Similar to Taber's Linear Abraser, a test attachment is secured to the bottom of a vertical spline shaft and accessory weights may be placed on a weight holder affixed to the top. A precision bearing on the spline shaft creates a "free-floating" test system. As the test arm moves in a linear motion, the "free-floating" system will raise or lower as the test attachment follows the contours of the specimen being tested - curved or flat.
The base load of 500 grams consists of the test attachment, spline shaft and weight holder. Accessory weights of 1000, 2000 and 4050 grams are included and can be added to the weight holder to increase the test load. With a high torque motor, the Heavy Duty Linear Abraser can accommodate a maximum testing load of 20 lbs. (weight sold separately).
