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.

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.

Besthane® treads have 40% lower rolling and swivel resistance than the other polyurethane treads. This means that much less force is required to push or pull transport units carrying heavy loads. It also makes the series particularly interesting for customers focused on ergonomics and occupational safety. Besthane® tread also provides a particularly high level of dynamic load resistance, which is particularly useful when transporting sensitive materials. The tread is typically used for a variety of heavy duty applications on different transport units and machines in the machining and automotive industry. It can provide a load capacity of up to 12,000 kg at high speeds of up to 16 km/h.
