Teammate pairs with most career home runs as TEAMMATES, not blindly adding up their team totals.

Pairs of teammates for seasons in which each played a comparable or significant amount as the other. So for the leading pair that would be 1954-1966, which does not include Eddie Mathews leading the National League in home runs in 1953 and does not include Hank Aaron after 1966 hitting 47,44,40,39, ... home runs.

Willie Mays had zero home runs for the Giants in 1972 in 49 At Bats before being traded to the Mets, so Mays and Willie McCovey for this post were teammates 1959-1971.

Lou Gehrig hit a total of one home run in 1923 and 1924 while Babe Ruth was leading the American League with 41 and 46, so those seasons are omitted. So their years are 1925-1934.

OK, you get the idea.

Of the three pairs with the most total home runs, Aaron/Mathews hit the most home runs but also had the most AB and the worst ratio AB/HR. Ruth/Gehrig had the fewest HR and AB but the best ratio.
