Product Description

CCSi is pleased to introduce the Taber® Linear Abraser… the first wear and scratch tester specifically designed for measuring the abrasion resistance of finished products of virtually any size or shape!

The new Linear Abraser uses a floating head to follow the contours of the specimen, permitting the testing of finished products.

The limitations of specimen size and shape are virtually nonexistent, making the Linear Abraser ideal for testing molded plastic parts, automotive components, painted and coated parts, optical products… the possibilities are endless!

The Wearaser™ abrasive, similar in configuration to a standard pencil eraser, employs the same high quality materials found in other Taber® Abrasive Media, assuring consistent test results.

The Model 5750 features adjustable stroke length, speed, load, and a wide variety of Taber® Wearaser™ abrading media, allowing the customization of test parameters to suit virtually any requirement.

The optional sample tables provide additional flexibility for small or irregularly shaped specimens. Other optional attachments allow the conversion of the Linear Abraser to a scratch tester or a crock meter.

Please submit a Request for Quotation (RFQ) for the Taber Linear Abraser and any accessory or replacement items. Refer below to a description of the standard and optional components.

The included Adobe® Portable Document File (PDF) contains the Taber® Linear Abraser Model 5750 Set-Up chart. It is provided to assist in establishing specific test loads for the Model 5750:

  • Variable Stroke Lengths of 0.5, 1.0, 2.0, 3.0 & 4.0 inches;
    • Other stroke lengths are available.
  • CS—10 Calibrase® and H—18 Calibrade® Wearasers™ are included;
    • Customized Taber® abradants are also available.
  • Variable Stroke Speeds of 2, 15, 25, 40 & 60 cycles per minute;
  • Variable Load from 350—1100 g in 250 g increments;
    • Additional weight discs are available to increase the load to 1600 g.
  • Standard Attachment for Wearaser™ abrasive media;
  • 115 / 230 VAC Switchable Power Supply,
  • CE Marked.


The linear motion arm has an adjustable stroke length, variable to accommodate virtually any required contact surface area of a test specimen. The precision bearing on the splined shaft allows the abrading head to ‘float’, freely following the specimen surface whether contoured, irregular, or flat.

The test parameters are stroke length, speed, load, and number of test cycles; each of which can be altered to simulate actual use conditions, establish QC control limits, QA guidelines, or for empirical study

can be altered to simulate actual use conditions, establish QC control limits, QA guidelines, or for empirical study.

The test counter is programmable from 1—999,999 test cycles. It features an LCD back lit display for improved visibility.

There are two user selectable modes: RUN, for performing tests, and REFACE, which allows for the refacing of the abradant without having to reprogram the number of cycles.

Universal Kit [P/N 130572]
This attachment allows the simulation of actual use conditions. The performance of ‘real world’ testing is accomplished using your abradant material, or one of the many Taber® abradants. The Universal Kit is ideal for testing on flat surfaces.



Crock Meter Kit [P/N 130570]
The Crock Meter Kit is typically used to evaluate color fastness (transfer) on textiles, cellulose fiber derivatives, and other materials. The kit includes a 0.625 inch (15.875 mm) acrylic ‘finger’, clamp ring, and package of crocking cloths.

Also available are:

  • Replacement Acrylic Crock Finger [P/N 130818];
  • Replacement Crocking Cloths [P/N 130811].


Flat Specimen Table [P/N 130809]
A critical aspect in testing with the Taber® Linear Abraser is securing the specimen during the test. The flat table (shown on the left) is designed for rigid, flat specimens. They are mounted to the table using four adjustable mounting brackets. A leveling bubble and adjustable table supports are used to assure that the table surface is parallel to the work area.
Specimen Tables of many other configurations are available, or can be manufactured to suit a specific application.


Universal Specimen Table [P/N 131734]
The PanaVise® flexible mounting system enables the testing of all shapes and sizes of specimens. The PanaVise® is attached to the Linear Abraser to ensure a stable test platform. A low profile mount includes the patented ‘split ball’ design, allowing the vise head to be positioned on the x, y and z axis. The specimen can be tilted, turned or rotated to accommodate virtually any specimen configuration. Included are the base mount; low profile base; three interchangeable heads (vise head, flat table, wide jaw vise); and spacer.


  • Standard Grip Head for the Universal Specimen Table [P/N 131724]
    The nylon jaws of the Standard Head for the Universal Specimen Table open 2¼ inches (57.1 mm). The firm grip provides secure support. It is designed to avoid undue stress and strain on the specimen, providing reproducible and repeatable test determinations.
