Understanding the Types of Castor Wheels Available on the Market
Castor wheels are wheels that are typically mounted to material handling equipment to ensure smooth and unhindered movement of materials and stock. However, it is not just a normal wheel; it is a wheel that is protected by a specialised housing that facilitates the installation of the wheel unit onto other, larger carrying and moving equipment or vehicles. You probably encounter castor wheels in more situations than you realise. They are used on office chairs, kitchen centre islands, workshop benches, hospital beds, supermarket trolleys, and factory equipment. Their load-bearing capacity can vary widely, from 45 kg to as much as 4 tonnes. That is an exceptional range and certainly impressive for those who need to know that they can rely on these wheels to improve productivity and material handling efficiency in a wide range of industrial, commercial, and automotive applications.
When shopping around for castor wheels, you will find that they can be manufactured from various materials, including stainless steel, aluminium, rubber, plastic, polyurethane, aluminium, and cast iron. There are two main types of wheel typically available on the market; swivel castors and rigid castors. Swivel castors can swivel as well as roll due to their design that allows them to pivot around a kingpin. As a result, this wheel can move in multiple directions. It can swivel through 360 degrees, even when under a heavy load. Within the category of swivel castors, there are many variations to choose from. The type of swivel castor wheel chosen will depend on the environment it will be used in and the intended application. These wheel types include plate castors, locking castors, non-kingpin castors, hollow kingpin castors, and stem castors.
Rigid castors are quite different due to their design. They consist of a wheel that is mounted within a fixed frame and it can only roll back and forth, not swivel. Partly because only such limited movement is possible with these castors, they are extremely durable. Although they are rated to carry the same weights as swivel castors in the interest of safety and to discourage overloading of the cart or equipment, it is generally accepted that they can carry a lot more.
Castor wheels’ efficiency, durability, load-bearing ability, and performance depend heavily on their design and there are a number of design components that will affect the overall handling capacity of the castor wheel that you choose. The mount, swivel head, yoke, spring mechanism, wheel, wheel bearings, and the axle bolt and nut will all determine just strong and durable a castor wheel really is over the long term.
Quality is very important when selecting castor wheels. It is vital that the chosen wheel can carry the load and that it will not let you down along the way. Perhaps you need to invest in a whole set of castors or just one to replace a broken or worn wheel; either way, quality should be a top priority for you.
