A skeleton oil seal consists of three parts: a sealing body, a reinforcing skeleton, and a self-tightening helical spring. The sealing body is further divided into the bottom, waist, cutting edge, and sealing lip, depending on the location. Typically, in its free state, the inner diameter of a skeleton oil seal is smaller than the shaft diameter, exhibiting a certain "interference fit."
Therefore, when the oil seal is inserted into the seal seat and shaft, the elasticity of the seal cutting edge and the contraction force of the self-tightening helical spring generate a radial clamping force on the shaft, resulting in optimal sealing performance.
