Possible uses:

1. Bearing blocks (for wheels, scoops, arms, pulleys...)
2. Sliders
3. Skids for bottom of machine

Tips:

HDPE and Delrin have high strength and stiffness, good temperature and abrasion resistance and a low coefficient of thermal expansion. Some applications include: bearings, gears, and water pump parts.

HDPE or Delrin and steel are an excellent combination for bearings. Simply drill a hole in the Delrin and a steel shaft will rotate or slide inside it easily.

To use as a press fit on a 1/4" shaft, drill to size D and use arbor press to force it on. Be careful not to use thin pieces as they might crack when forcing the press fit on.

Tools:

To modify you can use the following tools: Mill, Bandsaw, Drill, Taps

You should be careful when using: Sander (go slowly, Delrin will burn if it gets too hot)

You should not use: Lathe, Grinder, Shear, Notcher, Brake, Wire bender
