Traxxas Ball Bearings Black Rubber Sealed 5x8x2.5mm Pair TRX5114A

Overview

The Traxxas Ball Bearings, Black Rubber Sealed (5x8x2.5mm) (2 pcs) TRX5114A represent a significant upgrade for any serious RC car enthusiast in the UK looking to enhance their vehicle's performance and longevity. These premium-quality ball bearings are engineered to deliver smooth, precise rotation whilst offering exceptional durability in demanding conditions. Whether you're running a ready to run RC crawler, a brushless RC monster truck, or any Traxxas model that utilises these bearing sizes, upgrading to black-seal bearings is a smart investment that will keep your RC vehicle running smoothly for years to come.

Black-seal ball bearings represent the pinnacle of Traxxas bearing technology, sitting a step above the standard blue-seal offerings. The enhanced rubber seal design provides an even tighter barrier against dirt, moisture and debris, making these bearings particularly valuable for RC enthusiasts who regularly bash their vehicles in challenging outdoor environments. If you're serious about maintaining peak performance in your RC car, truck or crawler, these sealed bearings are an essential upgrade that will reduce maintenance intervals and extend the service life of your drivetrain components significantly.

Designed for compatibility with a wide range of Traxxas RC vehicles—from the Slash Ultimate 4x4 VXL short course truck to the massive Sledge belted 1/8 4WD brushless electric monster truck, as well as multiple TRX-4 crawler variants and the Unlimited Desert Racer—these bearings offer universal compatibility across Traxxas's most popular RC models. For RC car owners in the UK seeking genuine replacement parts and performance upgrades, the TRX5114A is an authentic Traxxas component that delivers OEM quality and reliability.

Key Features

• Black Rubber Seal Technology — The black-seal design provides a noticeably tighter seal compared to standard blue-seal bearings, offering ultimate protection against contaminants and significantly reducing the ingress of dirt, sand, and moisture into the bearing race and rolling elements, which directly extends bearing life and maintains smoother performance over extended use periods.
• Superior Dirty Environment Performance — Rubber-sealed ball bearings are specifically engineered for RC vehicles that operate in dirt environments, providing exceptional protection that ensures your bearings maintain their smoothness and precision even after hours of outdoor bashing and play, eliminating the need for frequent bearing replacement.
• Reduced Maintenance Requirements — The enhanced sealing system means you'll spend less time cleaning and maintaining your RC vehicle's drivetrain, allowing you to focus more on driving and enjoying your hobby rather than performing constant upkeep on exposed bearing surfaces.
• Smooth, Long-Lasting Performance — These precision-engineered ball bearings deliver silky-smooth rotation that translates directly into improved handling, faster acceleration response and more reliable operation throughout your RC vehicle's suspension, drivetrain and steering components.
• Precise Driving Dynamics — The tight tolerances and high-quality steel construction ensure that rotational dynamics remain consistent and predictable, providing the level of precision that competitive RC drivers and serious hobbyists demand from their equipment.
• Genuine Traxxas Component — As official Traxxas parts (part number 5114A), these bearings meet the manufacturer's exacting quality standards and are designed to perfectly match the specifications of your Traxxas RC vehicle, ensuring flawless fitment and performance.

Technical Performance

The 5x8x2.5mm bearing dimensions represent a standard size used throughout the Traxxas product range, particularly in vehicles like the TRX-4 series crawlers, the Sledge 1/8 scale monster truck, and the legendary Slash Ultimate 4x4 VXL short course truck. These bearings feature precision-ground steel races and high-quality chrome steel ball elements that maintain their rotational properties even under the demanding stresses of high-performance RC driving. The black rubber seal construction utilises elastomeric materials that create a contact seal around the outer race, which actively prevents contamination while remaining loose enough to maintain smooth rotation without generating excessive friction. This engineering represents Traxxas's commitment to delivering components that balance protection with performance. The bearing pack includes two individual bearing units, allowing you to replace a pair of bearings in critical drivetrain locations or to stock spare parts for future maintenance. Whether you're running these bearings in a crawler navigating rocky terrain, a short course truck hitting high speeds across dirt tracks, or a monster truck performing aerial stunts, the sealed design ensures consistent performance whilst minimising the wear patterns that can develop when dirt accumulates inside open bearings. The sealed design also means you can run your RC vehicle immediately after wet conditions without waiting for bearings to dry, as water ingress is effectively prevented by the rubber seals.

Frequently Asked Questions

• Are black-seal bearings better than blue-seal bearings for my RC car? — Yes, black-seal bearings provide a tighter seal and offer superior protection against dirt and contamination compared to blue-seal bearings. Traxxas engineers designed black-seal bearings specifically to sit a step above blue-seal offerings, making them the better choice if you regularly bash your RC vehicle in dirty outdoor environments or want to minimise maintenance intervals and extend bearing life.
• Which Traxxas models are compatible with the TRX5114A bearings? — These 5x8x2.5mm bearings are compatible with an extensive range of Traxxas models including the Slash Ultimate 4x4 VXL 1:10 4WD brushless short course truck, the Sledge Belted 1:8 4WD brushless electric monster truck in multiple colour options, all TRX-4 variants including the Chevrolet K10 Cheyenne High Trail Edition, the Ford F-150 Ranger XLT High Trail Edition crawler, the 1972 Chevrolet K5 Blazer High Trail Edition, the 1979 Chevy Blazer 1:10 4x4 electric all-terrain crawler, the Nissan Pathfinder SE-V6 3S 4x4 RTR, the 2021 Ford Bronco 1/10 crawler, the TRX-4 Defender 4WD RTR, the TRX-4 Sport, and the UDR Unlimited Desert Racer Pro-Scale 4WD RTR short course truck.
• Why should I replace my open or blue-seal bearings with black-seal bearings? — Rubber-sealed ball bearings provide protection that translates into smooth, long-lasting and precise driving, especially in dirt environments. By upgrading to black-seal bearings, you'll experience reduced maintenance requirements, fewer dirt particles infiltrating your drivetrain, longer intervals between cleaning and bearing replacement, and ultimately superior performance and reliability from your RC vehicle.
• Do sealed bearings slow down my RC car? — No. The black rubber seals are engineered to maintain smooth rotation without introducing significant friction. Any minimal friction from the seal design is far outweighed by the benefits of reduced dirt ingestion and longer-term bearing smoothness, meaning your RC vehicle will actually perform better over an extended usage period compared to using unsealed or poorly sealed bearings that accumulate contamination.
• How many bearings do I get in this pack? — This pack includes 2 individual ball bearings, allowing you to replace a pair of bearings in critical drivetrain locations such as the front and rear differentials, or to maintain a stock of spares for future maintenance and upgrades to your RC vehicle.
• Are these genuine Traxxas parts? — Yes, these are authentic Traxxas components manufactured to OEM specifications with part number 5114A. Purchasing genuine Traxxas bearings ensures perfect compatibility, reliable performance, and the assurance that you're installing components designed and tested specifically for your Traxxas RC vehicle.
