Ruedas conductoras y antiestáticas

Antistatic conductive caster with a dark conductive rubber wheel

Las ruedas conductoras disipan las cargas estáticas a través de la banda hacia el suelo, protegiendo PCBs, obleas y procesos de manipulación de polvos; las mezclas antiestáticas evitan la acumulación peligrosa de carga en carros y estanterías.

Los valores de resistencia se miden por lote y pueden documentarse por entrega.

Especificaciones

  • Mezclas de PU y goma conductoras con resistencia superficial medida
  • Informes de ensayo de resistencia disponibles por lote
  • Compatibles con sistemas de suelo ESD
  • Opciones de horquilla en acero y acero inoxidable

Materiales habituales

PU conductor / goma conductora sobre núcleos conductores

Wheel materialTypical hardnessFloor protectionWhere it fits
Cast polyurethane (PU)Shore A 92–95Very good: non-marking compoundsAGV/AMR, trolleys on painted or epoxy floors, heavy duty
Injected PUShore A 90–95GoodCost-sensitive medium duty, light equipment
Cast nylon (PA6)Shore D 70+Fair: hard treadHigh load, dry indoor logistics, washdown
Glass-filled nylonShore D 75+FairHigher loads and temperatures than PA6
Solid rubberShore A 65–75GoodShock absorption, outdoor thresholds, economy
Super-elastic rubberShore A 55–65ExcellentQuiet running: medical, hotel, laboratory
Phenolic resin—FairBaking lines and ovens up to +280 °C
Forged steel—None: needs steel plate or heavy concreteExtreme loads, heat, harsh floors
Stainless (wheel/bracket)—GoodFood, pharma, washdown, corrosive areas

Selection factorRule of thumbEffect on performance
Load sizingTotal load ÷ 3 (not ÷ 4)On uneven floors only three wheels carry the cart
Wheel diameterBigger rolls easierLarger wheels cut push force and bridge gaps
Tread hardnessSofter = quieter, harder = easier rollingPick the softest tread that carries the load
Bearing choicePrecision ball for manual pushing, roller for heavy loadsBearings dominate rolling resistance at high load
Swivel vs rigid2 swivel + 2 rigid is the standard cart setupAll-swivel carts wander; all-rigid carts cannot steer
Floor conditionRough floors need bigger wheels and softer treadsSmall hard wheels on bad floors destroy both
