SECTION I
Understanding the Taber Abraser
INTRODUCTION
The Taber Rotary Platform Abraser Model 5135
and 5155 are durable, precision built test
instruments designed to evaluate the resistance
of surfaces to rubbing abrasion. Their field of
application is varied and includes tests of solid
materials, coated surfaces (paint, lacquer,
electroplated), plastics, textiles (ranging from
sheer silks to heavy upholstery), metals, leather,
rubber, linoleum, plus many others. In the
hands of a competent research technician, the
Abraser is capable of performing reproducible
tests, accurate within the variations of quality
inherent in the material itself.
axis of the sample. Figure 3 diagrams the
relative positions of the sample and abrading
wheels and the direction of their rotation.
One abrading wheel rubs the specimen outward
toward the periphery and the other, inward
toward the center. The resulting abrasion marks
(Figure 4) form a pattern of crossed arcs over
an area of approximately 30 cm
satisfactory for rating most materials.

),
PRODUCT DESCRIPTION
Characteristic rub-wear action of the Abraser is
produced by the contact of a test sample turning
on a vertical axis, against the sliding rotation of
two abrading wheels. The wheels are driven by
Figure 3
the sample in opposite directions about a
horizontal axis displaced tangentially from the
Figure 4
An exclusive and important feature of the 5135
and 5155 Abrasers is that the wheels traverse a
complete circle on the specimen surface,
revealing abrasion resistance at all angles
relative to the weave or grain of the material.
PRODUCT FEATURES
The Model 5135 and 5155 Abrasers have many
improved features compared to earlier versions
of the Taber Rotary Platform Abraser. These
are identified with an asterisk (*).
Operator Interface / Display*
The operator interface is an easy to use
membrane panel with tactile feel buttons and a
4-line digital display. Simple on-screen
instructions allow the operator to change the test
parameters and are accessed via the MENU
button. The following test parameters are
shown on the screen: test mode, test duration,
test cycles (completed or remaining), turntable
speed, and vacuum suction level (%).
60 / 72 RPM Turntable Rotation Speed*
Models 5135 and 5155 offer both 60 rpm and 72
rpm turntable rotation speed. This enables the
operator to select the speed referenced in the
test standard.
NOTE: The turntable speed on previous versions of
the Taber Abraser was dependent on the electrical
line frequency. At 60Hz, the turntable speed was 72
rpm and at 50Hz the turntable speed was 60 rpm.
Preset Cycles Buttons*
The operator interface includes four commonly
used preset cycles buttons. This enables the
operator to automatically program 100, 500,
1000 or 2500 test cycles. The buttons may also
be used to “add to” the cycle count by the
corresponding incremental values.
Abrading Head Assemblies
Models 5135 and 5155 have independent
abrading arms of forged aluminum alloy that
pivot on ball bearings. The forward end of the
arm has a quick release wheel-mounting hub to
which the abrading wheel is mounted. The arms
are precision balanced to ensure exacting
results. Each arm applies 250 grams force
against the specimen with the wheel mounting
assembly in place (exclusive of the mass of the
wheels itself).
The outer end of the abrading head assembly
allows the auxiliary weight to be mounted
concentric with the abrading wheel. A stud on
the rear end of the abrading arm may be used to
carry a counterweight when it is desired to
reduce the wheel load to less than 250 grams
when testing delicate materials. It may also be
used to hold an abrading wheel as a
counterweight to compensate for the mass of
the working wheel.
Quick Release Mounting Hub*
An expanding collet hub design with push-button
operation permits quick wheel mounting, without
the need of a locking nut. A spring loaded,
beveled retaining nut provides a positive locking
force on the hub retaining lip making certain the
wheels remain securely fastened until
disengaged. The increased clearance results in
a larger viewing area of the test specimen.
4 5135 / 5155 Operating Instructions ver 1.1
Auxiliary Weights
Model 5135 has two pairs of precision stainless
steel weights of 250 grams and 750 grams
furnished with the testing set. In addition to the
mass of the abrading arm itself (250 grams) they
provide standard wheel loads of 500 and 1000
grams. Figures 6 – 9 show abrasers with
different loads applied (per wheel).
Available counterweights reduce the 250 gram
load to 125 grams or 75 grams (Figure 9).
Counterweights may be used in conjunction with
the standard weights to further expand the range
of wheel loads. To offset the weight of the
working wheels, wheels may be placed on the
counterweight-mounting studs.
NOTE: For simplicity, each weight is marked with the
total load that will be exerted on the wheel.
Figure 9
Vacuum System
Models 5135 and 5155 include a vacuum unit
with a heavy-duty motor and life-lubricated
sealed bearings. With the vacuum power
connection plugged into the rear of the abraser
housing, the vacuum will be automatically turned
on when a test is commenced and shut off at the
end of the test cycles. A flexible rubber suction
hose connects it to the Abraser.
A vacuum pick-up nozzle is hinged to an
adjustable mount at the rear of the housing. The
height above the specimen is set by raising or
lowering the precision vacuum adjustment.
Figure 6
Figure 7
Precision Vacuum Nozzle Adjustment*
The height of the vacuum pickup nozzle is
adjusted by turning a knob. Each turn
represents 1.27 mm (0.05 inch) height adjustment,
making it significantly easier to set the proper
distance between the nozzle and specimen
surface. Located on the top of the instrument
next to the vacuum nozzle, the knob is easily
accessible.
Specimen Holder
The Model E100-125 specimen holder
accommodates most materials less than 6.35
(0.25 inch) thick with a 6.35 mm (0.25 inch)
mm
center hole. Rigid, flat specimens are secured
using the clamp plate and nut. For flexible
specimens, the E100-101 clamp ring is provided
in conjunction with the clamp plate and nut. An
S-19 rubber pad prevents specimens from
slipping during the test.
Specimen Holder Drive Shaft
The drive shaft for the specimen holder projects
vertically through the motor well in the Abraser
housing. Interchangeable specimen holders are
mounted to this shaft.
Figure 8

