Casters and wheels are vital pieces of equipment that improve workplace efficiency by allowing people, products and loads to move faster across/throughout any environment. They reduce the risk of workplace injuries by reducing the amount of force required to move heavy objects.
A wheels and casters is an assembly of a wheel unit, which is affixed to an object, and fasteners that connect the frame to the object. This wheel unit is called the caster yoke or caster fork and has nuts and bolts that allow the wheel to move, shift or turn.
The caster yoke can also have additional hardware fittings to keep the caster in place and secure. In most cases, these hardware fittings are made of a durable material that will hold up against the harshest conditions.
Wheels and Casters: What You Need to Know
The wheel that a caster has on it is the primary distinguishing feature, but the materials and dimensions of the wheel can have an impact on how easily the caster can roll, as well as its durability and noise level. There are numerous types of caster wheels and the proper type for an application is dependent on factors like floor condition, load, speed and climate.
Ferrous – The strongest of all the caster wheel options, this steel wheel is ideal for rough surfaces, heavy loads and applications with high impact and chemical resistance.
Synthetic – A number of different synthetic tread materials can be used on caster wheels, including elastomer (rubber and polyurethane), phenolic and solid nylon. These harder-tread materials have lower rolling resistance than softer-tread alternatives and offer greater durability.
