Abstract: A seal for sealing a shaft with respect to a housing can be inserted into a groove disposed circumferentially on a shaft bore. The seal is interrupted along its circumferential direction at a joint and two ring-end sections are formed. The seal has an outer surface facing radially outwards, an inner clamping surface facing radially inwards and opposing flank surfaces facing in the axial direction. At least one contact ramp is disposed on at least one ring-end section. At least one contact ramp is oriented obliquely with respect to the circumferential direction and obliquely with respect to the radial direction of the rectangular seal. The at least one contact ramp, starting from a non-stressed state of the rectangular seal, forms a first mechanical contact, pointing in the circumferential direction, between the opposing ring-end sections when the radius of the rectangular seal is reduced by prestressing the rectangular seal.

Abstract: The invention relates to an internally clamping rectangular seal (40) for sealing a shaft (20) with respect to a housing (10), wherein the rectangular seal can be inserted into a groove (13) disposed circumferentially on a shaft bore (12), wherein the rectangular seal is interrupted along its circumferential direction at a joint (42) and two ring-end sections (43, 44) are formed, and wherein the rectangular seal has an outer surface (40.4) facing radially outwards, an inner clamping surface (40.1) facing radially inwards and opposing flank surfaces (40.3) facing in the axial direction. Therefore, provision is made that at least one contact ramp (45.1, 45.2, 45.
