摘要

A self-lubricating assembly (40) includes an oil supplying sub-assembly (41) having protrusions formed on an oil applying piece (412) located in a fixing seat (411) for contacting elongated guiding grooves (11) of a guide-way (10). An oil transmitting sub-assembly (42) has a connector with an end inserted through oil supplying assembly and an oil containing substance contacting the oil applying piece. An oil container (43) storing lubricating oil and detachably fixed at the connector has an oil transmitting element that contacts the oil-containing substance.
