  • Effects of Graphite Type, Purity and Concentration on Grease Performance (.pdf)
    from ASTM D2266 were augmented with graphs of coefficient of friction plotted as a function of time and optical micrographs of four-ball wear scars for each sample tested. Four-Ball Wear testing (D2266) shows that grease performance is a function of graphite type. There is very limited evidence
  • About Cobra Solid Lubricant (CSL)
    CSL (Cobra Solid Lubricants) is graphite based solid lubricant specifically designed for ball and roller bearings. It is a mixture of graphite and binders that is prepared in such a way as to allow the mixture to be injected into the clean bearing and then thermally cured to harden the mixture
  • Bearings take the heat
    and oil lubricants aren't an option. Graphite-metal alloy bearings, in contrast, can operate dry for over 50 hr in some cases until fluid is reintroduced. Agrease-filled ball bearing on an oven-door latch seizes and keeps the door from latching. It turns out the +550 F oven temperatures over time
  • Talk About Speed and Life
    the maximum speed capability will be decreased , although it may still be acceptable for your application. The reason is that the CSL forms a barrier layer of graphite to prevent metal to metal contact between the ball and races of the bearing. In addition to preventing metal to metal contact, the CSL
  • Talk About Shaft and Housing Fits and Roundness
    When ball bearings have been processed with CSL, the CSL fills the entire space between the inner and outer race for the width of the bearing. It will mold around the cage and form to the geometry of that space. Since the graphite is a non-flexible solid, its roundness is determined
  • Medical Device Link .
    rotary tables. Speeds up to 250 rpm are possible on the rotation axis and up to 150 rpm on the swivel axis, with a swivel range of +-110 . A concrete polymer base provides rigidity, vibration dampening, and high thermal stability. Spindle motors are liquid cooled with hybrid ceramic ball bearings
  • Out of the Lab and Onto the Links
    New high-tech clubs and balls are designed to hit golfers' sweet spots Tight Lies ST drivers and fairway woods from Adams Golf feature shafts made of steel and graphite. Spalding's multilayer Strata Tour Ultimate consists of a concentrated tungsten core, high-acid ionomer mantle, and Zythane II
  • Advanced Manufacturing: Rapid Roughing of Tough Materials
    into a proprietary technology called BlueArc, (generically known as ECDM). in Independence, Ky., to build two machines for ECDMing blisks out of solid Inconel billets. Recall that EDM removes metal by placing a wire, or an electrode -- a shaped graphite tool (anode) -- near, but not touching, the workpiece
