Poliuretana adalah pilihan bawaan saat Anda membutuhkan kapasitas beban mendekati nilon tetapi harus melindungi beton yang dicat atau lantai epoksi. RollMaster melakukan casting roda PU secara internal pada inti besi abu-abu dan baja.
Roda PU menawarkan hambatan gulir rendah, cengkraman baik, laju senyap, serta ketahanan terhadap oli dan banyak bahan kimia — roda standar untuk platform AGV/AMR dan penanganan material dalam ruangan.
Spesifikasi
- Kekerasan Shore 92A–95A standar, senyawa lain sesuai permintaan
- Lini produksi PU injeksi dan cor di internal pabrik
- Tersedia senyawa abu-abu dan merah yang tidak meninggalkan bekas
- Rentang suhu umumnya -20 °C hingga +80 °C
Finishing
Braket berlapis seng atau baja tahan karat
| 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 |
Pengujian
Daya lekat PU-ke-inti dan kekerasan diperiksa 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 |
