Most of the current skateboard wheels are made of petrochemical product polyurethane (polyurethane), which has good elasticity and can be made into various colors. At first, the wheels were made of rubber, UHWMPE plastic, clay, and even metal. Fortunately, these have become a thing of the past. The following skateboard wheel manufacturers will come to analyze with you!
Polyurethane wheels can achieve a diameter of 99mm, but the board surface is too low and the use of a movable bridge may cause a wheel bite phenomenon. The contact width refers to the width of the wheel in contact with the ground when sliding. The wider the grip, the better the grip performance, and it is not easy to slip or wear locally. Narrow wheels are not strong and easy to slip, and are prone to wear or partial wear due to excessive pressure.
The shape of the wheel affects the sliding effect. There are three main factors: wheel diameter, contact width and side shape. Wheel diameter is very important. Generally speaking, the big wheel slides faster, while the small wheel accelerates faster, because the small wheel starts with little resistance and the large wheel slides faster at the same speed. At a certain sliding speed, the bearing wear caused by the increase of the rotation speed of the big wheel is smaller, especially for the long plate. The big wheels glide faster on rough roads, and the difference of a few millimeters can make a big difference. The road surface can be seen as composed of many tiny stone obstacles relative to the wheels. The outer diameter of the wheel can be selected according to the road conditions. The larger the wheel diameter, the stronger the ability to pass obstacles, but this is not the same thing as crossing obstacles on smooth surfaces such as skate parks. .
