Swivel castors with a black fabricated castor bracket fitted with a heavy duty high temperature resistant wheel roller bearing centre wheel working temperature (- 45 to 120 Celsius) . These swivel casters range from 150mm - 200mm and have a capacity up to 500Kg per caster. The load carrying capability of our high temperature resistant wheel is much higher than normal similar wheels materials . They have a hard tread useful for heavy applications where the equipment is often subject to a hard working environment. They offer a low rolling resistance when compared to traditional hard tyred castors. Very important to remember this is a premium high temperature resistant wheel l not to be confused with other lower grade alternatives which make claim to similar loads and rolling resistances which are incorrect. Ideal for waste bins, power coating , some food application and where abuse is likely. They resist water, grease, animal fats and most acids and alkalies. They are lightweight, easy to roll and will not mark floors.
