The invention relates to a marine stern rolling wheel. The marine stern rolling wheel comprises a drum, a stern rolling wheel shaft assembly, a first bearing, a second bearing, a first bossing, a second bossing, a first bearing seat and a second bearing seat. According to the stern rolling wheel shaft assembly, a long shaft is replaced by two sections of short shafts, a large middle section of shaft is cancelled, and accordingly the equipment weight can be greatly reduced; the grease lubrication is adopted, a water lubrication system is cancelled, and accordingly only one-time grease needs to be added to ensure the long-time stable reliable work of the stern rolling wheel; a cellon sleeve is replaced by the copper bearings and accordingly the cost is reduced and the cost performance is improved. According to the marine stern rolling wheel, the cost performance is high, the equipment weight is light, and the operation is safe and reliable.
