Taber Rotary abraser 5135 / 5155
Taber abrading wheels produce characteristic rub wear action.
Mounted to a rotating turntable, specimens are subjected to the
rub-wear action of two abrasive wheels. Driven by the test sample,
the wheels produce abrasion marks that form a pattern of crossed
arcs over a circular ring approximately 30 square centimeters. This
reveals abrasion resistance at all angles relative to the weave or
grain of the material.
Taber Abrasers Model 5135 or 5155 offer the following standard features:
-
Specimen turntable speed control options of both 60 rpm and 72 rpm.
-
Easy-to-use operator interface that includes tactile feel buttons and a four line digital display. Simple on-screen instructions allow the operator to change the test parameters via the MENU button. An internal memory stores the settings.
-
A vacuum system is included and is critical for the proper operation of the instrument. The vacuum nozzle(s) is hinged to an adjustable mounting at the rear of the housing. A precision vacuum nozzle adjustment control allows the height to be modified for accommodating varying specimen thickness.
-
Precision stainless steel weights of 250 grams and 750 grams are furnished to provide standard wheel loads of 500 and 1000 grams. Weights are marked to show total load on each wheel. This marking includes the weight of the abrading arm (250 grams).
-
A Quick Release Mounting Hub permits quick wheel mounting without the need of a locking nut, increased clearance for the vacuum pick-up nozzle and a larger viewing area for the test specimen. A beveled retaining nut provides a positive locking force on the wheel hub retaining lip making certain that the wheels remain securely fastened until disengaged.
-
Assembled in a sturdy, sealed aluminum housing.
