Electrically conductive wheels and antistatic wheels and castors are used in almost every industrial setting, from medical engineering, electrical and semi-conductor industries to the automotive industry, hospitals, pharmaceuticals and other chemical industrial sectors. These wheels and castors are used everywhere protection against electrostatic discharge is required. Operators and sensitive goods are particularly susceptible to the electrostatic discharge that can be generated by transport units or by transported goods.

Compact castors combine a particularly impressive load capacity with a low mounting height. Some of these castors can support loads of up to 700 kg, with a total height of just 112 mm. Compact twin castors can handle even more: up to 1750 kg with a total height of just 125 mm. They are perfectly suited for reducing the risk of tall and heavy furniture tipping over due to a high centre of gravity. That’s why they are frequently used for server racks or control cabinets. Compact castors are the first choice when significant load capacities are required despite space being at a premium, such as under a hospital bed.

The SVS wheel series is primarily used for heavy duty applications requiring extremely high load capacities of up to 15,000 kg. They are typically used in machine and systems engineering. Their resistance to a wide range of aggressive substances also makes them suitable for use in applications which require resistance to chipping and oil. Despite their exceptional load capacities, only minimal effort is required on smooth surfaces to move transport units with SVS castors. The rugged grey cast iron series is extremely wear-resistant and is also capable of withstanding temperatures of between -25°C and 120°C.

Blickle cast iron wheels are made from robust grey cast iron with a hardness of 180 to 220 HB. They are extremely wear-resistant and provide very little rolling and swivel resistance. Cast iron wheels are self-lubricating due to the graphite which they contain. However, they should always be sufficiently lubricated using the grease nipple, particularly when using the plain bore version. Due to the relatively high level of floor pressure, care must be taken when using this wheel series on sensitive surfaces. The silver coating on the wheels can change colour at high temperatures, but this does not affect the corrosion protection provided by the coating. Standard cast iron wheels are designed for use in temperatures of up to 120°C.
