Excimers Smooth the Path to Well-Lubricated Bearings
Applications in the defense and aerospace industries have increased demands for spherical plain bearings that require less maintenance and that yield higher performance and longer life. These demands, in turn, have initiated the development of laser micromachining systems to improve bearing process technologies.In most cases, bearing performance and lifetime directly relate to the manner in which lubricants recirculate within the bearing assembly. Laser-machined blind-depth lubricating grooves...
