Just acceptable quality: steel bracket is thin a little low load capacity. The caster is not too durable as it has only one ball bearing raceway in swivel head so if overload or by foreign force the bearing ball may fall out.
Same design as the Standard 03S Series but shorter and bigger so it can bear load capacity up to 300 kg. Enhanced PA wheel is strong and durable, it can rolls easy thanks to the double ball bearings. Suitable for lifting heavy machine.
