2X0.5 Pu Caster Wheel, Load Capacity(kg): 500 kg

Product Details

Product Overview A PU caster wheel is a wheel assembly featuring a tread or full wheel made of polyurethane (PU) mounted on a wheel core (steel, cast iron, nylon, etc.) and fitted with a bracket or mounting plate/stem so it can swivel or remain fixed. These are used under trolleys, carts, equipment bases and other mobile industrial or commercial items. Key Features & Construction Wheel Material: The wheel tread (or full wheel) is made from polyurethane (PU), known for its toughness, wear‐resistance, shock absorption and smooth rolling characteristics.  Core / Hub: Often a rigid core (steel, cast iron, nylon/plastic depending on duty) to give structural support, with the PU bonded or molded to it.  Bracket / Mount: Usually a swivel or fixed bracket, often top plate or bolt‐hole type, sometimes stem or pin type. Can have brakes or locks depending on configuration.  Hardness & Specifications: PU tread hardness often in the range of Shore A 90–95 for heavier duty.  Sizes & Load Ratings: Available in a wide range of diameters (for example 75 mm, 100 mm, 125 mm, 150 mm, 200 mm etc.) and load capacities—from medium duty (100–200 kg/wheel) to heavy duty (1000 kg+ per wheel) depending on size and construction.  Performance & Benefits Low Rolling Resistance & Smooth Operation: Because of the polyurethane, the wheel rolls smoothly with less effort and less noise.  Floor Protection / Non‐Marking: PU typically does not mark or scuff flooring (tiles, polished concrete, wood) and is gentler on surfaces compared to harder materials.  Durability & Wear Resistance: PU is abrasion resistant, withstands frequent movement, and holds up well over time.  Chemical / Oil / Environmental Resistance: Resistant to many oils, greases, mild chemicals; can operate in a wide temperature range and under industrial conditions.  Shock & Vibration Absorption: Better shock absorption compared to harder wheels, reducing transmitted vibration to equipment.  Typical Applications Warehouse & industrial trolleys, material‐handling carts Factory equipment, machinery bases Medical carts, hospital beds where quiet / non‐marking floors matter Retail equipment, display stands Clean rooms, logistics areas, freight movement Specification Example Template Wheel diameter: e.g., 100 mm Wheel width: e.g., 32 mm Tread material: Polyurethane, hardness ~90 Shore A Core material: Steel/nylon hub Mounting: Swivel bracket with top plate (75 × 50 mm) Load capacity: e.g., 300 kg dynamic, 360 kg static (for one wheel) Bracket finish: Zinc‐plated or stainless steel (for corrosive / clean environments) Temperature range: approx. –20°C to +80°C (subject to manufacturer)  Additional features: Non‐marking tread, ball bearings in swivel head, option for brake lock
