Adjustable settings enable the user to select the speed, stroke length and test load. The Linear Abraser includes six preset speed buttons, along with the ability to adjust the speed from 2 to 75 strokes per minute. Eleven stroke lengths are standard ranging from 0.2 inch to 4.0 inch.
The Wearaser® collet assembly is supplied with each Taber Linear Abraser, along with CS-10 and H-18 Wearaser abradants. The size and shape of a pencil eraser, the Wearaser is made using the same high quality Taber abrasive media found in our Genuine Taber abrading wheels. This permits the use of equivalent abrasive materials with the Linear Abraser as well as Taber’s Reciprocating Abraser and the Taber Rotary Platform Abraser.
The Multi-Head Attachment (sold separately), incorporates an additional spline shaft, permitting two tests to be performed simultaneously with the Linear Abraser.
With the diversity of products that can be tested with the Taber Linear Abraser, it is up to the end-user to determine a suitable clamp or fixturing device appropriate to their product. Click here for additional information on specimen mounting available from Taber Industries.

Due to the wide variety of test attachments that can be used with the TABER Linear Abraser (Abrader), there is no universal method to interpret results. The two most common methods include:
Cycles to a Specific End-Point – The number of cycles required to reach a predetermined end point, or the appearance or condition of the specimen after a fixed number of cycles. The evaluation criteria may include: loss in coating, change in gloss, color loss, or other changes in appearance. In these cases, the abraded sample is usually compared to a known standard of the material tested. When visually inspecting changes in specimen appearance, evaluations should be made using an agreed upon rating system such as a visual grading scale (e.g. five-step) or pass/fail criteria.
Weight (Mass) Loss – This technique measures how much material has been removed by abrasion, and is usually reported in milligrams.
L = A – B
where L = weight loss
A = weight (mass) of specimen before abrasion
B = weight (mass) of specimen after abrasion
Note: There is no standard formula to correlate test results between the Linear Abraser and Taber Rotary Abraser. Due to differences in how the wear paths are generated, testing parameters and the unique wear properties of each material prevents a universal formula from being devised. If you are attempting to correlate the results, Taber recommends correlating through experimentation to determine the appropriate settings.
