Abstract
Ultraviolet-transparent seals, flange, and sleeve assemblies are used in actuator pivot cartridges for hard disk drives to cure adhesive located inside the pivot housing. The assemblies are formed from silica glass, polymers, or other suitable materials, and focus UV light into hard to reach, high aspect ratio areas between the pivot bearings, sleeve, and shaft. Some of the assemblies use transparent components with convex or fresnel lenses formed into their geometry. With these designs, UV light can enter the pivots axially and/or radially to reach and cure the adhesive regardless of its location.
