Ultimate Guide to Skate Bearing Size: Everything You Need to Know

Skate bearings play a crucial role in the performance and smoothness of your skateboard. Choosing the right bearing size is essential to ensure optimal speed, durability, and precision. This comprehensive guide will delve into the intricacies of skate bearing size, providing all the information you need to make informed decisions.

Understanding Skate Bearing Sizes

Skate bearings come in various sizes, with the most common ones being 608 and 698. These numbers represent the bearing's inner diameter, outer diameter, and width, measured in millimeters.

• 608 bearings: These are the standard size bearings used in most skateboards. They have an inner diameter of 8mm, an outer diameter of 22mm, and a width of 7mm.
• 698 bearings: These bearings are slightly larger than 608 bearings, with an inner diameter of 9mm, an outer diameter of 24mm, and a width of 8mm. They are often used in longboards and cruiser boards.

608 vs. 698 Bearings: Which is Right for You?

The choice between 608 and 698 bearings depends primarily on the type of skateboard you use.

• For standard skateboards: 608 bearings are the ideal choice, as they provide a balance of speed, durability, and precision.
• For longboards and cruiser boards: 698 bearings are better suited, as they offer increased stability and durability due to their larger size.

Types of Skate Bearings

In addition to size, skate bearings are also classified based on their materials and construction.

• Steel bearings: These bearings are made of hardened steel and are the most common type used in skateboards. They offer a good balance of durability and affordability.
• Ceramic bearings: Ceramic bearings are made of silicon nitride ceramic, which is harder and more corrosion-resistant than steel. They provide improved speed and precision but are more expensive than steel bearings.

ABEC Ratings

ABEC (Annular Bearing Engineers Committee) ratings are used to denote the precision and tolerances of skate bearings. Higher ABEC ratings indicate higher precision and reduced friction.

• ABEC 1-3 bearings: These are basic bearings suitable for recreational use and beginners.
• ABEC 5-7 bearings: These bearings offer good balance between precision and durability for general skateboarding.
• ABEC 9 bearings: These bearings provide the highest precision and are recommended for professional skaters or those looking for maximum speed.

Why Skate Bearing Size Matters

Choosing the right bearing size can significantly impact your skateboarding experience.

• Speed: Larger bearings (698) rotate with less resistance, resulting in increased speed.
• Durability: Larger bearings are more robust and can withstand higher loads, increasing their lifespan.
• Precision: Smaller bearings (608) offer greater precision, providing improved control and responsiveness.

Benefits of Choosing the Right Skate Bearing Size

• Enhanced performance: The proper bearing size can optimize your skateboard's speed, handling, and stability.
• Increased durability: Choosing bearings that are suited to your skateboard's weight and riding style can extend their lifespan.
• Improved safety: Bearings that are too small or improperly fitted can compromise your safety while skateboarding.

Pros and Cons of Different Skate Bearing Sizes

Tips and Tricks for Choosing Skate Bearings

• Consider the type of skateboarding you do and the weight you put on your board.
• Choose bearings with an ABEC rating that matches your skill level and riding style.
• Lubricate your bearings regularly to maintain their performance.
• Inspect your bearings periodically for wear or damage and replace them when necessary.
