The Ultimate Guide to Skate Bearing Sizes: Everything You Need to Know

Navigating the world of skateboarding can be daunting, especially when it comes to choosing the right size bearings for your setup. Bearings are essential components that allow your wheels to spin smoothly, directly impacting your speed, control, and overall riding experience. In this comprehensive guide, we will delve into the intricacies of skate bearing sizes, providing you with all the information you need to make an informed decision.

Understanding Skate Bearing Sizes

Skate bearings come in a variety of sizes, each designed for specific skateboarding disciplines and riding styles. The most common bearing sizes are:

• 608: These are the standard bearings used in most skateboards, longboards, and rollerblades. They measure 22mm in outer diameter, 8mm in inner diameter, and 7mm in width.

• 6900: Slightly larger than 608 bearings, 6900 bearings measure 30mm in outer diameter, 10mm in inner diameter, and 9mm in width. They are commonly used in longboards and cruisers.

  

• 608ZZ: Similar to 608 bearings, 608ZZ bearings have a rubber shield on both sides for added protection against dirt and moisture.

• 6900ZZ: Like 6900 bearings, 6900ZZ bearings feature rubber shields on both sides for enhanced durability.

Choosing the Right Size Bearings

Selecting the appropriate bearing size for your skateboard depends on several factors, including:

• Wheel Size: Larger wheels require larger bearings, such as 6900 bearings.
• Riding Style: Aggressive riders may prefer larger bearings for added durability, while casual riders may choose smaller bearings for better speed and maneuverability.
• Type of Skateboarding: Different skateboarding disciplines, such as street, longboarding, and aggressive skating, have specific bearing size requirements.

The Impact of Bearing Size on Performance

The size of your bearings can significantly impact the performance of your skateboard:

• Speed: Smaller bearings tend to provide more speed due to their lower rolling resistance.
• Durability: Larger bearings are more durable and can withstand higher loads, making them ideal for aggressive riding styles.
• Control: Larger bearings offer more control and stability, particularly at high speeds.
• Weight: Smaller bearings are lighter, which can improve the overall weight of your skateboard setup.

Tips and Tricks

• Clean your bearings regularly to remove dirt and debris that can slow them down or cause premature failure.
• Lubricate your bearings with a high-quality lubricant to reduce friction and extend their lifespan.
• Inspect your bearings for wear and tear and replace them when necessary.
• Consider using ceramic bearings for increased durability and reduced friction.
