  • 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
  • Plane Bearings That Grease Themselves
    to their simplicity and low up-front cost, plane bearings can be made of resin with added lubricants. During operation, the lubricants transfer onto the metal mating surfaces. Polytetrafluoroethylene (PTFE), graphite, molybdenum disulfide (moly), and silicone are commonly added to the resin for lubrication
  • The Bonded-On Bearing
    They are good enough for NASCAR engines. Bonded bearing surfaces are coatings made from high-performance polymers reinforced with hard nanosized particles. Edited by Jean M. Hoffman Most engineers would jump at the chance to replace bearing inserts with dry lubricants. In many cases, of course
  • Ceramic Bearings Save Energy, Extend Life
    and valleys on both surfaces. Lubricants fill in these valleys with incompressible fluids like oil and grease. This prevents metal-to-metal contact between ball and race. But if the peaks do touch, the contact area is so small that even a small force on the ball or race results in pressures exceeding
  • Good grease, good landing
    aerospace components keep rolling under extreme loads and corrosive environments. Printer-friendly version. Jason Wincuinas. Nye Lubricants Inc. Fairhaven, Mass. The C-5 galaxy military transport when fully loaded weighs up to 380 tons. E-2C wheel assembly bearings after the wash test. The bearing
  • Bearings That Lube for Less
    heat up to about 120 F without any performance loss. However, synthetic oils can boost performance if the bearing must operate in harsher settings where the ambient temperature is below 30 F or above 200 F. Adding substances like graphite to the lubricants can further extend performance. Oil content
  • Spherical-roller bearings graduate to a new class
    commonly used in fatigue-life considerations and is valid for lubricants without EP additives. When lubricants contain such additives, consult the manufacturer or reference information at www.skf.com. Equivalent dynamic bearing load for spherical-roller bearings is calculated from. P = Fr + Y1Fa when
  • Bearing Swap: If You Can't Take the Chill, Get Out of the Cooler
    are not affected by periodic wash downs which can wash away secondary lubricants. All the rollers on three of the plant’s four coolers have been equipped with the new bearings, 1,150 bearings in all. The Duralon bearings have lasted over 18 months to date, with the original test bearings working
