Abstract
A rebuildable radial lip seal having a replaceable sealing element for sealing around a movable shaft and adapted for removable placement within a seal housing. The rebuildable radial seal comprises an annular sealing body which extends radially between an annular inner seal surface and an annular outer seal surface. The inner seal surface defines a first inner diameter and includes a circumferential rib which protrudes radially inward from the inner surface. An annular end flange is coaxially engageable with the seal body. The end flange includes a coaxially protruding annular rim which is engageable within the first inner diameter of the seal body to form a circumferential inner slot between the circumferential rib and the inner surface of the seal body and the annular rim on the end flange. An annular sealing element having an inner sealing lip is sealably captured within the inner circumferential slot formed between the seal body and the end flange. Fasteners coaxially secure he seal body and the end flange together and sealably compressed the axially aligned sealing element therebetween. A circumferential outer seal seals between the outer seal surface and a cylindrical bore within a seal housing.
