Wheel:

• heat-treatable steel, machined, hardness 190–230 HB
• slightly crowned tread
• lightly-oiled surface
• extremely low rolling resistance
• easy operation on smooth surfaces
• outstanding wear resistance
• extremely high static and dynamic load capacity

Other features:

• chemical resistance to many aggressive substances
• operating temperature: -20 °C to +120 °C
• consider the surface pressure on sensitive floors due to high point loads

• electrical conductivity (ohmic resistance) ≤ 10⁴ Ω
