Skateboard Bearing 608 Bearing

‌Skateboard bearings‌ are an important part of skateboards. Their main function is to connect the wheels and brackets to ensure that the wheels can rotate smoothly. The design and material of skateboard bearings have an important impact on their performance.

Basic components of skateboard bearings
Skateboard bearings are composed of the following main parts:

Seals: Prevent dust and other debris from entering the bearing to extend its service life.
‌Rolling element‌: Usually steel balls or ceramic balls, each set of bearings contains 7 rolling elements.
‌Cage: Separate the rolling elements evenly to prevent them from falling off.
‌Inner and outer rings‌: The inner and outer rings provide grooves for the rolling elements to roll.

Materials and types of skateboard bearings
Skateboard bearings are mainly made of two materials: metal and ceramic. Metal bearings are usually made of bearing steel, which is cost-effective but has poor rust resistance; stainless steel bearings have good rust resistance, but are more expensive; ceramic bearings are composed of ceramic balls and metal shells, which have self-lubricating functions and high wear resistance, but are the most expensive.

Grades and selection criteria for skateboard bearings
The grades of skateboard bearings are usually expressed in ABEC (Annular Bearing Engineering Committee) standards, from ABEC-1 to ABEC-9. The higher the grade, the higher the precision and speed. However, the ABEC rating standard does not take into account factors such as impact force and side-slip torque in skateboarding, so some skateboard companies do not use the ABEC standard.

Care and maintenance of skateboard bearings
In order to keep skateboard bearings in good condition, they need to be cleaned and oiled regularly. When cleaning, remove the bearings from the wheels, wipe off the oil and stains with a paper towel, and clean them once a week. Oiling is required after cleaning. You can use cooking oil or special lubricants, and avoid using corrosive liquids such as gasoline.

In summary, skateboard bearings are not only key components of skateboards, but their materials, grades, and maintenance methods will directly affect the performance and user experience of skateboards.
