Grease Skateboard Bearings: Best Tips

Grease skateboard bearings is crucial for maintaining smooth performance and prolonging the life of the bearings.

Proper bearing lubrication reduces friction, allowing the wheels to spin more freely and quietly.

This blog will provide skateboarders with practical advice and essential tips on properly greasing their bearings.

Understanding Skateboard Bearings

Components of a Skateboard Bearing

• Outer Race: The outer race, is the part that fits securely into the wheel, keeping the bearing components aligned and stable.
• Inner Race: The inner ring that fits onto the skateboard axle and allows the bearing to spin.
• Cage (Retainer): The cage is a small part within the bearing that holds the balls in place and keeps them evenly spaced.
• Balls: The small round elements that roll between the inner and outer races, allowing the bearing to spin smoothly.
• Shields: Protective covers that keep dirt and water out and hold the lubricant inside.

Do you know what are the standard skateboard bearings dimensions.

Why Grease is Crucial for Bearings

• Reducing Friction: It creates a smooth layer between parts, allowing the bearing to spin more easily and smoothly.
• Preventing Corrosion: Grease keeps water, dirt, and moisture out, protecting the bearings from rust and damage.
• Improving Lifespan: By reducing friction and preventing rust, grease helps the bearings last longer and perform better.

Tools and Materials Needed for Greasing Bearings

Essential Tools

• Skate specific Tool: Used to remove the wheels from the skateboard and sometimes to remove the bearings from the wheels.
• Bearing Puller: A tool specifically designed to remove bearings from the wheels without damaging them.
• Solvent: Used to clean the bearings by removing residual grease, collected residue, and any debris. Rubbing alcohol or a bearing cleaner is commonly used.
• Grease: Lubricant used to reduce friction and protect the bearings from wear and corrosion.
• Pin or Razor Blade: Used to remove the shields from the bearings, making it easier to apply grease and clean the bearing.
• Container: A small container for soaking the bearings in solvent or to hold the bearings while applying grease.

Choosing the Right Grease

Step-by-Step Guide to Greasing Skateboard Bearings

Step 1 - Disassemble the Bearings

To remove skateboard wheels and bearings, use a skate tool or wrench to unscrew each axle nut counterclockwise, then set the nuts aside.

Carefully slide the wheels off, keeping any washers safe.

To pop out the bearings, place the wheel's edge on the axle and tilt it to pry each bearing out.

Step 2 - Remove Bearing Shields

To carefully remove the bearing shields without causing damage, take a thin razor blade or pin.

Carefully insert it beneath the shield's edge and slowly pry it up to remove.

Work slowly around the shield’s perimeter, lifting it slightly as you go.

Avoid prying too forcefully; instead, ease the shield out by gradually applying pressure around the entire edge.

This technique minimizes bending or warping, ensuring the shield remains intact for reinstallation.

Step 3 - Clean the Bearings

To clean your bearings, place them in a container.

Fill the container with isopropyl alcohol or acetone until the bearings are fully submerged.

Allow the bearings to soak in the solution for several minutes to loosen dirt and debris.

Then, gently swirl the container to help loosen the dirt and grime.

If needed, use a soft brush to remove stubborn debris. Take them out and let them air-dry completely before adding lubricant and reinstalling.

Step 4 - Dry the Bearings

To dry your bearings, take them out of the solvent and pat them with a clean rag.

Use compressed air to blow out any remaining moisture, being careful not to spin the bearings too fast.

Finally, let them air-dry completely before adding lubricant.

Step 5 - Apply Grease to the Bearings

To apply grease to each bearing, use a small amount—about the size of a pea or less for each one. 

Apply it sparingly to avoid excess buildup, which can attract dirt and slow down the bearing.

Spread the grease evenly around the balls inside the bearing using a clean, small tool (like a toothpick or pin).

Rotate the bearing gently to work the grease into all areas, ensuring smooth movement without adding too much.

This way, the bearing stays well-lubricated without any sticky buildup.

Step 6 - Reassemble the Bearings

To replace the shields, carefully align each shield over the open side of the bearing and gently press it back into place until it snaps securely.

Once the shields are on, position the bearing over the wheel's bearing seat and press it in.

For a snug fit, press the bearing into the wheel firmly with your hand.

Alternatively, place the bearing on the truck axle, then press the wheel onto it and push down until the bearing is fully seated.

Repeat the process on the other side of the wheel, then securely reattach the wheels to your skateboard.

Step 7 - Test the Bearings

After greasing the bearings and reassembling the wheels, spin each wheel by hand to spread the grease evenly.

Keep spinning until the wheels move smoothly without any resistance or wobbling.

This ensures the bearings are properly lubricated and run well.

Common Mistakes to Avoid When Greasing Bearings

Over-Greasing the Bearings

Too much grease can create extra friction inside the bearing, leading to increased resistance as the parts try to move.

This excess buildup can slow down the bearings, making them less efficient. It also attracts dirt and debris, which can further slow the bearings and cause them to wear out faster.

Applying the right amount of grease ensures that the bearings move smoothly. It also prevents buildup, keeping the bearings running efficiently.

Using the Wrong Type of Grease

WD-40 and motor oil are not ideal for skateboard bearings because they do not provide proper lubrication.

Additionally, they tend to attract dirt, which can damage the bearings and reduce their performance.

WD-40 is more of a cleaner, not a lubricant, and motor oil is too thick, which can cause friction and wear.

Using a proper bearing lubricant designed specifically for skateboard bearings helps ensure smooth movement and long-lasting performance.

Skipping the Cleaning Process

Cleaning bearings before greasing is essential to remove dirt, dust, and old lubricant.

If left inside, these contaminants can mix with the new grease, increasing friction and reducing the bearing's performance.

Contaminants can also cause the bearings to wear out faster and affect their smooth movement.

By thoroughly cleaning the skateboard bearings first, you remove any debris that could interfere with their performance.

This ensures that the grease can work effectively, allowing the bearings to function smoothly and at their best.

How Often Should You Grease Skateboard Bearings?

Factors That Affect Greasing Frequency

• Riding Environment: If you skate in wet, dusty, or muddy conditions, you’ll need to clean and grease your skateboard bearings more frequently. This helps prevent rust and dirt buildup, ensuring the bearings stay in good condition and perform smoothly.
• Skating Frequency: The more frequently you skate, the sooner you'll need to grease your skateboard bearings to ensure they continue to run smoothly.
• Bearing Type: Higher-quality bearings need less frequent greasing, while lower-quality ones may need more care.
