Skateboarding can be harsh on bearings due to impacts and dirt from surfaces, which can damage them and affect performance. Additionally, noisy, rattling bearings can be distracting. Therefore, regularly replacing bearings is a good practice to keep your skateboard in top condition and ensure smooth wheel rotation.

Typically, bearings are made from chrome steel and are available in grades 1, 3, 5, 7, and 9. The higher the grade number, the more accurate and precise the bearing. ABEC-5, ABEC-7, and ABEC-9 bearings are commonly used in skateboards. Some brands offer ceramic bearings, which are more expensive but provide superior performance and require less maintenance. Ceramic bearings do not rust, which significantly extends their lifespan compared to steel bearings.

Skateboard bearings are crucial components of skateboards, situated inside the wheels. They allow the wheels to rotate smoothly. Each wheel is fitted with two bearings, so a complete skateboard requires eight bearings. The standard dimensions for skateboard bearings are 8mm for the core diameter, 22mm for the outer diameter, and 7mm in height.

There are various types of bearing packaging available, such as plastic tubes, plastic boxes, six-grid cases, paper boxes, wooden boxes, metal boxes, and more.

Skateboard bearings consist of several components: the bearing shield, inner and outer rings, bearing balls, and ball retainer.

Bearing shields can be made of metal or rubber and come in various colors. They can also be customized with different logos.

When selecting skateboard bearings, consider the following factors: precision (grade), lubrication, material, and the bearing shield. For street skating, an ABEC-5 bearing is typically sufficient. For vert skating, it might be beneficial to use ABEC-7 or ABEC-9 bearings to optimize speed and achieve enough air time for tricks. It's also important to note that not all brands use the ABEC scale to measure bearing precision.
