Cutting assembly of a chainsaw and saw chain

A cutting assembly for a handheld motor-driven chainsaw, said cutting assembly comprising:

• a saw chain having a plurality of pivotally interconnected chain links wherein a portion of said chain links are drive links having respective drive bases;
• a guide bar having a peripheral edge defining a guide groove having side walls;
• said guide bar being configured to guide said saw chain along said peripheral edge;
• each one of said drive bases having side surfaces and being configured to be slidingly guided between said side walls of said guide groove under the formation of a friction pairing;
• a plurality of lubricant pockets formed in at least one of said side surfaces and being open toward the side wall of said guide groove corresponding to said one side surface and said lubricant pockets being otherwise closed;
• said one side surface having a flat sliding surface outside of said lubricant pockets which is configured to slide along the side wall of said guide groove corresponding thereto;
• said lubricant pockets having a mean diameter (d) lying in a range of 0.6 mm up to and including 1.0 mm and a maximum depth (t) of said lubricant pocket lying in a range of 0.04 mm up to and including 0.12 mm;
• and,
• said mean diameter (d) having a ratio to said maximum depth (t) of 5.0 up to and including 25.0.
