Two component solid rubber tyre, roller bearings, wheel x width 125 x 37.5 mm. Supplied = assembled. Structure = wheel. Wheel material = semi-elastic solid rubber. Material of rim = sheet steel, galvanised. Wheel diameter = 125 mm. Max. load at 4 km/h = 120 kg. Wheel width = 37.5 mm. Wheel bearing = roller bearing. Temperature resistance = -25 C to +80 C. Hub length = 45 mm. Hub bore = 15 mm. Shore hardness = 65 A. Product type = wheels. On sheet steel rims. Very smooth running. Non-marking. Hardness 65 Shore A. Temperature resistant from -25 C to +80 C. Rims made of sheet steel, electrolytically zinc plated and blue passivated. Tyres made of two-component solid rubber with hard tyre bed and highly elastic running surface, black. In comparison to solid rubber, increased load capacity and smoother run with less rolling resistance.
