Swivel castors with a black fabricated castor bracket fitted with a heavy duty ball bearing centred cast iron wheel. These swivel casters range from 100mm-200mm and have a capacity up to 500 Kg per caster. Cast Iron Wheels are less friendly to floors but do offer incredible load capacity compared to many wheel materials. They are strong and very hard wearing and priced competitively. Typical application steel fabrication trolleys , waste bins and steel handling equipment. The black finish is not standard we decided to produce our LMH series castors in black to provide a material finish which was hard-wearing. The precision ball bearings improve rolling resistance and reduce stresses which can cause premature castor failure. We recommend our LMHB series castors if your application requires strong heavy duty castors at a price sensitive point.
