Traxxas Ball Bearings 5x11x4mm Blue Rubber Sealed 2 Piece TRX5116

Overview

The Traxxas Ball Bearings in 5x11x4mm size with blue rubber seals are essential maintenance components for RC enthusiasts across the UK who demand smooth, reliable performance from their RC vehicles. Whether you're running a Traxxas 4TEC 3.0, Rustler, Slash, X-Maxx, XRT or TRX-4 crawler, these precision-engineered bearings are designed to replace worn or damaged originals and restore your RC car to factory condition. This pack contains two ball bearings, which is typically the quantity needed for a single axle or drivetrain component, making it a practical and cost-effective spare part for serious RC hobbyists and weekend bashers alike.

Ball bearings are the backbone of smooth, efficient RC performance, and the quality of your bearings directly affects how your model handles, accelerates and maintains speed. The blue rubber seal design of these Traxxas OEM bearings represents a significant upgrade over older unsealed designs, offering protection against dust, dirt, sand and moisture that can accumulate during outdoor RC driving sessions. Choosing genuine Traxxas replacement bearings ensures perfect compatibility with your model and maintains the engineering standards that Traxxas built into your vehicle from the factory.

If you're looking to upgrade your RC car's drivetrain performance, extend the life of your transmission and suspension components, or simply replace bearings that have become worn after heavy use, these 5x11x4mm blue rubber sealed bearings are exactly what you need. They're compatible with an impressive range of Traxxas models including high-performance vehicles like the 4TEC 3.0 Chevrolet Corvette Stingray, the Ford Fiesta ST Rally BL-2S, the Funco Motorsports Pro Scale 8S sand car, and numerous TRX-4 crawler variants in their different colours and editions.

Key Features

• Blue Rubber Seal Design — The blue rubber seals form a protective barrier around the bearing races, actively keeping out dust, grime, sand and moisture that would otherwise infiltrate and damage the bearing surfaces. This sealed design means you'll spend less time performing maintenance and more time enjoying your RC car, as the seals significantly reduce the rate of contamination compared to unsealed bearings.
• Reduced Friction and Smoother Running — Clean, well-maintained bearings with effective sealing create lower resistance in the drivetrain, allowing your motor power to be transmitted more efficiently to the wheels. This translates to smoother acceleration, more predictable handling, and better overall responsiveness, especially noticeable when comparing freshly installed sealed bearings to aged unsealed components.
• Less Maintenance Required — Because the blue rubber seals exclude contaminants far more effectively than open designs, you won't need to clean and re-oil your bearings as frequently. This reduces your overall maintenance burden and keeps your RC car performing at peak efficiency for longer periods between service intervals.
• Genuine Traxxas OEM Component — These are official Traxxas factory-specification bearings, meaning they meet exactly the engineering tolerances and performance standards that Traxxas designed into your vehicle. Using genuine OEM parts ensures perfect fit, proper clearances, and compatibility with all other factory components in your model.
• 5x11x4mm Metric Size Specification — This specific bearing size is engineered for use in Traxxas driveline, suspension and transmission applications, with the 5mm inner diameter, 11mm outer diameter and 4mm width providing the precise fit required for optimal performance in these critical locations on your RC vehicle.
• Pair of Two Bearings — This pack contains two bearings, which is the standard quantity needed for replacing a full axle set or drivetrain component, making this a complete solution for a single upgrade job without requiring multiple packs.

Technical Performance

These ball bearings represent precision engineering at its finest, manufactured to exacting tolerances by Traxxas to deliver consistent, reliable performance across a wide range of RC vehicles from high-speed stadium trucks and short-course trucks to rock crawlers and scale trail vehicles. The 5x11x4mm dimensions have been specifically chosen to fit critical drivetrain locations where bearing performance directly impacts acceleration, top speed, responsiveness and durability. The blue rubber seals are engineered to remain flexible and effective even in cold UK weather conditions and after repeated exposure to moisture from damp grass, wet tracks or morning dew. The sealed design maintains lubrication within the bearing races whilst preventing external contaminants from entering, creating an optimal micro-environment for smooth rotation. The quality of the ball races and the precision of the manufacturing process ensure that these bearings maintain their smooth running characteristics throughout thousands of operating hours, whether you're bashing through rough terrain, racing competitively, or performing controlled manoeuvres in a crawling scenario. Upgrading to new sealed bearings is one of the most cost-effective performance improvements available to RC enthusiasts, as worn bearings increase friction throughout the drivetrain, requiring your battery to deliver more current to achieve the same speeds, reducing runtime and increasing heat generation in your motor and ESC.

Frequently Asked Questions

• What Traxxas RC vehicles are these bearings compatible with? — These 5x11x4mm blue rubber sealed bearings are compatible with an extensive range of Traxxas models including the 4TEC 3.0 Chevrolet Corvette Stingray in both black and silver versions, Ford Fiesta ST Rally BL-2S in red and VXL in green, Funco Motorsports Pro Scale 8S sand cars in red, blue, orange and green, Rustler Ultimate VXL 4x4 in green and blue, Slash Ultimate 4x4 VXL, Slash VXL 4x4 RTR in multiple colours, Slash HD XL-5 in various finishes, the complete TRX-4 range including Chevrolet K10 Cheyenne variants, Ford F-150 Ranger XLT, Chevrolet K5 Blazer editions, Nissan Pathfinder SE-V6, Ford Bronco, Defender models, and both the X-Maxx and XRT ultimate scale vehicles. If you're unsure whether your specific model uses this bearing size, consult your vehicle's parts diagram or contact our team of RC experts at RC Model Shop.
• Why should I upgrade to blue rubber sealed bearings? — Factory-original or older unsealed bearings allow dust, dirt and moisture to freely enter and contaminate the bearing races, causing increased friction, reduced efficiency and requiring frequent cleaning and re-lubrication. Blue rubber sealed bearings keep these contaminants out through their protective seal design, meaning you'll enjoy smoother running, less maintenance, better acceleration and longer bearing life. For UK RC enthusiasts who drive in varied outdoor conditions including damp grass and muddy terrain, sealed bearings are particularly valuable as they resist moisture ingress far more effectively than open designs.
• How often should I replace these bearings? — With proper care and the contamination protection offered by the blue rubber seals, these bearings should provide thousands of hours of reliable service. However, if you notice increased friction in your drivetrain, sluggish acceleration, or rough running despite fresh lubrication, it's time to replace them. Regular inspection during routine maintenance will reveal when bearings need replacement.
• Are these genuine Traxxas parts? — Yes, the TRX5116 is an official Traxxas OEM part number, ensuring you're receiving genuine factory components that meet Traxxas' engineering specifications and quality standards. When purchasing from RC Model Shop, you can be confident you're buying authentic products directly from an authorised retailer.
• What is the difference between sealed and unsealed bearings? — Unsealed bearings offer slightly lower rotational resistance but allow contaminants and moisture to enter freely, requiring frequent maintenance and reducing service life. Sealed bearings, like these blue rubber designs, sacrifice minimal performance for dramatically improved longevity, reduced maintenance and reliable operation in diverse weather conditions, making them the preferred choice for most RC enthusiasts.
