Castors are mounted to the bottoms of furniture, equipment, or industrial materials handling equipment such as trolleys, to enable them to move easily and smoothly.

A castor consists of a wheel that rotates around a central axis, attached to a mounting plate or stem which is then attached to the object. The mounting plate or stem may also include a swivel mechanism, which allows the castor to rotate and pivot in any direction, making it easier to manoeuvre the object.

Castors allow heavy or bulky objects to be moved more easily and with less strain on the user's back and arms. They also allow objects to be repositioned quickly and efficiently, which can improve productivity and efficiency in a variety of settings.

Castors can also help to protect floors from damage by distributing the weight of objects more evenly and reducing the amount of friction between the object and the floor. Some castors include locking mechanisms that can be used to keep the object in place when it is not in motion.
