Abstract: ABSTRACT A MULTI-PARAMETER PERFORMANCE TESTING APPARATUS The present disclosure relates to a multi-parameter performance testing apparatus (100) for evaluating at least one test bearing (226) under controlled electro-mechanical conditions. The apparatus (100) comprises a platform (202), a drive motor (204) operatively coupled with a shaft (210), support bearing assemblies (212), a mechanical loading unit including an actuator (214), an actuator drive (216) and a load cell (218), and a test-bearing housing (221). The housing (221) accommodates a shielding member (224), a test bearing (226) and a load bearing (222). An electrical loading unit applies electrical excitation across the bearing assembly and measures one or more electrical parameters including impedance, capacitance and current flow. An accelerometer (228) coupled with the housing (221) measures vibration response. The apparatus (100) enables comparative evaluation of electrical insulation and vibration-damping characteristics of different shielding members (224) during controlled rotation and radial loading.
