CASTORS - WORKING OUT YOUR LOADING
To calculate the safe working load (SWL) for each castor take the weight of load in kilograms and divide by the number
of castors minus one, e.g. 100kg divide by 3 (4 wheels minus 1) = 33kg. So each castor should accommodate a safe
working load of 33.3kg or greater.
NYLON VERSUS POLYURETHANE
When making the choice between nylon and polyurethane wheeled castors the usage has to be considered.
Polyurethane is for heavy duty applications where a lot of weight is being carried.
Nylon will not mark and is generally used for lighter domestic-type applications.
