The invention discloses an abrasion tester of a pot type rubber bearing abrasion plate. A three-dimensional hollow bearing frame is vertically arranged on a horizontal bearing base through vertical columns arranged at the bottom of the three-dimensional hollow bearing frame; a sample clamp above is fixed at the top of the bearing frame; a sample clamp below is fixed at the top of a plunger of a vertical loading plunger cylinder; a movable rectangular abrasion plate is horizontally arranged between the two sample clamps; a push rod is arranged on one side of the abrasion plate; a spoke type sensor, an anti-turning support plate, an inclined pad and a horizontal actuator are sequentially fixed at the input end of the push rod; a sealing simulation environment box with a door cover is arranged inside the bearing frame; the lower part of the sample clamp above, the upper part of the sample clamp below and the abrasion plate are positioned inside the box body. The abrasion tester can be directly applied to experiment under room temperature condition or experiment under complex simulated working condition, and the abrasion tester is relatively simple and compact in structure and relatively low in production and purchase cost.
