Unlike screw on wheels, casters are not driven by an engine. They are mounted to the bottom of a larger object, making it easier to move and transport groups of items. Casters are used in a wide variety of applications, from furniture and workstations to industrial equipment and assembly lines. They are also used for toy wagons and shopping carts.
Who built the first wheel?
There are a number of different casters available, each with its own set of features and benefits. Choosing the right casters is important for maximum productivity and safety. The best casters should be rated for a higher capacity than the load.
The material that a caster wheel is made of plays a big part in its weight capacity. For lighter loads, rubber and plastic are the ideal materials. They are durable, easy to roll, and are perfect for outdoor surfaces.
Wheels are also available in a variety of materials, from rubber to steel. Rubber tires provide smooth rolling, but can leave marks on floors.
Polyurethane wheels are perfect for medium-duty loads. They are resistant to shock, abrasion, and rust. They also have non-marking properties. They are also designed to resist abrasion and cracking.
Alternatively, casters may be made of steel or aluminum. They are durable and come in various sizes. They are also resistant to grease and oils. For heavy duty applications, forged steel wheels provide extra load capacity. They also offer greater impact strength.
The type of caster mounting also plays an important role. Some types of casters can be fixed to roll along a straight path, while others can swivel.
