PURPOSE: A coupling device for equipment implements is provided to prevent the lubricity of bearing sections from being damaged at each spot when the equipment is in service, to prevent seizure during the rotation of a bearing, not to need frequent feeding of grease to the bearing sections from outside, and to improve noise absorbability. CONSTITUTION: A coupling device for equipment implements is composed of a metal based sliding material(7) for storing a lubricating oil and/or lubricant interposed between clearance formed by an implement bush(1) made from steel and an implement pin(4) of an implement for a construction equipment. A hole is drilled through the metal based sliding material and lubricating oil and/or lubricant is stored in the hole. The sliding material is a metal based porous sintering sliding material having a vent of 5¯30 volume percent. |
