Castors used indoors, in warehouses, factories etc., are restricted by necessity to about 10 kmph. But even at this slow speed, both the wheel and the castor can suffer severe impacts from uneven surfaces. The castors and wheel chosen must be strong enough to cope with this.Outdoor use can be even more severe.
