De RM-Hot-serie combineert hittebestendige wielmaterialen (hogetemperatuurnylon, fenolhars, gietijzer, gesmeed staal) met speciale smeerstoffen en spelingverdragende passingen, zodat de zwenkwiel blijft rollen na thermische cycli.
Standaardwielen falen in ovens door verzachten, loslaten van de kern of vastlopen. RM-Hot-componenten worden geselecteerd voor herhaalde verhitting, niet alleen voor de piektemperatuur.
Specificaties
- Loopvlakopties gewaardeerd van +120 °C tot +280 °C (fenolhars / gietijzer daarboven)
- Hogetemperatuursmeringen voor lagers
- Hittebestendige beugelpassing en grotere loopspleten
- Rem- en zwenkopties getest na thermische cycli
Typische materialen
Hogetemperatuurnylon, fenolhars, gietijzer, gesmeed staal
| Wheel material | Typical hardness | Floor protection | Where it fits |
|---|---|---|---|
| Cast polyurethane (PU) | Shore A 92–95 | Very good: non-marking compounds | AGV/AMR, trolleys on painted or epoxy floors, heavy duty |
| Injected PU | Shore A 90–95 | Good | Cost-sensitive medium duty, light equipment |
| Cast nylon (PA6) | Shore D 70+ | Fair: hard tread | High load, dry indoor logistics, washdown |
| Glass-filled nylon | Shore D 75+ | Fair | Higher loads and temperatures than PA6 |
| Solid rubber | Shore A 65–75 | Good | Shock absorption, outdoor thresholds, economy |
| Super-elastic rubber | Shore A 55–65 | Excellent | Quiet running: medical, hotel, laboratory |
| Phenolic resin | — | Fair | Baking lines and ovens up to +280 °C |
| Forged steel | — | None: needs steel plate or heavy concrete | Extreme loads, heat, harsh floors |
| Stainless (wheel/bracket) | — | Good | Food, pharma, washdown, corrosive areas |
Afwerkingen
Hittebestendige verf of onbehandeld gesmeed
| 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 |
Testen
Thermisch gecycled getest in eigen huis
| 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 |
