Abstract
The invention relates to a saw chain for a motor-driven chain saw equipped with a guide bar and a drive motor for imparting a force to the saw chain for moving the latter around the guide bar in a predetermined running direction. The chain saw is further equipped with a device for supplying lubricating oil to the saw chain during the movement thereof. The saw chain includes a plurality of cutting links, a plurality of driving links and a plurality of side links all pivotally interconnected by rivets. Abrasive small particles become entrained in the lubricating oil which can lead to premature wear at the pivot locations. The saw chain of the invention includes a hold-back element in front of a rivet to hold back such particles and yet not affect the flow of lubricating oil to the pivot connection.
