Abstract
A seal for sealing around a shaft includes a radially outer clamp-in element to be clamped into a housing, an intermediate membrane part extending radially inwardly (toward the shaft) at an angle from the clamp-in element, and an angled base part at a radially inner end of the intermediate membrane part. A spring is received in a receiving groove that forms a spring pocket in the base part, and the spring exerts a contact pressure of a seal lip of the base part against the shaft. In a pressureless state without a pressure differential across the seal, the spring pocket has a width larger than the sectional diameter of the spring and thus forms a free play space for the spring in the pocket.
