How to Install RC Car Ball Bearings: Complete Step-by-Step Guide
Upgrading your ball bearings is one of the most impactful maintenance tasks you can perform. Follow these steps to ensure proper installation and maximum benefit from your new bearings.
What You’ll Need
- Hex driver set (matched to your chassis screws)
- New ball bearings (matched to your model)
- Bearing puller tool (optional but helpful)
- Shop towels or cleaning cloth
- Light machine oil or bearing lubricant
- Work surface (clear workspace recommended)
- Parts organiser or small container for screws
Installation Steps
- Identify bearing locations: Consult your RC car’s manual to locate all bearing positions. Most vehicles have bearings in the wheel hubs, suspension arms, and steering components. Mark down the bearing size (e.g., 5x11x4mm) for each location.
- Disassemble the chassis: Using your hex driver set, carefully remove the screws holding suspension arms and wheel assemblies. Keep all screws organised in a parts container to avoid losing them.
- Remove old bearings: Gently pry out old bearings using a small screwdriver or bearing puller tool. If bearings are stuck, apply slight pressure whilst rotating the assembly. Be careful not to damage the bearing races (the metal seats the bearings sit in).
- Inspect bearing seats: Before installing new bearings, examine the bearing races for damage. Dirt or corrosion here will reduce performance. Clean with a dry cloth if needed.
- Press in new bearings: Carefully push new bearings into their seats. Apply even pressure—never hammer bearings in, as this can damage them. The bearing should slide in with moderate resistance and sit flush with the seat.
- Lubricate appropriately: Add a tiny amount of bearing lubricant to the bearing surface. Use very sparingly—excess oil attracts dirt and reduces performance. A single drop per bearing is typically sufficient.
- Reassemble the chassis: Reinstall all suspension arms and wheel assemblies, tightening screws firmly but not over-tightening (which can create unnecessary friction).
- Test operation: Spin the wheels by hand to ensure smooth, free rotation. The wheels should spin freely without grinding or resistance. If friction is present, remove the wheels and check bearing installation.
- Drive test: Take your RC car for a test drive on a flat surface. You should immediately notice smoother acceleration and better handling. Listen for any grinding sounds that might indicate installation problems.
Common Mistakes to Avoid When Upgrading Ball Bearings
Even small errors during bearing selection or installation can undermine the benefits of your upgrade. Learn from others’ mistakes:
- Buying the wrong bearing size for your model: Different chassis use different bearing sizes (5x11mm, 5x13mm, 6x13mm, etc.). Installing oversized or undersized bearings creates poor fitment and poor performance. Always verify your model’s bearing specifications before ordering. Check your vehicle’s manual or the manufacturer’s website to confirm exact sizes.
- Over-lubrication: Excessive oil attracts dirt and creates drag, negating the benefits of new bearings. Apply lubricant sparingly—typically just one small drop per bearing. If your car feels slower after installation, over-lubrication is often the culprit. Clean bearings with a solvent and reapply minimal lubricant.
- Mixing different bearing quality levels: Installing premium ceramic bearings in some positions and budget bearings in others creates inconsistent performance. Replace bearings throughout your chassis with the same quality tier for optimal results.
- Forcing bearings into worn bearing races: If the original bearing seats are damaged or enlarged, new bearings won’t sit properly. Inspect bearing races carefully before installation. If damaged, you may need to replace suspension arms or other affected components.
- Ignoring sealed vs. unsealed options: Sealed bearings provide dirt protection but increase friction. Unsealed bearings offer maximum speed but require more frequent cleaning. Choose the type that matches your driving environment and maintenance commitment.
- Tightening suspension screws too much: Over-tightening creates unnecessary bearing pressure and friction. Use firm but not excessive force when reassembling. The suspension should move smoothly without play.
- Not cleaning old bearing residue: Old grease and dirt left in bearing seats will contaminate new bearings. Always clean bearing seats thoroughly before installation. Use a dry cloth and wipe away all debris.
Performance Impact: What to Expect from Bearing Upgrades
Quality ball bearings deliver measurable improvements across several performance metrics:
- Acceleration: Expect 5–15% improvement in acceleration on straightaways as friction decreases
- Top Speed: Premium ceramic hybrids can add 2–5 mph to top speed on flat terrain
- Handling Response: Steering feels more responsive and precise with reduced friction
- Battery Efficiency: Motors work less hard against bearing friction, extending run times by 10–20%
- Longevity: Quality bearings last 2–3 times longer than budget alternatives
The most noticeable improvement occurs when upgrading from worn stock bearings to quality aftermarket options. Each subsequent upgrade (mid-range to premium, or standard to ceramic hybrid) delivers smaller but still meaningful gains.
Bearing Maintenance Tips for Extended Lifespan
Proper maintenance maximises bearing lifespan and performance:
- Clean after wet conditions: After muddy or wet driving, remove mud from bearing areas and allow to dry completely before storage
- Occasional re-lubrication: Every 5–10 hours of driving, add a tiny drop of fresh lubricant to bearing surfaces
- Inspect for damage: Periodically check bearings for visible damage, corrosion, or debris
- Replace proactively: Don’t wait for bearing failure. Replace them when they show resistance or grinding, even if still functional
- Store properly: Keep unused bearings in a dry environment away from moisture and extreme temperatures
Bearing Sizes: Understanding RC Car Specifications
Ball bearing sizes are standardised using this format: bore diameter × outer diameter × width, measured in millimetres.
