Abstract
In order to ensure that the working life of the sealing device is at least comparable to that of the remaining parts of the crawler track, the resilient annular element comprises a first annular portion and a second annular portion. The first annular portion has a cross-section in the form of a bulge, while the second annular portion has a cross-section in the form of a boss. The first annular portion is delimited by an annular contact surface which, when the annular seal is assembled, but not mounted in its seat, forms together with the incident joining plane of the rigid annular sealing element, an angle “&agr;” of between 0° and 30°.
