Linear abrasion tester
Model 5750 Taber Industries

The TABER® Linear Abraser (Abrader) – Model 5750 has been engineered to test either contoured or flat surfaces, making it ideal to evaluate finished products of all sizes. To expand the versatility of this instrument, the Linear Abraser can be configured with optional test attachments to evaluate the relative resistance or susceptibility of a material surface to scratch, mar, gouge, and scrape (or different types of abrasion tests).

The Taber Linear Abraser incorporates a horizontal arm that reciprocates in a linear motion. Attached to the end of the arm is a precision bearing spline shaft that creates a ‘free-floating’ test system and permits vertical movement. Scratch or mar tools are affixed to the bottom of the spline shaft and a weight support is mounted to the top. As the horizontal arm strokes back and forth, the test system raises or lowers vertically as the test attachment follows the contours of the specimen.
