RM-Hot 系列将耐高温轮材（耐高温尼龙、酚醛、铸铁、锻钢）与专用润滑脂及大间隙配合相结合，使脚轮在多次热循环之后依然滚动顺畅。
普通轮子在烘箱中会软化、脱胶或卡死。RM-Hot 的部件按反复加热选型，而不只是按峰值温度选型。
规格参数
- 胎面选项额定温度 +120 °C 至 +280 °C（更高温度用酚醛 / 铸铁）
- 耐高温轴承润滑脂
- 热稳定支架配合与更大的运行间隙
- 刹车与转向选项经热循环后测试
典型材料
耐高温尼龙、酚醛树脂、铸铁、锻钢
| 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 |
表面处理
耐高温喷漆或锻态
| 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 |
测试与检验
厂内热循环测试
| 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 |
