Four Ball Friction Tester - China

The microcomputer-controlled four-ball friction testing machine can also be used for testing the anti-wear performance of lubricants.

With special accessories, it can also perform end-face wear tests and measure the friction coefficient of friction pairs.

This machine is mainly suitable for industries such as petrochemicals, iron and steel metallurgy, transportation, and higher education institutions.

Standards

When conducting tests, the microcomputer – controlled four – ball friction testing machine needs to comply with the following relevant national or international standards: (1)GB/T 12583 – 98: Method for Determination of the Extreme – Pressure Properties of Lubricants (Four – ball Machine Method).

(2)GB 3142 – 82: Method for Determination of the Load – Carrying Capacity of Lubricants (Four – ball Method).

(3)SH/T 0189 – 92: Method for Determination of the Anti – wear Properties of Lubricating Oils (Four – ball Machine Method).

(4)SH/T 0202 – 92: Method for Determination of the Extreme – Pressure Properties of Greases (Four – ball Machine Method).

(5)SH/T 0204 – 92: Method for Determination of the Anti – wear Properties of Greases (Four – ball Machine Method).

These standards specify the requirements for the test methods, test conditions, data processing, etc.

of the four – ball friction testing machine to ensure the accuracy and comparability of test results.
