What is the use of caster wheel?
A caster is an assembly that includes a wheel and a mount. Casters support and make it easy to maneuver carts, racks, dollies and other equipment . Casters come in different materials, wheel diameters, tread widths, load ratings and overall heights to give your equipment mobility in many kinds of work environment.
How does a caster work?
Caster causes a wheel to align with the direction of travel , and can be accomplished either by caster displacement or caster angle. Caster displacement moves the steering axis ahead of the axis of wheel rotation, as with the front wheels of a shopping cart. Caster angle moves the steering axis from vertical.
What is the difference between a castor and a wheel?
The wheel is limited in that it only spins on a single axis . It can only roll in one direction at a time. Casters incorporate wheels into their designs, but they are a bit more sophisticated. A caster includes the mounting system that holds the wheel in place.

What happens if you have too much caster?
Caster settings are not a primary, direct factor in tire wear . However, excessive positive caster in association with other alignment maladjustments can exacerbate a tire wear issue. For example, a tire wear pattern called feathering can result from a combination of too much caster with incorrect toe settings.
Do cars have positive or negative caster?
Modern cars use positive caster in order to resist unintentional turning of the vehicle, or wandering/straying from the intended path, when traveling straight at speed. A car that pulls to one side when traveling in a straight line may have negative caster.

WHEEL SIZE NOT only affects a car’s performance but it also has an impact on noise levels, comfort and fuel economy . As tyre sidewall height decreases, performance tends to get sharper and handling usually improves too. Lap times also seem to improve but not massively so.
How do you choose casters?
Generally, the greater the weight , the larger the wheel required for the caster. Larger wheels distribute weight and roll more easily over floor obstructions. To determine the load capacity for each caster, divide the combined weight of the equipment and maximum load by the number of casters to be used.
What are glides used for?
