Two-component solid rubber tires with a wheel diameter of 200 mm and a width of 50 mm, featuring a fixed castor. They are mounted on a sheet steel rim, providing very high driving comfort and being gentle on the floor. The hardness is 65 Shore-A, and they are temperature resistant from -25 °C to +80 °C. The sheet steel housing and rims are electrogalvanized and blue passivated. The swivel bearing includes a double ball race, ensuring smooth running with minimal play. The tires are made of two-component solid rubber, featuring a hard tire base and a highly elastic tread in black. Compared to solid rubber, these tires offer increased load capacity and ride comfort with reduced rolling resistance. They also include roller bearings.