Common RC car bearing sizes include:
- 5×11×4mm (5×11): Most popular size, found in wheel hubs, arms, and many other locations across numerous RC platforms
- 5×13×4mm (5×13): Used in certain suspension arms and speciality applications
- 6×13×5mm (6×13): Found in larger-scale vehicles and some competition models
- 8×12×3.5mm (8×12): Used in specific Traxxas and other brand models
- 2×5×2.5mm (2×5): Tiny bearings used in steering components and lightweight models
Always verify your specific model’s bearing requirements before purchasing. Installing the wrong size creates poor fitment and performance issues.
Brand Compatibility: Cross-Platform Bearing Interchange
Whilst brand-specific bearings offer perfect fitment, quality aftermarket options work across multiple platforms:
- Tamiya, Traxxas, HPI, and Team Losi all use standard 5×11mm bearings in similar positions
- Check your model’s manual or the manufacturer’s website to confirm compatible sizes
- When in doubt, contact the manufacturer’s customer service with your model number
- Online RC forums often have compatibility charts for cross-brand bearing use
Mixing brands within a single vehicle is perfectly acceptable, as long as bearing sizes match and quality is consistent throughout.
What You’ll Notice Immediately After Installation
When you first upgrade to quality ball bearings, several noticeable changes occur within the first few minutes of driving. Your RC car will feel noticeably smoother through acceleration, with less resistance from the drivetrain. The steering response improves significantly—inputs feel more direct and precise, especially through tight corners. You may hear a subtle difference too; quality bearings produce a quieter, more refined tone compared to worn bearings that might produce grinding or squeaking sounds.
Beyond the immediate sensory improvements, you’ll observe extended battery run times. Because the motor works against less friction, it draws lower amperage and runs cooler, allowing your battery to deliver power for longer. Over several driving sessions, you’ll also notice more consistent performance—whilst worn bearings create variable drag that changes as debris accumulates, quality bearings maintain uniform performance. These changes compound over time, making bearing upgrades one of the highest-return modifications available to RC enthusiasts.

Frequently Asked Questions About RC Car Ball Bearings
What size ball bearings do I need for my RC car?
The most common size is 5×11×4mm, used in wheel hubs and suspension arms across Traxxas, Tamiya, Arrma, and other brands. However, specific sizes vary by model and chassis position. Always consult your vehicle’s manual or the manufacturer’s website for exact specifications. When ordering, have your model name and year ready to ensure correct sizing.
Are ceramic hybrid bearings worth the extra cost?
Yes, for serious racers and performance enthusiasts. Ceramic hybrid bearings deliver measurable speed and efficiency gains, lasting 2–3 times longer than steel-only designs. For casual hobby runners, mid-range bearings provide excellent value. For competitive racing or maximum performance chasing, the ceramic hybrid investment pays dividends.
How often should I replace RC car ball bearings?
With proper maintenance, quality bearings last 20–50+ hours of driving. Replace them sooner if you notice grinding sounds, resistance during wheel spinning, or visible damage. After wet or muddy driving, inspect bearings for debris and clean accordingly. Many enthusiasts do a preventive bearing replacement every season or before major races.
Can I use different bearing brands in the same RC car?
Yes, absolutely. Mixing Traxxas, Tamiya, HPI, and other quality brands is fine as long as bearing sizes match and you maintain consistent quality levels. However, for optimal performance, using the same brand throughout your chassis ensures uniform friction and handling characteristics.
What’s the difference between sealed and unsealed ball bearings?
Sealed bearings include protective covers that keep dirt and moisture out, making them ideal for muddy or wet driving. However, seals increase friction and reduce maximum speed. Unsealed bearings offer minimal friction and maximum speed but require more frequent cleaning and maintenance. Choose sealed bearings if durability and all-weather use matter most; choose unsealed for pure speed and competitive racing.
Do ball bearing upgrades really make RC cars faster?
Yes, noticeably so. Quality bearing upgrades reduce friction, allowing motors to work more efficiently. Expect 2–5 mph top speed increases and 5–15% acceleration improvements, especially when upgrading from worn stock bearings. The improvement is most dramatic when going from budget to mid-range or premium tiers.
What tools do I need to install new ball bearings?
You need a hex driver set matching your chassis fasteners, a small screwdriver or bearing puller to remove old bearings, and bearing lubricant. A bearing puller tool (optional) makes removal easier, though careful screwdriver technique works fine. Most RC enthusiasts already own hex drivers, so bearing installation requires minimal additional investment.
Should I lubricate new ball bearings?
Yes, but sparingly. Apply a single tiny drop of light machine oil or bearing-specific lubricant to the bearing surface. Excessive lubrication creates drag and attracts dirt. After initial application, re-lubricate every 5–10 hours of driving or after wet conditions. Less lubrication is better than more—when in doubt, err on the side of minimal application.
Are OEM (Original Equipment Manufacturer) bearings better than aftermarket options?
OEM bearings from Traxxas, Tamiya, or other manufacturers offer proven reliability and perfect fitment but aren’t necessarily superior to quality aftermarket options. Premium aftermarket bearings like FastEddy ceramic hybrids often outperform OEM alternatives in speed and durability. For value and reliability, OEM is excellent; for maximum performance, premium aftermarket is your choice.
Can I install bearings without removing entire suspension arms?
Sometimes, depending on your model’s design. Some vehicles allow bearing access without full disassembly, whilst others require complete suspension removal. Check your manual for specific guidance. Removing suspension arms takes longer but ensures you can thoroughly clean bearing seats and properly inspect for damage. Most enthusiasts recommend full disassembly for quality results.
