  • 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
  • DryLin E7 plastic linear plain bearings versus PTFE-line plain bearings
    . This whitepaper will compare how they outperform a competitive linear plain bearing technology, which uses a PTFE-based, bonded liner, in both wear and friction testing.
  • Why is PTFE Better Than Grease for Bushing Lubricants?
    A bushing's load and dynamic speed condition create heat through high surface interaction that generates friction. Heat, if not properly adjusted, will cause a bearing to fail. Lubrication is the key element in controlling bushing
  • What Does Self-Lubrication Mean?
    Q: "What Does Self-Lubrication Mean? A: For Polygon's PolyLube TM fiber-series self-lubricating bearing, a proprietary form of PTFE is used. In the form PTFE is used in the PolyLube TM fiber series bearings, lubrication occurs via the film transfer process. As the shaft rotates under normal cycling
  • How Do PolyLube Bearings Compare to Spring Style Steel Bearings?
    compared to a PolyLube bearing utilizing high-tenacity PTFE mono-filaments on the wear surface. The differences in frictional response between a spring steel bushing and the PolyLube bearing can be most easily conceptualized when thinking about the potential for intimate shaft contact: which bearing
  • Magnalube-G Case Study - Duke University
    of the Air Conditioning Refrigeration Department reported greatly reduced bearing trouble and, consequently, less equipment downtime in pumps and motors after he switched from conventional greases to PTFE reinforced grease.
  • Bearings that bear up
    Bearing selection looks at several key design metrics including anticipated loads, lifetime and reliability, ambient conditions, vibration, and cost. This information lets you choose between one of four basic bearing types: dry, semilubricated, fluid-film, or rolling-element bearings. Dry bearings
  • Direct-bond bearings challenge inserts
    , air cylinders, gas springs, solenoids, valve shuttles, small pumps, servomotors, and hydraulic and mechanical actuators. Bearings made of glass and bronze-filled PTFE or nylon go in machined bores and housings and are held in place by press fits, snap rings, staking, or pins. Most of the bearing
  • Lube-for-life journal bearings
    to embed allowing the film transfer (lubrication) process to continue unabated. The pin (mating surface) before and after PTFE film transfer begins. During break-in, PTFE fills valleys on the shaft. Once the process is completed, the coefficient of friction stabilizes and bearing wear practically
  • Nonlubed leadscrews
    PTFE-based coatings reduce leadscrew wear while practically eliminating maintenance. The stainless-steel leadscrews have threads coated with Danaher Motion's TriCoat PTFE-based solid-film lubricant. They perform well without oil or grease and with little to no maintenance even in environments
