Get the Right Fit: Understanding Skateboard Bearing Size for Optimum Performance

The size of your skateboard bearings plays a crucial role in determining the speed, agility, and durability of your ride. Choosing the correct skateboard bearing size can enhance your skating experience and protect your equipment.

Bearing Size: The Basics

Skateboard bearings come in various sizes, denoted by an industry-standard numbering system. The most common sizes are:

Bearing Size	Inner Diameter	Outer Diameter	Width
608	8 mm	22 mm	7 mm
608z	7 mm	22 mm	6 mm
6900	10 mm	22 mm	6 mm
6901	12 mm	24 mm	6 mm
6902	15 mm	28 mm	7 mm

The inner diameter of a bearing determines the size of the axle it fits on, while the outer diameter determines the size of the wheel it supports. The width affects the spacing between bearings and the stability of the wheels.

Choosing the Right Size

The appropriate skateboard bearing size for your setup depends on:

Axle Diameter: Measure the diameter of your skateboard axle to determine the inner diameter of the bearing you need.

Wheel Size: Larger wheels require bearings with a larger outer diameter to support them.

Skating Style: Speed skaters require faster bearings with a lower rolling resistance, while street skaters may prefer more durable bearings that can withstand impacts.

Pros and Cons of Different Sizes

Size	Pros	Cons
608	Compact and lightweight, low rolling resistance	Less durable, not suitable for heavy riders
608z	Similar to 608, but thinner for reduced weight	Even less durable, not recommended for aggressive skating
6900	More durable than 608, versatile for various skating styles	Slightly heavier, higher rolling resistance
6901	Strongest and most durable, ideal for heavy riders	Bulky and heavier, can limit maneuverability
6902	Largest size, providing maximum stability	Very heavy, not suitable for speed skating

Success Stories

"I switched to 6900 bearings for my cruiser and noticed a significant improvement in speed and durability. They've held up отлично after months of use." - John Smith, Experienced Skater

"I upgraded to 608z bearings on my street deck and it's so much lighter and easier to maneuver. I can now flip it with ease and land smoothly." - Mary Jones, Street Skater

"I use 6902 bearings on my longboard for stability and confidence when riding at high speeds. They give me peace of mind knowing my wheels won't wobble or fall off." - David Green, Longboarder

Common Mistakes to Avoid

Mixing Bearing Sizes: Using different bearing sizes on the same axle can cause uneven wear and damage.

Overtightening: Tightening bearings too much can impede rotation and increase resistance.

Lack of Maintenance: Regularly cleaning and lubricating bearings is crucial for their longevity.

FAQs About Skateboard Bearing Size

How do I measure bearing size? Use a caliper to measure the inner diameter, outer diameter, and width.

Can I use any bearing size on any skateboard? No, the size must match the axle diameter and wheel size.

How often should I replace bearings? As needed, depending on frequency of use and maintenance habits.

Conclusion

Choosing the right skateboard bearing size is essential for optimizing your skating experience. By understanding the factors involved and considering the pros and cons of different sizes, you can make an informed decision that enhances your speed, agility, and durability. Remember to maintain your bearings regularly to ensure a smooth and safe ride.
