POM Rod/Delrin Rod/Polyacetal Rod for Plastic Gears


POM is a kind of engineering plastic with good mechanical properties. POM together with UHMW PE, Nylon, PTFE are known as four most abrasion resistant plastics. It has almost the same rigidity as metal, so it's an ideal replacement material of copper, cast zinc, steel, aluminum and other metal materials. We are able to produce POM products without bubbles or cracks.

POM rod is an ideal replacement material of copper, cast zinc, steel, aluminum and other metal materials for its good mechanical properties and rigidity, and closeness to the metal material. It has properties like fatigue resistance and creep resistance. Good abrasion resistance, self-lubricated and friction, high thermal stability, good chemical stability and excellent electrical insulation. And it can be used in temperatures ranging from -50° C to +110° C.

Applocation

Bearings
POM bearings own excellent stability and good wear resistance in various kinds of moist environments.

Gears
POM has high stiffness and rigidity, good self-lubricating properties. So it has taken the place of metal gears in many applications. (Prior materials: Bronze, Stainless Steel)

Rollers
Guide rollers machined from POM rod operate smoothly and reliably in lift gate systems used to load cargo onto truck beds. (Prior materials: Cast Iron, Cast Aluminium)

Structural Keels
With excellent fatigue and impact resistance, POM is a suitable material of continuously loaded structural keel for prosthetic device. (Prior materials: Nylon, PU)

Slide Blocks
Low coefficient friction, wear resistant, self-lubricating, no need for lubricating oil.
