슈퍼 엘라스틱 그레이 고무는 솔리드 고무나 나일론보다 눈에 띄게 조용히 구르며, 매우 낮은 힘으로 굴러가고 출입문 턱과 이음줄을 완충합니다.
의료 카트, 실험실 기기, 호텔 트롤리, 그리고 소음이 문제 되는 모든 실내 환경의 표준 휠입니다.
사양
- 슈퍼 엘라스틱 그레이 고무, 논마킹
- 연질 트레드에도 매우 낮은 구름 저항
- 정밀 저소음 베어링 표준 사양
- 캐스터당 40~300 kg 하중
대표 재질
강철 / PP / 알루미늄 코어 위 슈퍼 엘라스틱 고무
| 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 |
표면 처리
아연 도금 또는 스테인리스 브래킷
| 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 |
시험
배합재 배치별 소음 및 구름 저항 비교
| 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 |
