drive-up method ensures that the
internal clearance and interference fit is correct by
monitoring the movement of the piston, and thus the
bearing's inner ring, in relation to the hydraulic nut. This
method minimizes the need to continually check the
clearance reduction with feeler gages.
The benefit of NSK’s patented axial drive-up method is
that it does not require the use of a dial indicator or charts.
Competitive axial drive-up systems require a special dial
indicator and the use of printed charts, which not only add
to cost but can also be difficult to read.
NSK hydraulic nuts are coated with Armoloy, a special
permanent anti-rusting layer, making them much more
durable than other offerings. They also use NPT ports
so replacement fittings are inexpensive and easy to obtain.
Cranking handles come in standard diameter rod sizes so
replacements can be made from standard stock instead
of having to buy specialized sizes as is common with
competitive offerings. Larger sizes are made with
tapped holes for eye bolts for easy lifting.
Hydraulic nuts come complete with jack
out bolts that are very useful in making the
replacement of seals quick and easy. A full
size range is available and all hydraulic
nut kits come in a secure
carrying case.

NSK Hydraulic Nuts
There are three different ways to use Hydraulic Nuts. Below are the three methods. Contact NSK if you have any questions.

Cb = Bench Clearance
Cm = Mounted Clearance
Cr = Clearance Reduction
Da

Using Axial Displacement Pin:
Piston is ready to move the bearing by pushing against the inner ring.

After Mounting
Da = Min. Axial Displacement
Using Axial Displacement Pin:
Piston has moved the bearing the minimum axial displacement.
The Axial Displacement pin is flush with the back of the nut.

Straight edge method
Axial Displacement Pin
Wrench
Wrench
Back of Nut
Using Straight Edge:
Placing a straight edge such as a wrench will show a gap.
3
Dial indicator method
Magnetic Base
Dial Indicator
Using Dial Indicator:
Place a dial indicator on the back of the axial displacement pin.
No Gap
Axial Displacement Pin
Using Straight Edge:
The gap has disappeared indicating the bearing has moved
the minimal axial displacement.

Dial indicator method
Magnetic Base
Dial Indicator
Using Dial Indicator:
Watch the gage to determine the axial displacement of the bearing.

LOCKNUT P/N
23-30
Spanner wrenches are a simple and inexpensive means
of installing small size tapered bore bearings onto shafts
and adapter sleeves. Because they clamp onto the slot in
a locknut, they do not cause damage to the locknut which
frequently occurs when using a hammer and keystock.
NSK standard spanner wrenches are made from 1/4”
(7mm) thick plates. The heads of impact spanner wrenches
are made of forged steel, which is welded to a strong
alloyed steel handle covered by easy grip rubber.
NSK impact-spanner wrenches are heavy duty and can
withstand the impact force of a hammer. All wrenches come
with a convenient hole for ease of storage or hanging.
METRIC
* The largest standard spanner wrench is HN 22.
