Typical swivel caster. A caster (also castor according to some dictionaries) is a wheeled device typically mounted to a larger object that enables relatively easy rolling movement of the object. Casters are essentially special housings that includes a wheel, facilitating the installation of wheels on objects.
The caster is the amount by which a steered wheel trails behind the vertical axis about which it is steered. Positive caster projects the load of the vehicle to a point on the road ahead of the tire contact. If the caster angle is too large, it will cause heavy steering and the driver will quickly get tired. Negative caster helps to center the steering wheel after a turn, and makes the front tires straighten quicker.
