Whether you’re looking to buy a heavy-duty wheelchair or need to roll your wheelchair or stroller, you’ll need to learn about rigid casters. Several casters include swivel, stainless steel, smooth-stem, and threaded-stem casters.

Swivel vs. rigid casters
Choosing the correct caster type depends on several factors, including the size of your cargo and available space. Both rigid casters and swivel casters are available in various designs, sizes, and materials. In addition, some of these casters come with brake mechanisms, which can be helpful when moving heavy loads.
Swivel casters are generally used to move pallets and other materials around and are commonly used to carry heavy loads in warehouses. Swivel casters are installed on ball bearings and rotate 360 degrees. As a result, it can be challenging to maneuver long straight distances.
Rigid casters, on the other hand, move heavy materials in a straight line. They are also more substantial than swivel casters. These casters are often bolted or riveted to equipment. They are available in a two-piece or one-piece construction. They are suitable for heavy loads and can be used with swivel casters to offer better maneuverability.
Larger diameter wheels roll more smoothly
A giant-diameter caster wheel can reduce the effort required to roll a load. It means that it can be more productive, less tiring, and can even help prevent accidents.
Larger wheels can also improve performance on rough surfaces. For example, they can roll over trash and depressions better than their smaller counterparts and not bog down on mats or carpets. In addition, it helps to reduce employee fatigue.
Aside from the obvious, larger wheels can also provide more load capacity. It can help maximize the storage space in mobile cabinets. Some casters even have a load rating of 500 pounds.
Rolling resistance is also an important consideration. A large wheel has a more important center of gravity, which helps to distribute weight over a wider area. As a result, it is great for rolling on uneven surfaces, but it can be troublesome on smooth floors, especially with slight slopes.
A study conducted by Frank and Abel measured the rolling resistance force of several different front caster sizes. They found that a caster wheel with a diameter of 4 inches produced the highest roll-through-time (RTT) and drag energy.
Twin-wheel casters
Designed with a patented parabolic wheel face, TWERGO(r) heavy-duty casters feature a 3-in-1 wheel configuration that minimizes friction and force needed to maneuver. In addition, these casters eliminate the “scrubbing” effect of wide tires on smooth floors. They also feature aluminum die-cast cores and robust spanners to achieve unparalleled ergonomic benefits.
In addition to the benefits of these casters, the swivel action is improved, and the overall height is reduced. As a result, these casters can be used in various applications, including furniture and T.V. stands. They can also transport heavy equipment, scientific equipment, and other material-handling equipment.
These casters are available in a variety of dimensions. The dimensions may be altered without interfering with the robust resistance to oscillation.
The size of the wheels should be selected to match the floor surface. Wider tires may cause rubbing problems, depending on the suspension and lowered height of the application. They may also increase the risk of rim drop, which can endanger humans and trailers. On the other hand, the larger-diameter wheels are also more rollable. Therefore, it can be beneficial in applications with specific standover heights.
Stainless steel vs. smooth stem vs. threaded stem
Whether you need to replace a caster or are just interested in purchasing a new one, you should be familiar with the differences between stainless steel vs. smooth stem vs. threaded stem on rigid casters. This article will walk you through the differences and help you make the best choice.
Stem casters are generally used for lighter-duty applications. They can be replaced quickly. They are available in various sizes, styles, and features. These casters are designed to reduce strain on the back and feet while moving items around.
Threaded stem casters are designed to be sturdy and easy to replace. They are usually attached to the item with a bolt, heavy nut, and washer. Pipe frames are only one of the many applications they may be put in. A caster buying guide is a wise option if you need clarification on which kind is ideal for your application.
