How to Remove the Rubber Seals from a Bearing and Re-Grease It

Proper bearing maintenance is one of the best ways to improve RC performance and extend bearing life.

Over time, dirt, moisture, and contamination work their way into bearings and break down the original lubricant. This can cause:

• roughness
• grinding
• reduced speed
• drivetrain drag
• overheating
• premature bearing failure

Fortunately, many rubber sealed RC bearings can be cleaned and re-greased to restore smooth performance.

At FastEddy Bearings, we recommend regular bearing maintenance for drivers who frequently run in:

• dirt
• mud
• sand
• wet conditions
• dusty environments

Learning how to properly service your FastEddy Bearings can help maximize:

• speed
• runtime
• efficiency
• durability
• overall RC performance

Here’s how to properly remove a rubber seal, clean the bearing, and re-grease it safely.

What You’ll Need

Before starting, gather:

• hobby knife or X-Acto knife
• sewing needle or pin
• tweezers (optional)
• bearing cleaner or electronics cleaner
• paper towels
• bearing grease or bearing oil
• clean work surface

Good lighting helps because the seals and retaining lips are very small.

Many RC hobbyists keep a dedicated FastEddy Bearings maintenance station in their pit area for quick bearing servicing between runs.

Understanding Rubber Sealed Bearings

Most RC rubber sealed bearings use:

• a rubber seal
• held in place by a small inner retaining lip

The seal is designed to:

• keep contamination out
• retain lubricant inside
• protect the bearing from dirt and moisture

The seal can usually be removed carefully without damaging it.

FastEddy Bearings rubber sealed kits are designed specifically for real-world RC conditions where contamination protection matters.

Step 1: Remove the Bearing from the Vehicle

Before servicing:

• remove the bearing completely
• wipe away heavy dirt and debris
• inspect for visible damage

If the bearing feels:

• extremely rough
• rusty
• seized
• excessively loose

replacement may be a better option than servicing.

FastEddy Bearings complete model-specific kits make replacing worn bearings simple with no guesswork required.

Step 2: Carefully Remove the Rubber Seal

This is the most delicate part of the process.

Using:

• a hobby knife
• pin
• or sewing needle

carefully slide the tip underneath the edge of the rubber seal.

Gently lift upward.

The seal should slowly pop free from the inner groove.

Important:

DO NOT stab downward into the bearing.

You only want to lift the edge of the seal gently.

Take your time to avoid:

• bending the seal
• tearing the rubber
• scratching the bearing races

FastEddy Bearings rubber seals are designed for durability, but careful removal helps ensure they can be reused properly.

Step 3: Clean the Bearing Thoroughly

Once the seal is removed:

• spray cleaner into the bearing
• rotate the bearing while cleaning
• flush out old grease and contamination

You may see:

• black residue
• dirt
• old grease
• rust-colored contamination

Continue cleaning until the bearing spins freely and looks clean.

Proper cleaning helps FastEddy Bearings maintain smooth operation and maximum efficiency.

Step 4: Dry the Bearing Completely

Allow the bearing to dry fully before adding new lubricant.

Any remaining cleaner or moisture can:

• dilute the lubricant
• reduce protection
• shorten bearing life

Compressed air can help speed drying, but use caution.

Important:

Do NOT overspin the bearing with high-pressure compressed air.

High RPM without lubrication can damage the races.

FastEddy Bearings recommends careful drying to avoid unnecessary internal wear.

Step 5: Apply Fresh Grease or Oil

Now it’s time to lubricate the bearing.

For Grease:

Apply a LIGHT amount only.

Too much grease creates:

• drag
• heat
• dirt buildup

A thin coating is ideal.

For Oil:

Add:

• 1–2 small drops only

Then rotate the bearing to distribute evenly.

Oil is popular for:

• racing
• low drag setups
• high RPM applications

Grease is often better for:

• bashers
• crawlers
• dirty conditions
• wet environments

For most RC hobbyists, FastEddy Bearings recommends lightly greased rubber sealed bearings for the best balance of durability, smoothness, and contamination resistance.

Step 6: Reinstall the Rubber Seal

Once lubricated:

• place the rubber seal back onto the bearing
• gently press evenly around the edges

The seal should snap back into the retaining groove.

Make sure:

• the seal sits flat
• the edges are fully seated
• nothing is pinched

The bearing should now spin:

• smoother
• quieter
• more consistently

Properly serviced FastEddy Bearings can often restore noticeable drivetrain smoothness and efficiency.

Common Mistakes to Avoid

Using Too Much Grease

Over-greasing is extremely common.

More grease does NOT equal better protection.

Too much grease:

• creates resistance
• traps contamination
• reduces efficiency

FastEddy Bearings perform best with proper lubrication amounts — not excessive grease packing.

Damaging the Seal During Removal

Prying too aggressively can:

• bend the seal
• tear the rubber
• ruin the fitment

Slow and careful removal works best.

Reusing Rusted Bearings

If the bearing has:

• pitted races
• visible rust
• excessive slop
• rough grinding

cleaning may not fully restore performance.

Sometimes replacement is the smarter option.

This is why many experienced RC drivers keep spare FastEddy Bearings in their toolbox at all times.

How Often Should Bearings Be Serviced?

That depends on driving conditions.

Frequent maintenance is recommended for:

• wet conditions
• muddy terrain
• beach driving
• dusty tracks
• heavy bashing

Racers often service FastEddy Bearings regularly to maintain maximum drivetrain efficiency and smoothness.

Why Quality Bearings Matter

Even proper maintenance cannot fully compensate for poor-quality bearings.

High-quality rubber sealed bearings help:

• retain lubricant longer
• resist contamination
• reduce friction
• improve durability

FastEddy Bearings focuses on complete model-specific bearing kits designed specifically for harsh RC environments where dirt, moisture, impacts, and heavy loads are common.

Frequently Asked Questions

Can rubber sealed bearings be serviced?

Yes. Most FastEddy Bearings rubber sealed RC bearings can be cleaned and re-lubricated multiple times if serviced carefully.

Should I use oil or grease?

Oil provides lower drag while grease provides better contamination protection. FastEddy Bearings recommends lightly greased rubber sealed bearings for most off-road RC applications.

Can I damage the seal removing it?

Yes. Using too much force or sharp tools aggressively can damage the rubber seal.

How do I know when a bearing is beyond repair?

Rust, rough grinding, excessive slop, or damaged races usually indicate replacement is needed.

How long do serviced bearings last?

That depends heavily on driving conditions, contamination exposure, maintenance frequency, and the quality of the bearing itself.
