Abstract: A seal assembly (100) between an elastomeric seal component (110) and a surface (102) of a rotating component (104) which incorporates at least one micro-channel (106) having discrete branching elements (108, 108A) or micro-recesses (114). The micro-channels (106) are formed on either the surface of the rotating component (104) or the elastomeric seal component (110), and are configured to provide a uniform and unidirectional wear surface. The micro-channels (106) permit a controlled amount of lubricant to flow to the elastomeric seal region (R) area while creating a barrier to prevent lubricant axial migration beyond the elastomeric seal region (R). The controlled lubrication reduces seal wear, extends the seal life, and results in a reduced chance of leakage if the elastomeric seal component (110) is misaligned relative to the rotating component surface (102).

Abstract: A protective coating C is applied to an inner (2) or an outer (4) member of a rotary fluid bearing by sputtering to minimize scuffing, wear and premature failure of the members (2, 4) during starts and stops of the bearing. The coating C may include titanium, tungsten, chromium, amorphous carbon with or without metallic impurities, and hydrogenated amorphous carbon with or without metallic impurities. One of the members (2) is formed in two sections (10, 12) to accommodate assembly of the bearing and these sections abut at end faces (at 16). Features on each end face (at 16) are imparted to the other end face in a compression coining process to facilitate rapid and repeatable alignment of the two sections (10, 12) when separated and rejoined during subsequent manufacturing steps.

Abstract: A rotary air bearing (A) as shown in the Figure has a journal (2) provided with a pair of outwardly presented tapered surfaces located opposite the tapered surfaces on the journal, and a low friction liner (6) bonded to the tapered surfaces on the hub and having tapered surfaces which are separated from the tapered surfaces of the journal by small air gaps (g).
