Cast nylon (PA6) and glass-filled nylon wheels carry high loads with almost no rolling resistance, resist water, alkalis and most solvents, and keep working where rubber or PU would swell.
Nylon is the economical wheel for dry indoor logistics: trolleys, shelving carts, flow racks and FIFO systems.
Material Grades & Properties
Cast Nylon (PA6) Grades We Machine
| Grade | Standard | Characteristics |
|---|---|---|
| PA6 cast | monomer cast | high load |
| Glass-filled PA6 | injected | higher loads and temps |
Key Properties of Machined Cast Nylon (PA6)
- ✓Very high load per wheel size
- ✓Almost no rolling resistance
- ✓Resists water, alkalis, most solvents
- ✓Hard tread: can mark painted floors
Typical tolerances:Hardness and dimensional check per batch
Applications for Cast Nylon (PA6) Parts
- dry indoor logistics
- trolleys
- flow racks
- washdown areas

Finishes
Zinc-plated brackets
| Bracket finish | What it does | Specify it when |
|---|---|---|
| Zinc plating (blue/white) | Baseline corrosion protection | Standard dry indoor use |
| Chrome plating | Hard, decorative, easy to clean | Visible / cleanroom-adjacent equipment |
| Powder coating | Custom color, good corrosion resistance | Brand colors, outdoor-adjacent use |
| Stainless steel 304 | No plating to fail | Washdown, food, medical |
| Stainless steel 316 | Resists chlorides | Salt, brine, marine air, harsh cleaning chemicals |
Testing
Wheel hardness and dimensional check per batch
| Selection factor | Rule of thumb | Effect on performance |
|---|---|---|
| Load sizing | Total load ÷ 3 (not ÷ 4) | On uneven floors only three wheels carry the cart |
| Wheel diameter | Bigger rolls easier | Larger wheels cut push force and bridge gaps |
| Tread hardness | Softer = quieter, harder = easier rolling | Pick the softest tread that carries the load |
| Bearing choice | Precision ball for manual pushing, roller for heavy loads | Bearings dominate rolling resistance at high load |
| Swivel vs rigid | 2 swivel + 2 rigid is the standard cart setup | All-swivel carts wander; all-rigid carts cannot steer |
| Floor condition | Rough floors need bigger wheels and softer treads | Small hard wheels on bad floors destroy both |
