Electrically conductive and antistatic wheels and casters from Blickle

Electrically conductive wheels and casters are important system components in almost all industrial sectors from medical engineering, electrical and semi-conductor industries, to the automotive industry, to hospitals, pharmaceuticals, and other chemical industrial sectors. They are also indispensable in explosion protection zones.

The electrical conductivity of wheels, swivel casters, and fixed casters protects against electrostatic discharge that can be generated by transport equipment or by transported goods. The use of ESD wheels and casters prevents painful electrostatic discharges to the truck user or damage to fragile transported material.

The Blickle product range contains a variety of different wheel series which can also be provided in an ESD design. Alongside rubber, plastics, and metals, polyurethane is also available in a dissipative version as tread material. All products are made in line with the "Made in Germany" quality standard, which also means there is great flexibility with regards to special requests.

A wheel or a castor is considered to be electrically conductive in line with standards for wheels and casters (DIN EN 12530 - 12533) if its ohmic resistance does not exceed 104 Ω (product code suffix: -EL or -ELS). A wheel or a caster is regarded as having antistatic properties if its ohmic resistance does not exceed 107 Ω (product code suffix: -AS).

To guarantee such requirements, Blickle tests electrically conductive wheels on a special test bench in line with DIN EN 12527. Measurements take place on 3 different locations on the wheel's tread. This ensures that even in critical applications, any electrostatic potentials that may occur can be safety dissipated via the wheels and casters used. Dirt accumulating on the tread or other environmental influences can have a negative effect on the conductivity during operation and this should be checked by the operator regularly.
