PURPOSE: An actuator with an anti-wear part is provided to prevent abrasion and damage by securing the smooth rotation of a shaft bearing embedded in the anti-wear part. CONSTITUTION: An injection nipple(21) is exposed on the outer side of a body(11). An oiling hole(20) is connected to the injection nipple and to the outside of a shaft bearing(13) mounted inside the body. An injection hole is connected to the oiling hole and formed on the upper side of the body. An anti-wear part(30) is settled on the top of the body and a main shaft(12) passes through the anti-wear part. The anti-wear part supplies lubricating oil, supplied through the oiling hole, to the inside through the injection hole, thereby preventing the abrasion of the main shaft. |
