Universal conductive wheels are caster wheels in one of many, it is the main features of the work area to eliminate static electricity plant to mute the effect. In some silence and eliminate static electricity to isolated places demanding very strong practicability. Conducting a wide variety of different places caster applications conductive wheels are not the same, we can determine the appropriate conductive caster by the following aspects: 1, the rotation flexibility The larger wheels rotate more effort, roller bearings can carry heavy loads, ball rotation but carrying a lighter and more flexible. 2. Use Going Select large enough to accommodate the cracks round the scene. Also consider using the road size, obstructions and other factors. For wood floors, ceramic tile floors, etc., can be a good choice of super synthetic rubber tire to protect the floor surface, the polyurethane tire suitable for carpet. 3, a special environment Each wheel adapt to different working environment, choose the best to adapt to the particular environment. Traditional rubber not acid oils and chemicals; Hensel tech polyurethane rubber tire casters, plastic wheel, rubber tire and steel wheel modified bakelite can apply various special environment. 4, temperature extremes Bitter cold and scorching heat to many wheels are likely to cause trouble, Kay letter Colson Casters use a special green grease, make casters suitable for -40 degrees Celsius to 165 degrees Celsius. 5, carrying capacity Severity determines the size of the wheel bearing, but also affect the rotation of the wheels, roller bearings for more than 180 kilograms heavier load requirements.     Electronics factory to eliminate or discharge static electricity accumulation, require the use of a conductive casters in assembling the car. Although conductive caster many years ago had come out, but almost all of these conductive wheels will leave marks on the floor. Kay letter provides a super synthetic rubber casters conductive casters solves this problem, this unique design follows the gray super soft elastic conductive synthetic rubber and black conductive adhesive polyolefin core strong, and on the floor without leaving traces.