Accessory Receptacles
The Model 5135 and 5155 Abraser permit
control of the vacuum unit and an accessory
instrument (wheel refacer or grit feeder) from the
main unit. The electrical receptacles are
integrated in the rear of the housing and marked
accordingly (Figure 10). The use of the
electrical receptacles is restricted to the
specified equipment.

SPECIMEN SIZE
The width of the wear path is 12.7 mm (0.5 inch),
and located 31.75 mm
of the specimen. The size of the specimen may
vary depending on the material being evaluated.
For most rigid materials, a sample approximately
100 mm
(4.0 inch) square is recommended.
Flexible specimens are typically circular and
require the use of the clamp ring. If a mounting
card is used, the specimen should be
approximately 108 mm
no mounting card is used, a 135 mm
specimen is required such that the clamp ring
will grip the overlapped material.
If the specimen is less than the suggested size,
it is possible to position two or more specimens
on a mounting card to meet the size
requirement. If the edges are not flush together
or if the samples are of different thickness, the
edges may wear at a different rate than the rest
of the specimen.
The standard material thickness that can be
evaluated with the Taber Rotary Platform
Abraser is 6.35 mm
greater than 6.35 mm (0.25 inch) but less than
12.7 mm
(0.5 inch), the S-21 extension nut may
be used. Specimens with a thickness greater
than 12.7 mm
(0.5 inch) can be tested using the

