  • The Bonded-On Bearing
    , this just hasn 't been practical. PTFE and moly-filled coatings might work on light loads that move slowly with PV (pressure X velocity) levels of 5,000 to 10,000 lb/in.-sec. But this PV just isn 't high enough to replace traditional bearings. Abrasion is another problem and erosion can literally wash
  • Bearings that bear up
    are probably the simplest and least expensive of all. They blend polymers, such as PTFE and nylon, with molybdenum disulfide, graphite, and other inorganic powders to lower friction and add strength. Dry bearings closely conform to the shape of their mating shaft or thrust surface and are mostly
  • Lube-for-life journal bearings
    Composite journal bearings can operate without external lubrication, even in harsh environments that challenge most conventional types. Lube-free composite journal bearings from Polygon, Co., Walkerton, Ind., use interwoven PTFE super filaments. The material provides small pockets for contaminants
  • 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
  • Bearings take the heat
    to 1,000 F (or higher in nonoxidizing environments), beyond the range of liquid and solid lubricants such as PTFE and molydisulfide, and above the melt point of polymer bearings. They also work at cryogenic temperatures down to 450 F. Graphite alone lacks the durability for bearings so it is often
  • 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
  • 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
  • Sealing Options for Self-Lubricating Bearings
    this problem. In the case of PolyLube TM Fiber and MRP bearings, the liner architecture is designed with macroscopic pockets that allow debris to be ingested without compromising the transfer of PTFE from the bearing ID to the shaft surface. No matter how good the design of any bearing, there is still
  • Why are Rod End and Spherical Bearings Teflon-lined?
    A PTFE (Du Pont trademarked product) liner in a spherical bearing or rod end is a component that allows the unit to be "self-lubricating". Metal on metal bearings need to be lubricated. In certain applications this can be difficult to accomplish. Grease lubrication attracts dirt and may prematurely
  • Plastics that don't wear out their welcome
    urethane bearings led to the selection of a nylon 6/6 compound with aramid fiber and PTFE. The bearings separate the spinning metal cutting blades, which instantly cut through lines, nets, and weeds before they become entangled or damage the running gear. The bearings are water lubricated
