Description
GenRotary is NextGen’s Rotary Abrasion Tester, widely used to evaluate wear resistance. It can conduct tests on materials such as cloth, paper, paint, plywood, leather, tile, glass and rubber. It tests the specimen by rotating it while in contact with the grinding wheel and applying the required pressure. The loss of weight reflects the change in weight of the specimen. The unit also comes standard with an intelligent power failure recovery function.
The test applies to material thicknesses between 6.35 mm and 40 mm. A flat square or round specimen of roughly 3.9″ (100 mm) is mounted on the system, which rotates at a fixed speed vertically. The wheels are lowered onto the material at a specific pressure. The X pattern of abrasion produced by the double rotary action allows for an accurate identification of the material’s wear and tear. The rotary abraser comes standard with a full range of auxiliary weights, specimen holders, abrasive wheels, a wheel refacer and a vacuum unit.

Dual Wheel Model
The dual wheel abrasion tester is suitable for testing a variety of materials such as fabrics, paper, coatings, plywood, leather, floor tiles, glass and natural plastics. The testing procedure involves positioning a rotating specimen between a pair of wearing wheels and applying a specified load. As the test material rotates, it impels the wearing wheels to cause abrasion on the test material. The weight loss resulting from the wear is determined by the difference in weight of the test material before and after the test.
The dual wheel rotary abrasion tester.
Three things separate the dual wheel machine from the single wheel one:
Wear process
The test material is placed on a turntable, where two grinding wheels exert a specific weight on the material to induce wear. As the material wears, the surface goes through all-around particle abrasion, forming a complete circular pattern. The grinding wheel spins along with the spinning sample plate, causing them to move against each other, which gradually wears away the material.
Test conditions
The machine can mimic real-world usage conditions or follow specific testing standards. It offers the flexibility to choose from different wear materials and accessories for various tests. It also allows you to select from two speeds, 60 and 72 revolutions per minute, and three different loads.
Vacuum cleaning
A vacuum pump’s suction arm is connected to an adjustable part at the back of the machine through a hinge. This allows you to adjust the height to match the thickness of different samples.
