Traxxas Ball Bearing Black Rubber Sealed Stainless 5x11x4mm Pair TRX5116X

Overview

The Traxxas Ball Bearings in black rubber sealed, stainless steel construction represent a premium choice for RC enthusiasts across the UK who demand reliability and durability from their RC car components. Whether you're a seasoned competitor running a high-performance RC buggy or a weekend basher pushing your RC truck to the limit, these precision ball bearings are engineered to withstand the demands of serious RC racing and off-road driving. These 5x11x4mm bearings deliver the performance and protection that experienced RC hobbyists expect when upgrading or maintaining their vehicles.

Black-seal bearings occupy a special position in the Traxxas bearing lineup, sitting a step above the standard blue-seal alternatives. This elevation in specification means you get an even tighter seal for ultimate protection against dirt, dust, water and debris—making these bearings particularly valuable if you frequently race in wet conditions or muddy environments where contaminants can compromise bearing performance. The stainless steel construction resists corrosion and oxidation, ensuring your investment maintains its integrity over extended periods of use, whether your RC car spends time on tarmac circuits, dusty off-road tracks, or in damp British weather conditions.

Supplied as a pair (2 pieces), these replacement bearings are ready to install and offer a straightforward upgrade path for RC car owners looking to improve reliability, reduce maintenance intervals, and achieve smoother, faster rotation across your model's drivetrain. From RC monster trucks to RC buggies and everything in between, quality bearings like these from Traxxas are essential components that directly influence handling, speed consistency and overall driving experience.

Key Features

• Black Rubber Seal Design — The black rubber seals provide an exceptionally tight closure compared to standard blue-seal bearings, creating a superior barrier against environmental contaminants, water ingress and dirt accumulation that can cause premature wear and loss of performance.
• Stainless Steel Construction — The use of stainless steel resists rust, corrosion and oxidation, ensuring these bearings maintain their performance characteristics even when exposed to wet conditions, salt air or high-humidity storage environments typical in the UK climate.
• Ultimate Protection Rating — These bearings are engineered for situations where maximum protection and minimal maintenance are priorities, making them ideal for serious racers and bashers who demand reliability without constant servicing.
• Reduced Maintenance Requirements — The advanced seal design means you'll spend less time cleaning and re-lubricating your bearings between sessions, allowing you to spend more time enjoying your RC hobby and less time on workshop duties.
• Precision Ball Bearing Construction — Each bearing features precisely manufactured balls and races that enable smooth, efficient rotation with minimal friction loss, directly translating to better acceleration response and top-end speed potential.
• Pair Supply — Delivered as a matched pair of two bearings, these come ready to install and are suitable for applications requiring dual bearing configurations across RC vehicle platforms.
• 5x11x4mm Dimensions — This specific size is widely compatible across popular RC car models and platforms, making these bearings a reliable upgrade option for owners of various Traxxas vehicles and compatible RC cars from other manufacturers.

Technical Performance

These Traxxas black-seal stainless ball bearings represent a significant step forward in bearing technology for RC enthusiasts. The combination of stainless steel materials with advanced black rubber sealing creates a bearing assembly capable of operating reliably in challenging conditions where standard blue-seal variants would require more frequent maintenance. The 5x11x4mm specification indicates an internal bore of 5mm, an outer diameter of 11mm, and a width of 4mm—dimensions that suit a wide range of RC car applications. The stainless steel construction provides superior corrosion resistance compared to standard steel bearings, particularly important for users in the UK where humidity and wet weather conditions are common. The black rubber seal technology creates a barrier that is tighter and more effective than blue-seal alternatives, significantly reducing water and debris ingress whilst maintaining smooth rotational characteristics. These bearings are manufactured to precise tolerances ensuring consistent performance across matched pairs, critical for vehicles where bearing variations can cause handling inconsistencies or drivetrain vibration. Whether installed in the rear axles, front hubs, transmission shafts or other drivetrain components, these bearings will deliver the smooth, reliable performance that serious RC car owners demand. The advanced sealing design means longer intervals between maintenance procedures, allowing you to maximise your RC driving time without constant bearing servicing. Installation is straightforward—simply remove worn bearings and press these new units into position using appropriate bearing pullers and installers available from any RC specialist retailer.

Frequently Asked Questions

• What is the difference between black-seal and blue-seal Traxxas bearings? — Black-seal bearings offer an even tighter seal for ultimate protection compared to blue-seal variants. This means better protection against water, dirt and debris, particularly valuable if you race your RC car in wet conditions or muddy environments. The superior sealing also means less frequent maintenance is required, allowing you to enjoy longer periods between bearing servicing.
• Are stainless steel bearings worth the extra cost? — Yes, particularly if you use your RC car frequently or in challenging conditions. Stainless steel resists corrosion and oxidation that can compromise bearing performance over time, ensuring your investment maintains its characteristics across extended periods. For serious RC hobbyists and competitors, the reliability benefits justify the additional cost.
• Will these bearings fit my RC car? — The 5x11x4mm size is widely compatible across popular RC car platforms and Traxxas vehicles. However, you should verify the bearing size specification for your particular model before ordering. Check your vehicle's manual or consult with RC Model Shop staff to confirm compatibility with your specific RC car.
• How often should I service bearings with black-seal design? — The advanced seal design means you'll require less frequent servicing compared to standard bearings. However, if you race in particularly dirty or wet conditions, periodic cleaning and light re-lubrication may still be beneficial. The exact interval depends on your usage patterns and environmental conditions.
• Can I install these bearings myself? — Yes, bearing installation is a straightforward task for most RC enthusiasts with basic tools. You'll need an appropriate bearing puller to remove old bearings and a bearing installer or press to fit the new units. Many RC Model Shop customers handle this task themselves, though professional installation is also available if preferred.
• Are these suitable for high-speed racing applications? — Absolutely. These bearings are engineered for performance-oriented applications and are suitable for competition RC racing where smooth, efficient rotation is essential for speed consistency and handling precision. The precision-manufactured construction ensures minimal friction and vibration.
