A saw chain for a motor-driven chain saw (1), including for a harvester for the lumber industry, is formed from center drive links (10) and lateral connecting links (11). The drive links (10) and the connecting links (11) are pivotally connected to each other via rivets (9). The connecting links (11) are configured, in part, as cutting links (14). These cutting links include a cutting tooth (15) and a forward running surface (16) and a rearward running surface (17). The forward running surface (16) is approximately at the elevation of the leading rivet opening (12) and the rearward running surface (17) is approximately at the elevation of the trailing rivet opening (13). The rearward running surface (17) is configured extended in a direction opposite to the running direction (8) of the saw chain (5). A first radius (18) is the maximum distance of the axis (22) of the leading rivet opening (12) to the region (19) facing toward the forward running surface and lying in the running direction. A second radius (20) defines the maximum distance from the axis (23) of the trailing rivet opening (13) of the connecting link (11), which is next adjacent in the running direction (8), to the region (21) of the connecting link (11). The region (21) lies facing toward the rearward running surface (17) opposite to the running direction (8). In order to obtain a long service life and good saw chain movability, it is provided that the second radius (20) is greater than the first radius (18) and the sum of first radius (18) and second radius (20) corresponds approximately to the distance (b) of the axes (26, 27) of the rivet openings (24, 25) of a drive link (10) arranged between the connecting links (11).
