Caster is the angle of a line drawn through the upper and lower steering pivot points, which affects the steering effort and directional control of your vehicle. It’s a relatively unknown but extremely important adjustment that can have an enormous impact on how your car handles and corners.
Generally, castor wheels is set to be positive (or a negative camber) in the front of the car to make the steering easier to control and improve straight-line stability at high speeds. However, this can cause the car to lurch or wander to the side, which can be dangerous for both passengers and the driver.
Negative caster can also help the car handle better on the track by making it more stable and predictable in the turn. This also helps keep your tires in contact with the road and creates a more consistent tire patch when drifting, which can increase grip.
Common Issues with Caster Wheels and How to Avoid Them
Wheel caster comes in many different shapes, sizes and materials. Some casters are designed to be more durable and load bearing than others, so choosing the right one for your application is crucial.
Industrial casters can be made from steel or stainless steel, and are ideal for moving heavy equipment that is typically subjected to harsh chemical, steam and caustic cleaning agents. They can also be used in food service and processing plants for light to medium loads.
Rigs come in rigid and swivel forms, so you can choose the type that best suits your needs. Rigid rigs limit the wheel’s movement to a straight line, while swivel rigs allow the wheel to rotate in 360 degrees.
