一、スーツケースのキャスターの種類

There are several types of suitcase wheels, each with different characteristics.

Below, we introduce some common types found in Japan.

■ 1.シングルホイール

The wheels are centrally located on the axle, with suspension on both sides.

The wheels are designed to be thick, providing durability and stable movement on station platforms and airport floors. However, if debris gets caught between the wheel and the housing when pulling the luggage on two wheels, it may accelerate wear.

Single wheels are commonly used in four-wheeled suitcases.

■ 2.ダブルホイール

It's a structure where the center of the axle is supported by a suspension, and wheels are placed at both ends.

With 8 wheels to distribute the weight, it can move smoothly even in crowded stations and narrow passages. It's popular with travelers who prioritize quiet movement and don't want their luggage to get stuck easily.

A double wheel is a structure where the center of the axle is supported by a suspension, and wheels are placed at both ends.

■ 3.キャスターホイール

This type features wheel housings integrated into the suitcase shell and is often used in two-wheeled suitcases. Its large, sturdy wheels make it easy to maneuver in tight spaces, and it's less likely to roll around on its own in places like trains.

Caster wheels, where the wheel housing is integrated into the suitcase shell, are often used for 2-wheel suitcases and duffel bags.

■ 4.インラインスケートウィール

These large polyurethane wheels feature smooth-gliding ball bearings. They are quiet and shock-absorbing, but may add weight.

Inline skate wheels are large, polyurethane wheels characterized by a smooth ride with ball bearings.

■ 5.スピナーホイール

This is a standard feature on 4-wheel suitcases, allowing them to rotate in all directions.

It's convenient for navigating narrow station premises and crowded areas in Japan, and is included in most modern suitcases.

二、ダブルホイールはシングルホイールより優れている？

In Japan, quiet travel by train and bus is valued, so double-wheeled luggage tends to be preferred.

We often receive the question, "Which should I choose, double wheels or single wheels?"

We have summarized the features of each below.

Features of single wheels
These thick wheels offer high durability and move steadily even on station platforms and airport tile floors. Another attractive feature is that they can reduce the overall weight of the suitcase. On the other hand, when pulling them on two wheels, debris can easily get caught, leading to faster wear. Many types do not rotate 360 degrees, so changing direction may not always be smooth.
Features of double wheels
With eight wheels, the weight is distributed, allowing for smooth movement in narrow aisles and crowded places. The design makes them less prone to debris getting caught, and quiet running can be expected, which is another advantage. On the other hand, since the wheels are thinner, there is a slightly higher possibility of damage from strong impacts compared to single wheels, and the suitcase itself may be slightly heavier.

For travel in Japan, where quiet movement on trains and buses is important, double wheels tend to be preferred. However, the smoothness and quietness of the wheels depend more on quality than on type, so we recommend checking the movement and sound of the wheels before purchasing.

三、インラインスケートウィールは通常の車輪より優れている？

Inline skate wheels provide a smooth and stable ride thanks to ball bearings.

Inline skate wheels ensure a smooth and stable ride thanks to their ball bearings.

The wheel surface is made of polyurethane, and its hardness significantly impacts quietness and durability. If it's too hard, the rolling noise will be louder; if it's too soft, wear will accelerate.

In Japan, quietness is particularly valued, so high-quality inline skate wheels are suitable for navigating trains and station premises. However, with cheaper models, the material balance can be poor, leading to louder rolling noise or accelerated wear. They also tend to be heavier, so those prioritizing lightness should be cautious.

Compared to standard wheels, they offer superior smoothness and quietness but come at a higher cost. They are especially recommended for business travelers who travel frequently or those who prioritize quietness. For casual travel, standard wheels are often sufficient.

四、優れたホイールを見分けるポイント

When comparing suitcase wheels, it's easy to get lost in marketing jargon. Below, we'll explain common wheel features and what they mean.

When choosing suitcase casters, it's easy to get confused by marketing jargon. Here are four points you should actually check.

■ 1. 静音性

If the wheel surface has a rubber coating such as polyurethane, it will be quieter and allow for smoother running. At the store, actually roll the suitcase to check the sound. For online purchases, refer to brand descriptions and reviews. However, soft coatings may wear out more quickly, so if you travel frequently, also check the balance with durability.

■ 2. 高品質キャスターの見分け方

Wheels equipped with ball bearings reduce friction and provide smooth movement. In addition, products from high-quality caster manufacturers such as HINOMOTO excel in durability and quietness. However, it's important not to be overly fixated on the manufacturer, but rather to make an overall judgment based on the actual movement and sound.

■ 3. ホイールのサイズ

Wheel diameters typically range from 4 to 8 cm, with 5 to 6 cm being ideal for travel within Japan. Wheels that are too large reduce storage space and increase the risk of damage, so choosing a compact model is more practical.

■ 4. ストッパー付き

Wheels with stoppers are a convenient feature that allows you to secure your suitcase while waiting on trains, buses, or at the airport. Especially on high-speed trains (Shinkansen) or in crowded station areas, they prevent your suitcase from moving unintentionally, which also shows consideration for those around you. Before purchasing, it's a good idea to check whether the lock and unlock mechanisms operate smoothly.

六、スーツケースのキャスターの修理と交換

Silicone and rubber caster covers protect the caster surface and reduce wear and debris buildup.

If your suitcase casters are broken, first check the brand's website or customer service for replacement part availability. Since casters are designed differently for each model, we recommend using genuine parts. Generic replacement wheels often don't match in size or mounting holes, and can affect balance.

For inline skate wheels, DIY repair is possible, but you need to choose wheels with matching diameter and axle size. If repair is difficult, it's safer to ask a specialized store. Specialized websites like minit.co.jp and riat-rs.com are also convenient.

To prolong the life of your casters, we also recommend using caster covers. Silicone or rubber covers protect the caster surface, reducing wear and the accumulation of dirt. Regularly removing dirt and dust from around the casters after use will help maintain their quietness and durability for longer.

To make your suitcase casters last longer, we recommend using "Suitcase Caster Covers".

七、まとめ

Suitcase casters are a crucial factor influencing travel comfort.

While there are various types such as double wheels, single wheels, and in-line skate wheels, ultimately, it's important to choose based on factors that suit your travel style, such as quietness, size, and the presence or absence of a stopper.

Especially in Japan, where quiet movement on trains and buses is valued, it's reassuring to choose products with rubber coatings or from high-quality caster manufacturers. Before purchasing, it's best to physically roll the suitcase in a store to check the sound and movement.

At New Trip, we offer suitcases equipped with casters that prioritize quietness and durability. Please find your favorite travel companion.
