LNP™ COMPOUNDS - WEAR AND FRICTION SOLUTIONS - BEARINGS, BUSHINGS, CAMS AND SLIDERS

At the push of a button, windows move, doors lock, copies get made, and HVAC comes to life. These electromotive actions require gears, bearings, bushings, and other wear surfaces to provide smooth, reliable, actuation forces. LUBRICOMP™ and LUBRILOY™ compounds can help deliver the high-quality performance required.

THERMOPLASTIC BEARINGS

While resistance to wear is important for thermoplastic bushings/bearings, low friction can be more important. Heat generated from friction is often the limiting factor in plastic bearing applications. The operating load (P) and speed (V) of the application can be compared to the allowable, or “Limiting PV” of a candidate material. The data shown below was generated using a cylindrical half bearing test configuration, but modern thrust washer testers can be used to develop PV maps as well.


INTERNALLY LUBRICATED COMPOUNDS

The addition of an internal lubricant to a thermoplastic material can improve the wear resistance and reduce the coefficient of friction in plastic parts. Traditional lubricants like MoS2, PTFE and PTFE/Si blends are common, with reinforcements like glass and carbon fibre adding strength and modulus. High temperature resins are sometimes required to resist deformation from friction generated heat.

WEAR AND FRICTION SOLUTIONS - EARINGS, BUSHINGS, CAMS AND SLIDERS


In addition to the journal bearing test described earlier, material performance data can be generated by doing thrust washer wear testing at multiple loads (P) and speeds (V). Plotting the results for wear rate, COF and temperate can give insight into the performance window of a particular grade. Data shown at left is multipoint wear rate data for LUBRICOMP UFL36S.
