Royal Caribbean does not strictly enforce a specific "per bag" weight limit in the same way that commercial airlines do, but they do provide general guidelines for guest comfort and safety. Technically, the cruise line suggests that each guest brings no more than two pieces of personal luggage, and each bag should ideally weigh less than 50 pounds (approximately 23 kilograms). This 50-pound suggestion is primarily to ensure that the shoreside porters and shipboard crew can safely lift and transport the bags from the pier to your stateroom without injury. Unlike airlines, you won't be charged an "overweight bag fee" if your suitcase is 55 pounds, but extremely heavy bags may be flagged or delayed. It is also worth noting that your biggest restriction isn't the ship's policy, but rather the airline you take to get to the port and the physical space available in your cabin. Most standard staterooms have limited floor space, so bringing massive, heavy trunks can make the room feel cramped once the luggage is delivered.
