The Ultimate Guide to Skateboard Bearing Sizes

Skateboard bearings are an essential part of any skateboard, and their size can have a significant impact on your ride. The size of a skateboard bearing is measured in millimeters, and the most common sizes are 608 and 6900. 608 bearings are the most popular size for skateboards, and they are also used in rollerblades and scooters. 6900 bearings are larger than 608 bearings, and they are often used in longboards and cruisers.

Benefits of Using the Right Size Skateboard Bearing

Using the right size skateboard bearing can provide a number of benefits, including:

• Improved speed: Larger bearings roll faster than smaller bearings, so using the right size bearing can help you to improve your speed.
• Reduced friction: Larger bearings have a larger contact area with the axle, which reduces friction and makes your skateboard roll more smoothly.
• Increased durability: Larger bearings are more durable than smaller bearings, so they will last longer and require less maintenance.

How to Choose the Right Size Skateboard Bearing

The best way to choose the right size skateboard bearing is to measure the axle of your skateboard. The axle is the metal rod that runs through the center of your skateboard wheels. Once you know the diameter of your axle, you can refer to the table below to find the correct size bearing.

Stories of Success

There are many stories of skateboarders who have improved their ride by using the right size bearings. Here are two examples:
