General Info

ZL® 250 MO is a Type 6/6 nylon with molybdenum disulphide (MoS2) added to increase crystallinity, and therefore improve the bearing and wear characteristics of the base resin. With a lower coefficient of linear thermal expansion than unmodified 6/6, bearings made from ZL® 250 MO are less likely to seize in service. Color is black.

Key Properties

  • Enhanced Bearing & Wear Properties vs. Unfilled ZL 250
  • Enhanced Dimensional Stability vs. Unfilled ZL 250
  • Increased Crystallinity

Limitations

  • High Moisture Absorption
  • Limited Resistance to Strong Acids & Alkalies

Applications

  • Bushings & Bearings
  • Conveyor Wear Components
  • Gears
  • Metal Replacement Applications
  • Pulleys
  • Roller Wheels
  • Sheaves
  • Wear Pads
  • Bearing & Wear Parts for a Wide Range Automated Equipment
  • Valve Seats & Seals

Manufacturer Trade Names

  • ZL® 250 MO

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.
