Application
Plastic resins for Gears & Mechanical Parts
Resins for gears, bearings, clips and sliding parts that need low friction, wear resistance and tight tolerances.
Typical parts
- Gears and cams
- Bearings and bushings
- Clips, buckles and fasteners
- Conveyor and chain parts
- Pump and valve parts
- Zippers and window hardware
What the material has to do
- 01Low friction and wear
Parts slide or mesh against each other or against metal.
- 02Fatigue resistance
Snap fits and gears are loaded millions of times.
- 03Dimensional stability
Gears and bearings need tight tolerances in humid conditions.
- 04Chemical resistance
Parts may see fuels, oils and cleaning agents.
Recommended resins
| Resin | Why it is used here | |
|---|---|---|
| POM Resin | Gears, bearings and clips; the standard for precision sliding parts. | See grades → |
| PA66 Resin | Gears and bearing cages that run hotter or need more toughness. | See grades → |
| PA6 Resin | Gears and wear parts, often glass-filled or lubricated. | See grades → |
| PBT Resin | Parts that need low moisture uptake and stable dimensions. | See grades → |
Grades used for gears & mechanical parts
Grades from our catalog that are commonly specified for this application. Open a grade for its data sheet, or send us your part requirements for a recommendation.
Processing notes
POM needs a warm mold (about 60–90 °C) for stable shrinkage and must not be overheated; nylons must be dried before molding and absorb moisture afterwards, which changes dimensions slightly.
General guidance only; follow the producer's TDS for each grade.
How we help
- Grade matchSend the grade you use now or your part requirements; we return options with data sheets.
- DocumentsTDS and the COA for the shipped lot; MSDS and compliance declarations where the producer issues them.
- Own compoundsPA6, PA66, PPA and MXD6 compounds from our Jiaxing and Shaoxing plants.
Gears & Mechanical Parts: common questions
POM or nylon for a gear?
POM for precision and low moisture uptake; nylon for higher temperature and toughness, especially glass-filled.
