ABSTRACT:
A roller closing device is provided with an inner element and with an outer element. These two elements are arranged at least partially in a coaxial manner. The inner element can be deflected radially with respect to the outer element by the use of at least one elastic body which is arranged between the two elements. This elastic body is configured as a rolling diaphragm. A seal is configured between the inner element and the outer element. The seal closes off a gap between the two elements to prevent impurities from entering the roller closing device when any radial deflection of the inner element takes place.
