Shear bearing

A shear test conducted on a four ball friction testing machine for bearings, especially tapered roller bearings. The four ball friction tester is a specialized instrument used to test the extreme pressure performance (PB, PD, ZMZ) and anti-wear performance of lubricants. It evaluates the frictional properties of materials by simulating sliding friction.

When conducting shear bearing tests on a four ball machine, tapered roller bearings are usually used as samples. This experiment aims to evaluate the performance of bearing materials under shear force, including their load-bearing capacity, wear resistance, and shear stability. By simulating actual working conditions, the performance of bearings under specific lubricants can be understood, providing important basis for the selection and use of bearings.
