Bearing assembly for supporting a printing cylinder or an anilox roll in a printing machine and printing machine

A bearing assembly for a printing machine, the bearing assembly comprising:

• at least one roller bearing provided to receive a shaft in an axis of rotation of the at least one roller bearing;
• a first support part provided radially outside of the at least one roller bearing and radially aligned with the at least one roller bearing to support the at least one roller bearing, wherein the first support part includes a radially outer surface having a dimension, relative to the axis of rotation, that varies to define a radially inner surface of a fluid chamber;
• and
• a second support part provided radially outside of the first support part and radially aligned with the first support part to support the first support part, wherein the second support part includes a radially inner surface to define a radially outer surface of the fluid chamber.

A bearing assembly for a printing machine, the bearing assembly comprising:

• at least one roller bearing provided to receive a shaft along an axis of rotation of the at least one roller bearing;
• a first support part provided radially outside the at least one roller bearing and radially aligned with the at least one roller bearing to support the at least one roller bearing, wherein the first support part includes a radially outer surface to define a radially inner surface of a fluid chamber;
• and
• a second support part provided radially outside the first support part, radially aligned with the first support part to support the first support part, and longitudinally fixed in position relative to the first support part, wherein the second support part includes a radially inner surface to define a radially outer surface of the fluid chamber.
