On wheels of the 50 series, the contact layer is made of high-quality polyurethane (elastomer), which does not leave any marks at the point of contact with the surface. The wheel base is die cast aluminum. The wheels of this series are distinguished by the best load-lifting characteristics: high load-carrying capacity with a small diameter (saves money), does not have permanent deformation during prolonged downtime in the loaded state; does not cause noise during cargo transportation; has a high resistance to slipping; the presence of a double ball bearing on the wheel axis simplifies movement. They are used on heavy industrial equipment, in mechanical engineering, and in the transportation of glass in production up to 2, 000 kg.
