Skateboard bearings dimensions
Skateboard bearings typically follow the standard size known as the “608” bearing. Here are the dimensions:
1. Inner Diameter (ID): 8mm
2. Outer Diameter (OD): 22mm
3. Width (W): 7mm
These dimensions are standard across most skateboard bearings, allowing them to fit into skateboard wheels of various brands and designs.
Skateboard bearings typically follow the standard dimensions of the ABEC (Annular Bearing Engineering Committee) ratings, which are measured in millimeters.
The most common size for skateboard bearings is 8mm (inner diameter) x 22mm (outer diameter) x 7mm (width).
These dimensions are standardized across most skateboard bearings, but there may be variations in certain brands or models.

These dimensions are standardized across most skateboard bearings, but there may be variations in certain brands or models.
Beyond these basic dimensions, skateboard bearings are often classified by their ABEC rating, which indicates their precision and tolerance levels. The higher the ABEC rating, the tighter the tolerances and the smoother the bearing rotation. However, it’s important to note that ABEC rating isn’t the sole factor determining the performance of skateboard bearings. Other factors like material quality, lubrication, and design also play significant roles.
Skateboard bearings are typically sold in sets of eight, as each skateboard requires a set of two bearings for each of its four wheels. When purchasing bearings, it’s essential to ensure compatibility with the skateboard wheels and axles to ensure smooth and efficient performance while riding.
In addition to the standardized dimensions and ABEC ratings, skateboard bearings often feature a shield or seal design to protect the internal components from dirt, debris, and moisture. These shields can come in various forms, including metal shields, rubber seals, or a combination of both.
Metal shields, typically made of steel, offer strong protection against external elements but may slightly increase friction and reduce speed. On the other hand, rubber seals provide excellent protection while maintaining smoothness and speed, but they may wear out more quickly over time.
Some skateboard bearings also incorporate features like removable or non-removable inner raceways, which can affect the ease of cleaning and maintenance. Removable inner raceways make it easier to clean and lubricate the bearings, while non-removable ones require more care during cleaning.
Ultimately, the choice of skateboard bearings depends on individual preferences, riding style, and budget. Whether you’re a casual rider or a serious skateboarder, selecting the right bearings can significantly impact your overall skateboarding experience in terms of speed, durability, and performance.
