Wheels and casters do a job so basic it's easy to forget they're doing it — they hold the machine up and let it roll where the operator wants it to go. When they're worn, cracked, or seized, the machine fights back. It pulls to one side, wobbles at speed, or takes real effort to steer, and that all lands on your operator's shoulders (literally) shift after shift.
This is the genuine Nilfisk Advance OEM CONTROLLER-MAIN TRIO+HD KIT, part number 56381791, brand new in the box. Genuine replacements keep the machine tracking straight and rolling easy, and they last because they're spec'd for the machine's actual weight and use.
Casters especially wear in pairs — if one is flat-spotted, the other's usually not far behind. Worth checking the whole set when you're in there.