Mounting Sheets (S-37 and S-37-1)
These 108 mm (4.25 inch) sheets are coated on
both sides with pressure sensitive adhesive
overlaid with protective paper that is peeled off
just prior to use. Thinner than the S-36 and S36-1, mounting sheets are used to provide a
non-slip attachment of the specimen to the
surface of the turntable and are especially useful
for materials difficult to drill a center hole (such
as glass or ceramics). Mounting sheets are
available as square (S-37) or round (S-37-1),
and have a test record printed on both sides
enabling them to be used as a mounting card.
SPECIMEN MOUNTING OPTIONS
To expand the versatility of the Taber Abraser,
mounting options and interchangeable specimen
tables are available to evaluate materials not
easily tested with the standard configuration. All
tables are engineered with a ball plunger and
drive pin spring clutch that locks the table onto
the motor shaft. This prevents the table from
shifting during a test, but allows for it to be easily
removed for specimen inspection or to clean the
motor shaft cavity. To gain access to the
specimen holder, lift the suction nozzle on its
hinge and raise the abrading arms up and back
beyond their balance point.
Mounting Cards (S-36 and S-36-1)
These 108 mm (4.25 inch) rigid cards are coated
on one side with pressure sensitive adhesive.
Designed to hold textile and other flexible test
specimens tightly to the mounting surface, they
prevent wrinkling while undergoing testing. A
test record form is printed on the backside of the
card for permanent record. Mounting cards are
available as square (S-36) or round (S-36-1).

Specimen Holder (E100-125)
The specimen table equipped with the Abraser
(E100-125) has been designed to accommodate
most materials less than 6.35 mm
thick. Unless optional accessories are utilized, a
6.35 mm (0.25 inch) center hole must be punched
or drilled in the specimen so it can be securely
fastened to the threaded center post.
To secure rigid materials, use the clamp plate
and nut. For flexible materials, also use the
supplied E100-101 specimen clamp ring. A 108
mm
(4.25 inch) diameter rubber pad (S-19) is
provided to ensure a non-slip surface.

Specimen Holder with Ring Clamp
(E140-14)
Rigid specimens that are slightly warped and
less than 6.35 mm
either dry or wet tested using the E140-14 Ring
Clamp Holder. Eight (8) screws are spaced
evenly on the clamp plate, and when tightened,
will correct for slightly warped conditions. This
holder can be furnished with (E140-14-S) or
without (E-140-14-NS) a center clamping screw.
Specimens should be 137 mm
diameter with a 6.35 mm
(0.25 inch) in thickness can be

Textile Specimen Holder – Tensioning
Type (E140-15)
Textile Holder – Tensioning Type for Wet
or Dry Testing (E140-18)
Similar to the standard specimen holder, the
E140-15 Tensioning Textile Specimen Holder
has a slightly raised wear track. This gives
textile and other flexible specimens additional
tension when the clamp ring is drawn down over
the edge of the holder and the clamp plate is
tightened in the center recess. Requires a 134
mm (5.25 inch) diameter specimen with a 6.35 mm
(0.25 inch) center hole. This holder is not
recommended for use with rigid specimens or
with mounting cards.
NOTE: For proper mounting, place the specimen on
the holder and draw it taut with the clamp ring.
Tighten the ring, and then mount the clamp plate.
The E140-18 holder is designed to give an initial
stretch to woven fabrics so that they may be
tested while moist with minimum tendency to
wrinkle. A raised wear track provides additional
tension on the specimen, while a 9.53 mm

NOTE: For proper mounting, place the specimen on
the holder, position the clamp ring and mark the holes.
Where each hole was marked, make a small cut such
that the screws may be aligned and mounted to the
holder. Partially tighten down the clamp ring. Draw
the fabric taut under the ring, tighten the screws, and
trim off excess material around the edge. Tighten the
clamp plate.
NOTE: When the fabric specimen is to be tested at
specific moisture content it must be conditioned to that
content before it is mounted on the holder.

Drive Pin Type Holder (E140-19)
Threaded Ring Specimen Holder (E140-21)
The E140-19 Drive Pin Holder is intended for
rigid, square specimens that do not have a
center-mounting hole. The specimen is adhered
to the holder with S-37 or S-37-1 mounting
sheets and opposing driving pins prevent it from
slipping while the test is being conducted.
NOTE: An example where this holder may be useful
is for glass or ceramic tile, which may be difficult to
drill a center hole.
The E140-21 Threaded Ring Specimen Holder
incorporates a clamp plate and flanged clamp
ring to test slightly warped, rigid specimens.
The ring is threaded to the body of the holder,
which securely clamps the outer edges of
specimens up to 137 mm
(5.375 inch) diameter.
