A roll for continuous casting comprises a cylindrical roll rotatably mounted on a fixed axle and having a cooling chamber that surrounds the axle for receiving a flow of coolant. The axle is mounted on a roll support system. The roll support system comprises a first roll support connected to a coolant supply system and a second roll support connected to a coolant drain system. The axle comprises a first inlet connected to the first roll support, a first outlet connected to the coolant chamber, a second inlet connected to the coolant chamber, and a second outlet connected to the second roll support. A coolant flow circuit has a flow path from the coolant supply system to the coolant drain system through the first roll support, the first inlet, the first outlet, the coolant chamber, the second inlet, the second outlet, and the second roll support.
