The invention provides a bearing ring quenching die. The bearing ring quenching die comprises a combined die 1 and a combined die 2, wherein the die bodies of the combined die 1 and the combined die 2are circular; circular upper pressing dies and circular lower pressing dies are respectively arranged on the two sides of the combined die 1 and the combined die 2; the upper pressing die of the combined die 1 has the same diameter as the upper pressing die of the combined die 2; the lower pressing die of the combined die 1 has the same diameter as the lower pressing die of the combined die 2; and through holes are formed in the centers of the combined die 1 and the combined die 2. The upper pressing die (or lower pressing die) of the combined die 1 and the upper pressing die (or lower pressing die) of the combined die 2 are in abutting joint inside a bearing inner ring (or a bearing outer ring). A suspension rod passes through the through holes and is fixed to a tray; and a wedge passesthrough the suspension rod
