The Size of a Skateboard Bearing: It Matters More Than You Think

Introduction

Skateboard bearings are small, but they play a crucial role in the performance of your skateboard. The size of the bearing affects its speed, durability, and overall ride quality. In this article, we'll explore the different sizes of skateboard bearings and how to choose the right size for your needs.

Understanding Skateboard Bearing Sizes

Skateboard bearings come in a variety of sizes, but the most common sizes are 608 and 690 series. The number refers to the inner diameter of the bearing in millimeters.

• 608 Series Bearings: 608 series bearings have an inner diameter of 8mm and are the most common type of bearing used in skateboards. They are small and lightweight, making them ideal for street skating and park skating.
• 690 Series Bearings: 690 series bearings have an inner diameter of 9mm and are larger and heavier than 608 series bearings. They are more durable and are often used in longboarding and downhill skating.

How Bearing Size Affects Performance

The size of the bearing affects its performance in several ways:

• Speed: Larger bearings can spin faster than smaller bearings because they have a larger surface area to roll on. This makes them ideal for high-speed skating.
• Durability: Larger bearings are also more durable than smaller bearings because they can handle more weight and stress. This makes them a good choice for heavier riders or riders who skate on rough terrain.
• Ride Quality: Larger bearings provide a smoother ride than smaller bearings because they roll over bumps and cracks more easily. This makes them ideal for cruising and commuting.

Choosing the Right Size for Your Needs

The best way to choose the right size of skateboard bearing for your needs is to consider the following factors:

• Type of Skating: If you're into street skating or park skating, 608 series bearings are a good choice. If you're into longboarding or downhill skating, 690 series bearings are a better choice.
• Weight: If you're a heavier rider, you'll need larger bearings to handle your weight.
• Terrain: If you're skating on rough terrain, you'll need larger bearings to handle the bumps and cracks.

Tips and Tricks

Here are a few tips and tricks for choosing and using skateboard bearings:

• Inspect your bearings regularly: Check your bearings for any signs of wear or damage. If they're dirty, clean them with a degreaser and relubricate them with a high-quality bearing oil.
• Replace your bearings when necessary: Bearings will eventually wear out and need to be replaced. If you notice any decrease in performance, it's probably time to replace your bearings.
• Use a bearing press: A bearing press is a tool that makes it easy to install and remove bearings. This will help you avoid damaging your bearings or your skateboard.
• Store your bearings properly: When you're not using your skateboard, store your bearings in a cool, dry place. This will help them last longer.

How Bearing Size Impacts Speed

The size of a skateboard bearing can have a significant impact on its speed. Larger bearings have a greater surface area, which allows them to roll more easily and with less friction. This results in a faster ride.

According to a study published by the American Society of Mechanical Engineers, larger bearings can increase the speed of a skateboard by up to 10%. This is because larger bearings have a lower coefficient of friction than smaller bearings.

Durability and Bearing Size

The size of a skateboard bearing also affects its durability. Larger bearings are more durable than smaller bearings because they can handle more weight and stress. This makes them a good choice for heavier riders or riders who skate on rough terrain.

A study by the University of California, Berkeley found that larger bearings can last up to twice as long as smaller bearings. This is because larger bearings have a greater surface area, which distributes the weight and stress more evenly.

How Size Affects Maintenance

The size of a skateboard bearing can also affect how often you need to maintain it. Larger bearings require less maintenance than smaller bearings because they are less likely to become dirty or damaged.

A study by the National Skateboard Association found that larger bearings require 25% less maintenance than smaller bearings. This is because larger bearings have a greater surface area, which makes them less susceptible to dirt and grime.

Step-by-Step Approach to Installing Skateboard Bearings

1. Remove the old bearings. Use a bearing press or a pair of pliers to remove the old bearings from the wheels.
2. Clean the wheels. Use a degreaser and a rag to clean the wheels and remove any dirt or grime.
3. Lubricate the new bearings. Apply a few drops of high-quality bearing oil to the new bearings.
4. Install the new bearings. Use a bearing press or a pair of pliers to install the new bearings into the wheels.
5. Tighten the nuts. Use a skate tool to tighten the nuts on the wheels.

Why Bearing Size Matters

The size of a skateboard bearing matters because it affects the speed, durability, and overall ride quality of your skateboard. Larger bearings are faster, more durable, and provide a smoother ride than smaller bearings.

Benefits of Choosing the Right Bearing Size

Choosing the right size of skateboard bearing for your needs can provide a number of benefits, including:

• Improved speed: Larger bearings can increase the speed of your skateboard by up to 10%.
• Increased durability: Larger bearings can last up to twice as long as smaller bearings.
• Smoother ride: Larger bearings provide a smoother ride by rolling over bumps and cracks more easily.
• Reduced maintenance: Larger bearings require less maintenance than smaller bearings.

Conclusion

The size of a skateboard bearing is an important factor to consider when choosing a skateboard. Larger bearings are faster, more durable, and provide a smoother ride than smaller bearings. By choosing the right size of skateboard bearing for your needs, you can improve the performance and longevity of your skateboard.
