A mechanical assembly includes: a shaft having a central axis; an outer member having a bore disposed about a shaft, either of the shaft or the outer member having a gland defined by a circumferential surface and at least one radial surface, the other of the shaft and the outer member being angularly displaceable about a central axis. The seal has an annular body disposed within the gland and formed of a flexible material, preferably plastic or elastomeric material, the annular body having a body portion with an inner radial end and an outer radial end. An inner seal lip extends radially inward from an inner end of the body portion and is configured to engage a shaft. An outer seal lip extends radially outward from an outer radial end of the body portion and is configured to engage an outer member. 一种机械组件，包括：轴，具有中心轴线；外构件，具有绕着轴布置的孔，轴或外构件中的任一者具有由周向表面和至少一个径向表面限定的压盖，轴和外构件中的另一者能够绕着中心轴线在角度上移位。密封件具有布置在压盖内并且由柔性材料形成的环形本体，柔性材料优选为塑料或弹性体材料，环形本体具有主体部分，主体部分具有内径向端部和外径向端部。内密封唇从主体部分的内端部在径向上向内延伸并且被构造为与轴接合。外密封唇从主体部分的外径向端部在径向上向外
