PURPOSE: An anti-wearing character tester of the sliding bearing for the construction machinery is provided to develop more of the materials of the abrasion resistance used as the pin and bush, to design to minimize the abrasion, and to increase the reliability of the sliding bearing product by improving the performance like the durability of the pin and bush and abrasion resistance. CONSTITUTION: The anti-wearing character tester of the sliding bearing for the construction machinery includes: a pendulum swing unit; torque cell(170); a pin-push assembly(200); and a boosting unit. The pendulum swing unit converts the rotational motion of the rotary actuator(120) through the eccentricity combination of the eccentric weight(130) and link into the pendular and oscillation. The pendulum swing unit establishes in the perpendicular frame(110) one side in order to rotate the rotary shaft(160). The torque cell is installed in part of the rotary shaft located at the upper part of the mainframe(100) and measures the torque of the rotary shaft. The pin-push assembly is fixed and combined between both bearing housing(180). The boosting unit is installed in the lower part of the pin-push assembly. The pendulum swing unit includes: a rotary actuator; an eccentric weight; a driving link(140); and a follow link(150). The rotary actuator is installed at the lower part of the perpendicular frame. The eccentric weight rotates by axis-connecting to the rotary actuator. The driving link is combined in the part of the eccentric weight to rotate and does the constant section pendular rotation by being axis-combined to the rotary shaft.
