Abstract
A method of manufacturing a hub seal is provided. In the method, a lip reaction force F/hub diameter D and a lip surface roughness R are selected from within a designed region, which is a region of the lip reaction force F/hub diameter D and the lip surface roughness R, set in advance on the basis of a value (lip reaction force F/hub diameter D) given by dividing a reaction force F, which is a value of a reaction force of the side lip in an in-use state, by a hub diameter D, which is a value of a diameter of a hub, and the lip surface roughness R, which is a value of a surface roughness of a seal surface of the side lip. The hub seal is designed such that the lip reaction force F/hub diameter D and the lip surface roughness R become the selected lip reaction force F/hub diameter D and lip surface roughness R. The hub seal is manufactured based on the designed hub seal.
