Belt Abrasion Tester

The Belt Abrasion Tester is a laboratory testing instrument designed to evaluate the abrasive wear resistance of materials under controlled three-body abrasion conditions. You use a rotating pin pressed against a continuously moving abrasive belt under a constant dead-weight load, while both the pin rotation and belt speed are precisely controlled. An indexing linear slide ensures that the pin continuously contacts fresh abrasive material, providing repeatable and comparable wear results in accordance with ASTM G132.

Application

You can apply this tester in abrasive wear evaluation for the following materials and test scenarios:

(1) Abrasion resistance testing of metallic materials such as steels, non-ferrous alloys, powder metallurgy parts, and hard alloys.

(2) Wear performance evaluation of engineering ceramics and wear-resistant ceramic components.

(3) Abrasive wear testing of polymers, rubbers, engineering plastics, and composite materials.

(4) Performance comparison of surface-engineered materials including thermal spray coatings, PVD/CVD coatings, and protective wear coatings.

(5) Material screening and formulation comparison during product development.

(6) Quality control and consistency verification for industrial components.

(7) Research studies in tribology laboratories and academic institutions.

(8) Comparative testing between reference pins and test specimens under identical abrasive conditions.

Test Procedures

During testing, you press a rotating pin against a continuously moving abrasive belt under a constant dead-weight load. The belt is driven by a DC motor, while the pin rotates simultaneously to maintain uniform contact conditions.

A motorized indexing slide gradually moves the pin laterally across the belt width, ensuring that each wear pass occurs on unused abrasive material. This maintains consistent wear severity throughout the test and avoids track overlap.

After testing, you evaluate material wear by measuring mass loss, dimensional change, wear rate, and wear track profile.

Maintenance Information

(1) Inspect abrasive belt condition before each test and replace worn belts promptly.

(2) Clean pin holders and belt rollers regularly to prevent debris accumulation.

(3) Verify dead-weight loading components for free movement and correct alignment.

(4) Check indexing slide smoothness and recalibrate if lateral motion becomes uneven.

(5) Periodically inspect motors and electrical connections to ensure stable operation.
