Suitcases are essential items for travel and business trips. Their ease of use is greatly affected by their "casters."

However, casters can be a surprisingly troublesome part, getting scratched or dirty during transit, or making loud noises. "Caster covers" can solve these problems.

 

This time, we will thoroughly introduce everything from how to choose caster covers for suitcases to recommended products.

What are the benefits of using caster covers?

Attaching caster covers will dramatically improve the usability and lifespan of your suitcase.

The main benefits are as follows:

Improved quietness and increased durability

Silicone caster covers absorb friction and impact during travel, significantly reducing unpleasant rattling noises. You'll particularly notice their effectiveness when moving at night or in quiet areas.

They also help prevent direct damage to the casters themselves, reducing wear and tear and extending the lifespan of your suitcase.

Title

Stability and slip resistance

Suitcase caster covers, especially those with an uneven, tire-pattern design on their surface, offer high anti-slip performance. This is very effective in improving the stability of suitcases in unstable environments such as cobblestone streets, gravel roads, places with many steps, or wet surfaces.

Title

Maintenance becomes significantly easier.

 Casters that roll outdoors inevitably get dirty with soil, sand, dust, and so on. With a caster cover, simply remove and rinse the cover when it gets dirty. This eliminates the hassle of directly wiping the main unit's casters, making it easy and hygienic to maintain.

Title

Uniqueness and Findability

The rich color variations are also one of the attractions of suitcase wheel covers. Even a simple suitcase can be given a unique look by attaching a cover in your favorite color. This also has the effect of making your suitcase instantly recognizable in places where many suitcases are lined up, such as airport carousels, thus preventing mix-ups.

6 Tips for Choosing Caster Covers

To choose the perfect caster covers for your suitcase from the many available options,

pay attention to the following points:

Title

to match the diameter of the caster

Most importantly, choose a size that matches the diameter of your suitcase's wheels. The size of the wheels varies depending on the size of the suitcase, with 49mm-55mm being common for S/M sizes, and around 60mm for L sizes. If the size doesn't match, the cover may come off while moving, or conversely, it may be too tight to attach, or it may hinder smooth movement. Be sure to measure the diameter of your suitcase's wheels before purchasing.

 

・Important point: Some products cannot be attached if the gap between the wheel and the support part is too narrow, not just the gap between the wheel and the axle, so it is recommended to carefully check if it fits your carry-on case.

Title

"Side" length (thickness) of the cover

Suitcase wheel covers with long sides (approximately 1-1.5cm) tend to fit snugly on the casters and are less likely to come off while in motion. Some inexpensive products have shorter side protection, but if stability is a priority, it's a good idea to check the length of the sides.

Title

Ease of attachment/detachment

Caster covers include:

 

・Easy-to-remove silicone ring type

・Tape type that once applied, is not removed

・Sock type specializing in preventing indoor dirt

 

If you want to attach and detach them routinely, stretchable silicone is convenient.

Title

Surface shape (tread pattern)

The surface of suitcase wheel covers can be either smooth and flat, or they can have a tread pattern like a tire.

 

・If you prioritize smooth movement on flat surfaces → choose a flat one.

・If you seek some grip and shock absorption → it's advisable to choose one with a tread pattern.

 

A tread pattern can also offer better noise reduction.

Title

Design and Color

As mentioned earlier, color not only expresses individuality but also makes it easier to spot your luggage. Choose a caster cover in your favorite color or design to enhance your travel experience.

Title

Indoor Cleanliness Measures

Some people may be concerned about dirty wheels when bringing their suitcase indoors. In such cases, we recommend using a sock-type cover over the suitcase wheel covers. This will prevent dirt and dust from the wheels from being brought into the room.
