ELASTOMERIC COMBINED SEAL AND SPRING ABSTRACT An elastomeric combined seal and spring formed of uniformly resilient flowable rubber-like material and comprised of a one-piece annular body of uniform cross- sectional configuration throughout, which is of generally right angled polygonal shape and having a pair of opposed concave working surfaces spaced a distance only 60%-75% of its maximum radial dimension, measured at its corners, and its convex corners having a convexity of only 14%-16% of said maximum radial dimensions, the concavity of said sur- faces being 17%-33% of said dimensions, thereby providing an elastic seal which will function as a forgiving spring in support of a self-adjusting, self lubricating split ring annular bearing and thereby perfect a lasting seal against an annular surface while the latter is moving relative thereto at high speeds for prolonged periods.
