So, you’re looking to squeeze every last bit of performance out of your 608ZZ skateboard bearings. You’re not alone. Whether you’re a seasoned skater chasing faster speeds or a beginner wanting a smoother ride, understanding how to optimize these tiny components is crucial. This article unpacks five practical methods to improve your 608ZZ skateboard bearing performance, focusing on real-world techniques that you can implement today. We’ll cover cleaning, lubrication, maintenance, bearing shields, and even alternative bearing types.
The 608ZZ bearing is the industry standard for skateboards. Its dimensions (8mm inner diameter, 22mm outer diameter, and 7mm width) make it compatible with virtually all skateboards and inline skates. Understanding how this specific bearing type functions is the first step to improving its performance.
The Anatomy of a 608ZZ Bearing
To understand performance, you need to know the basics. The 608ZZ bearing consists of several parts:
- Inner and Outer Rings: These provide the structure for the bearing.
- Ball Bearings: The actual rolling elements that allow for smooth rotation.
- Retainer/Cage: Keeps the ball bearings evenly spaced.
- Shields (ZZ): The “ZZ” designation indicates that the bearing has metal shields on both sides to protect it from dirt and debris.
Factors Affecting 608ZZ Performance
Several factors influence how well your 608ZZ bearings perform:
- Cleanliness: Dirt and grit are the enemy.
- Lubrication: Proper lubrication reduces friction.
- Bearing Quality: Not all bearings are created equal.
- Skating Style: Aggressive skating can wear bearings down faster.
The most impactful thing you can do for your 608ZZ bearings is a thorough cleaning. Over time, dirt, sand, and grime will build up inside, creating friction and slowing you down. A good cleaning can restore a significant amount of performance.
Step-by-Step Cleaning Process
- Remove the Bearings: Carefully remove the bearings from your wheels using a bearing press or a skate tool.
- Remove the Shields: Use a thin, pointed object (like a needle or the tip of a safety pin) to gently pry off the metal shields on both sides. Be careful not to bend them.
- Soak the Bearings: Place the bearings in a container with a solvent like citrus cleaner, mineral spirits, or acetone. Let them soak for at least 10-15 minutes. I personally prefer citrus cleaner due to its lower toxicity and pleasant smell, even though it might require a longer soaking time.
- Agitate and Scrub: Swirl the bearings in the solvent to loosen debris. For stubborn grime, use a small brush (like an old toothbrush) to scrub the bearings.
- Rinse Thoroughly: Remove the bearings from the solvent and rinse them thoroughly with clean water. Make sure all traces of the solvent are gone.
- Dry Completely: This is crucial. Use compressed air or let the bearings air dry completely. Any remaining water can cause rust.
- Relubricate: Apply a high-quality skateboard bearing lubricant (more on this later).
- Reinstall Shields: Carefully press the shields back into place.
- Reinstall Bearings: Put the bearings back into your wheels.
Why This Matters
Cleaning removes the friction-causing debris that accumulates inside the bearing. A clean bearing rolls much faster and smoother.
Once your bearings are clean, proper lubrication is essential. Lubrication reduces friction, protects against wear, and helps dissipate heat.
Choosing the Right Lubricant
There are two main types of lubricants for skateboard bearings:
- Oil-Based Lubricants: These are thinner and provide less resistance, resulting in faster speeds. They require more frequent application.
- Grease-Based Lubricants: These are thicker and offer more protection against dirt and water. They last longer but may slightly reduce speed.
I’ve experimented with both and found that for street skating, a light oil-based lubricant offers the best balance of speed and protection, assuming you’re diligent about cleaning and re-lubricating regularly. For more rugged terrain or wet conditions, a grease-based lubricant is a better choice.
Applying Lubricant Correctly
- Apply Sparingly: A few drops are all you need. Over-lubricating can attract more dirt.
- Distribute Evenly: Rotate the bearing after applying the lubricant to ensure it’s evenly distributed.
- Reinstall Shields: This helps keep the lubricant inside the bearing and protects it from contamination.
The Downside of Neglecting Lubrication
Running bearings without lubrication can cause them to overheat and wear out quickly. You’ll notice a decrease in speed and a rough, noisy ride.
The “ZZ” in 608ZZ indicates metal shields on both sides. These shields are designed to protect the bearings from dirt and debris, but they also create a small amount of friction.
Removing Shields for Speed
Some skaters choose to remove the shields on one or both sides of their bearings to reduce friction and increase speed. This is a trade-off.
The Shield Dilemma
- Pros of Removing Shields: Increased speed, slightly smoother roll.
- Cons of Removing Shields: Increased risk of contamination, shorter bearing lifespan.
In my experience, removing shields is only worthwhile if you’re skating on a very clean surface and are meticulous about cleaning and lubricating your bearings frequently. Otherwise, the added protection is worth the slight reduction in speed.
Alternative Shield Materials
While most 608ZZ bearings come with metal shields, some manufacturers offer bearings with rubber shields. Rubber shields provide a better seal against dirt and water while still offering relatively low friction.
Proper maintenance is key to extending the life of your 608ZZ skateboard bearings and maintaining their performance.
Regular Cleaning and Lubrication
As discussed earlier, regular cleaning and lubrication are crucial. The frequency depends on your skating conditions and style.
Visual Inspections
Regularly inspect your bearings for signs of wear or damage. Look for:
- Rust: Indicates moisture exposure.
- Cracks: A sign of stress or impact damage.
- Roughness: Suggests dirt or damage to the ball bearings.
Proper Installation
Ensure that your bearings are properly installed in your wheels. Over-tightening or uneven pressure can damage them.
Storage
When not in use, store your skateboard in a dry place to prevent rust.
While the 608ZZ is the standard, there are alternative bearing types that can offer improved performance in certain situations.
Ceramic Bearings
Ceramic bearings use ceramic balls instead of steel. Ceramic bearings are lighter, harder, and smoother than steel bearings. This translates to faster speeds and longer lifespan.
- Pros: Higher speeds, less friction, longer lifespan, corrosion resistant.
- Cons: More expensive.
Hybrid Ceramic Bearings
These bearings use steel rings with ceramic balls. They offer a compromise between the performance of full ceramic bearings and the affordability of steel bearings.
Precision Ratings (ABEC)
The ABEC rating (Annular Bearing Engineering Committee) is a system for rating the tolerances of bearings. Higher ABEC ratings (e.g., ABEC 7, ABEC 9) indicate tighter tolerances and potentially smoother performance.
- However, the ABEC rating is not the only factor that determines bearing performance. The quality of the materials and the manufacturing process are also important.
Table of Bearing Types and Performance
| Bearing Type | Material | Pros | Cons | Best For |
|---|---|---|---|---|
| 608ZZ (Standard) | Steel | Affordable, widely available, durable. | Can be slow if not maintained, susceptible to rust. | General skating |
| Hybrid Ceramic | Steel Rings/Ceramic Balls | Faster than steel, more durable than steel, less expensive than ceramic. | Still susceptible to rust on steel components. | Speed and durability balance |
| Full Ceramic | Ceramic | Fastest, most durable, corrosion-resistant. | Most expensive, potentially brittle under extreme impact. | Professional skating, high speeds |
Improving 608ZZ skateboard bearing performance is a combination of cleaning, lubrication, maintenance, and smart choices. By following these five methods, you can unlock the full potential of your bearings and enjoy a smoother, faster, and more enjoyable skating experience. Don’t underestimate the power of a clean, well-lubricated bearing! Remember, regular maintenance is key to extending the lifespan of your bearings and maintaining their peak performance.
