Overview

The Traxxas Ball Bearings, Black Rubber Sealed (6x12x4mm) are essential replacement components for maintaining peak performance in your RC car or truck. Whether you're running a Traxxas Stampede 4X4 HD VXL, TRX-4 crawler, or any other compatible Traxxas model, these precision ball bearings deliver the smooth, long-lasting performance that serious RC enthusiasts demand. Black-seal bearings represent a significant step up from standard blue-seal alternatives, offering superior protection and reduced maintenance requirements — particularly valuable if you're bashing your RC car in dirty environments across the UK.

Rubber-sealed ball bearings are fundamental to any high-performance RC setup. They provide the smooth rotation and precise handling that separate a finely-tuned RC vehicle from an average basher. These Traxxas OEM bearings are engineered to exacting standards, ensuring that your RC monster truck, crawler, or stadium truck maintains consistent performance lap after lap. When your bearings wear out or become contaminated with dirt and debris, replacing them with genuine Traxxas components is the most cost-effective way to restore your vehicle's handling and responsiveness without expensive overhauls.

For RC enthusiasts in the UK looking for reliable replacement bearings, these black-seal units offer outstanding value and genuine peace of mind. Sold as a pair, they're ready to install and compatible with numerous Traxxas models across different scales and platforms. Whether you're a weekend basher, a serious racer, or someone discovering the world of ready-to-run RC for the first time, maintaining your bearings is crucial for long-term vehicle reliability and performance.

Key Features

• Black Rubber Seal Design — These bearings feature an advanced black rubber seal that provides an even tighter seal compared to standard blue-seal bearings, offering ultimate protection against dirt, moisture, and contamination. This enhanced sealing is especially important if you regularly run your RC car in muddy, dusty, or wet conditions typical of UK outdoor environments, as it dramatically reduces the need for frequent maintenance and bearing replacement.
• Precision Ball Bearing Construction — Manufactured to exacting Traxxas standards, these ball bearings deliver smooth, consistent rotation and precise handling characteristics. The precision engineering ensures minimal friction and wear, translating directly into better steering response, smoother acceleration, and more predictable cornering behaviour in your RC vehicle.
• Reduced Maintenance Requirements — The superior sealing properties of black-seal bearings mean you'll spend less time cleaning and servicing your RC car. This is a real practical benefit for busy enthusiasts who want to maximise track time and minimise maintenance time, making these bearings excellent value for long-term ownership.
• Sold as a Pair — Each package contains two bearings, allowing you to service multiple bearing locations on your vehicle or maintain a spare set for quick field replacement during competitions or track days without waiting for additional orders.
• Genuine Traxxas OEM Component — As factory-original equipment manufactured by Traxxas, these bearings guarantee perfect fitment and compatibility with your Traxxas RC model. Using genuine components ensures you maintain your vehicle's warranty and performance specifications.
• Universal Compatibility Across Traxxas Range — These 6x12x4mm bearings are compatible with numerous Traxxas models including the Stampede 4X4 HD VXL brushless electric monster truck, multiple TRX-4 crawler variants, and other platforms, making them an excellent investment for multi-vehicle collections.

Technical Performance

The 6x12x4mm bearing dimensions represent a standard size used throughout the Traxxas RC vehicle lineup, from high-performance brushless electric monster trucks to dedicated 4x4 rock crawlers. The black rubber seal technology represents a genuine engineering advancement over earlier blue-seal designs. Where blue-seal bearings provide basic protection, black-seal bearings feature a tighter, more effective seal that creates a superior barrier against the harsh conditions RC vehicles encounter. Dirt, sand, water, and mud are common enemies of bearing longevity — the black seal minimises ingress of these contaminants, preserving the bearing's internal lubricant and the critical ball-to-race contact surfaces for much longer periods. This engineering improvement directly translates into extended bearing lifespan, reduced maintenance frequency, and more reliable performance during crucial moments at the track or during outdoor bashing sessions. The precision manufacturing ensures minimal runout and perfectly smooth rotation, which is essential for maintaining accurate steering response and consistent handling feel in vehicles like the Stampede 4X4 HD VXL brushless monster truck or TRX-4 trail crawler platforms.

Frequently Asked Questions

• What is the difference between black-seal and blue-seal bearings for RC cars? — Black-seal bearings feature an even tighter seal compared to blue-seal alternatives, offering superior protection against dirt and moisture. This enhanced sealing makes black-seal bearings ideal for dirty environments and reduces maintenance requirements significantly. If you regularly bash your RC car in muddy or dusty conditions, black-seal bearings are the better choice for long-term reliability.
• Which Traxxas models use 6x12x4mm bearings? — These bearings are compatible with a wide range of Traxxas vehicles including the Stampede 4X4 HD VXL brushless electric monster truck (available in green, orange, and blue), multiple TRX-4 crawler variants including the Chevrolet K10 Cheyenne, Ford F-150 Ranger XLT, Chevrolet K5 Blazer, Chevy Blazer, Nissan Pathfinder, Ford Bronco, and Defender models, as well as TRX-4 Sport models. Check your vehicle's manual for specific bearing locations.
• How often should I replace my RC bearing seals? — Bearing replacement frequency depends on usage conditions and maintenance habits. If you regularly run in dirty or wet environments, you may need to replace bearings every 20-30 hours of use. Black-seal bearings extend this interval considerably compared to unsealed or blue-seal alternatives. Regular inspection is recommended — if you notice grinding noises or sloppy steering response, it's time to replace your bearings.
• Are these genuine Traxxas factory parts? — Yes, these are official Traxxas OEM (original equipment manufacturer) components bearing the part number TRX5117A. Using genuine Traxxas bearings ensures perfect fitment, maintains your vehicle's warranty, and guarantees the performance and durability specifications set by the manufacturer.
• Can I use these bearings on multiple Traxxas vehicles? — Absolutely. The 6x12x4mm size is a standard across many Traxxas models, so if you own multiple vehicles in your collection, you can potentially use these bearings across different platforms. However, always consult your specific vehicle's manual to confirm bearing sizes and quantities needed.
• What should I do if my bearings are worn or contaminated? — If your bearings are grinding, squeaking, or causing steering to feel loose and unresponsive, they need replacement. Simply remove the old bearings and press in the new ones. Never attempt to clean and reuse heavily contaminated bearings — fresh bearings provide better performance and reliability, and the small cost is justified by improved handling.
