General Info

Torlon ® 4435 PAI is specifically designed to provide exceptionally low wear performance in non-lubricated applications even at high pressure and velocity (PV) conditions. With a proprietary blend of carbon fiber, graphite, mica and PTFE fillers, 4435 offers the best possible advantages of lower friction and increased wear resistance as compared with other more common Torlon Bearing Grades. Not only is Torlon 4435 particularly suited to applications where lubrication is impossible or undesirable, it provides an additional margin of safety for lubricated systems in the event that lubrication is lost. NOTE: This less-common bearing grade is NOT AVAILABLE FROM STOCK, but rather can be offered ONLY BY SPECIAL ORDER ... long leadtimes and large minimum order quantities may apply when ordering these grades in sheet or rod forms.

Key Properties

Limitations

  • Torlon® PAI has a relatively high moisture absorption rate, parts used in high temperatureservice or made to tight tolerances should be kept dry prior to installation. Thermal shock resulting indeformation can occur if moisture laden parts are rapidly exposed to temperatures above 400°F (205° C).

Applications

  • Bobbins
  • Bushings
  • Clutch Rollers
  • Pistons
  • Seal Rings
  • Sliding Vanes
  • Thrust Washers

Manufacturer Trade Names

Boedeker Plastics, Inc. stocks & supplies plastic sheet, rod, tube, film and custom profiles and machine parts from these shapes that are produced from plastic resin. In many cases the manufacturer of the shape has their own product trade name. If your specification calls for a specific resin grade or manufacturer trade name, we can supply a shape made from that resin to meet your specification or suggest an equal. If you require a specific resin or brand it must be specified at the time of order.
