Heavy duty swivel plate fitting castor made from a fabricated castor bracket, fitted with two Nylon wheels with precision ball bearings and top hat spacers to prevent over tightening the bearings These swivel heavy duty casters range from 150mm-200mm and have a capacity up to 1500 Kg per caster. Solid Nylon Wheels are less friendly to floors but do offer incredible load capacity compared to many wheel materials. Having a fabricated construction makes then particularly hard wearing and priced competitively. Our heavy duty nylon castors are well suited to heavy duty castor applications for instance lifting equipment , boat cradles and automotive manufactures and suppliers. The black powder coated finish helps protect the heavy duty castors from external. In our experience heavy duty castors must have heavy duty wheels fitted with precision ball bearings to make the most of the heavy duty castor. Precision ball bearings greatly reduce rolling resistance which reduces operator fatigue and prolongs castor life. Nylon wheels are very hard wearing carry very high loads and remain competitive.
