A castor wheel is a wheel unit affixed to an object, which then helps the object move. There are two major types of caster wheels: swivel and rigid.
Swivel casters pivot around a kingpin, allowing them to turn and roll. This type of caster is often used on hospital beds and stretchers because it allows for smooth movement over surfaces.
Rigid casters have their wheel mounted in a frame, or rig, that allows them to move and shift. These casters are typically found in industrial and commercial settings.
Casters can be made of several materials, including cast iron, steel, and aluminum. Choosing the right material for your specific application is important to ensure the wheel will be able to withstand the weight and wear of the equipment you are moving.
The Ultimate Guide to Castor Wheels: Everything You Need to Know
Solid caster wheels are unbreakable in normal use, can withstand high temperatures, and can absorb shock without failure. They are also more durable than ductile steel casters and can be used in a wide range of environments.
Forged caster wheels are made from forged steel and provide greater load capacity, impact strength and rollability than ductile steel casters. They are designed to withstand harsh environments, like warehouses and manufacturing factories.
Medical caster wheels are especially useful in hospitals and other health care facilities because they are durable, smooth-rolling and easy to clean. They can handle a variety of floor conditions, including water-clogged floors and mild chemicals.
Regular lubrication and maintenance are necessary to keep the bearings in good working order. This is best done by reapplying lubrication about every six months, depending on usage, humidity and chemical exposure.
