Lubricant and PTFE Filled Plastics for Sliding and Bearing Parts

Lubricated compounds for sliding

PTFE powder and oil-filled grades reduce friction against metal or polymer mates.

Gears, bushings, and slides sometimes specify PTFE-filled POM or PA instead of plain acetal when friction or noise is critical.

Fillers can lower strength and change shrink; they are not free drop-ins for unfilled POM.

Pair lubricated resin with mate material on the same RFQ so wear testing matches the assembly.

When to specify it

Lubricated fill checklist

Use this on RFQs and BOMs before you lock a filled grade.

  • State PTFE or oil-filled suffix.

  • Name mate material (steel, PA, POM).

  • Note load speed qualitatively.

  • Compare noise requirement on T1.

Trade-offs

Routing

POM vs nylon slide

Moisture and wear tradeoffs.

Acetal POM

  • Low moisture
  • Good precision gears
  • Standard lubricated grades exist

Glass filled PA

  • Higher load
  • Moisture sensitive
  • Noisy if dry

FAQ

FAQ

PTFE fill same as PTFE parts?

Filled compound differs from pure PTFE billet routes.

Food contact lubricated POM?

Supplier-documented grades only.

Over-lubricate by adding grease?

Secondary grease is a different process step.
