Abstract
A universal joint includes a bush, a bearing journal supported in the bush by a bearing and a seal assembly configured to form a seal between the bearing journal and the bush. The seal assembly includes an outer body formed from a first material having a first hardness, and a reinforcing body at least partially embedded in the outer body is formed from a second material having a hardness greater than the hardness of the first material. The reinforcing body contacts and forms a slip surface for a rolling element of the bearing. The reinforcing body and the outer body are configured such that the reinforcing body compresses a portion of the outer body against the journal when the seal assembly is mounted on the bearing journal.
