  Skateboard wheels   are available in sets of four and also call for eight bearings (offered separately) to properly work. 2 bearings are installed right into each wheel which after that enables it to rotate easily on the axle of a truck. Skateboard wheel dimension is constantly gauged in size by millimeters and the density of a wheel is measured in a durometer on an 'A Range' or 'B Scale' mirroring the solidity of a wheel. 52mm wheels are an excellent starting factor together with an 8" board and also 139, or equal, sized trucks. Nonetheless, wheels can be found in many forms, dimensions, and also colors, and also like every little thing else in skateboarding - individual preference is essential. What dimension wheels should I ride? Skateboard wheel dimensions normally vary from 48mm to 60mm and also various sizes are better suited to particular kinds of skateboarding or surface. Your options in skateboarding devices, as well as hardware, will certainly create wi...

  As the most direct contact part of the skateboard components with the ground, the importance of   skateboard wheels   can be imagined. Because of the most friction loss with the ground, the skateboard wheel is also a component that we often replace. Choosing the right wheels is also extremely important. So what kind of wheel is best for you and your skateboard? When we select wheels in a skateboard store, we can see that the skateboard wheel company will indicate the diameter and hardness of the wheel on the package of each set of wheels. We can use this information to select the appropriate wheel. Wheel hardness (Durometer) The outer packaging of the skateboard wheel is generally marked with words such as 95A, 100A, and 80B, which indicates the hardness of the wheel. The higher the number in front, the harder the wheel. For example, 100A wheels will be harder than 95A wheels. The wheel hardness represented by B will be 20 points greater than that of A, that is to say, ...

  If you compare skateboarding to a person, skateboard wheels are legs, and the importance of wheels in skateboard accessories is self-evident. Whether it is a simple sliding or a trick, the wheels that are in close contact with the ground are always the most worn out, so the skateboard wheels are also parts that need to be replaced frequently. Many novices are worried about when choosing wheels. What does hardness mean? What is the use of different sizes? Material At present, most  skateboard wheels  are made of polyurethane materials. In layman's terms, it is an artificial synthetic rubber. This kind of rubber can change the performance of the wheels by changing the ratio of chemical components to meet the needs of skaters in different scenarios. Each skateboard wheel brand has its own wheel formula, and the difference in formula leads to the different performance of wheels of different brands. Hardness The most common hardness units in skateboard wheels are A (Shore A)...

Caster wheels   come in a variety of materials, sizes, and hardness. The most common materials used to make wheels are rubber and polyurethane. But what's the difference? It helps to understand the relative strengths and weaknesses of each material when determining the best wheel or tread for your particular caster or wheel application. Here are the main criteria you need to consider: Load capacity/maximum weight One of the most important considerations for caster selection may be determining the maximum load. Due to the hardness of the material,  polyurethane casters  usually bear more weight than rubber casters. Furthermore, polyurethane casters have very fine threads compared to rubber casters, which increases their load capacity. Polyurethane casters are also more resistant to splitting and tearing. The floor condition The soft rubber casters are made of carbon black filler and can be marked on the floor. Hard rubber casters are usually grey in color and made of mater...
