FTX Ball Bearing 3.5x7x2.5mm Plastic Cover RC Spare Part FTX-BB009

Overview

The FTX Ball Bearing (3.5*7*2.5) with plastic cover is an essential replacement and upgrade component for RC enthusiasts across the UK. Whether you're maintaining your RC car UK setup, upgrading your ready to run RC vehicle, or building a custom RC model, these precision ball bearings are critical to ensuring smooth, reliable performance. Ball bearings are fundamental to the operation of any RC vehicle, reducing friction in wheels, differentials, and drivetrain components whilst distributing loads evenly across their rolling elements.

This specific bearing measures 3.5mm inner diameter by 7mm outer diameter with a 2.5mm width, making it compatible with a wide range of FTX RC models and many other RC platforms. The plastic cover design provides protection against dirt, dust, and debris whilst maintaining optimal performance in both on-road and off-road conditions. For competitive racers, weekend bashers, and hobbyists alike, having high-quality replacement bearings on hand is essential for maintaining peak performance and extending the lifespan of your RC vehicle.

When bearings begin to wear, you'll notice increased friction, reduced top speed, and difficulty in precise cornering. Replacing worn bearings with genuine FTX components restores your RC vehicle to factory performance standards. The plastic cover helps seal out contaminants that can cause premature wear, making this bearing an excellent choice for rough terrain and challenging driving conditions. Stock these genuine FTX ball bearings in your RC spare parts collection and ensure your vehicles always perform at their best.

Key Features

• Precision ball bearing design — The 3.5*7*2.5 dimensions provide optimised rolling action that reduces friction in critical drivetrain and wheel components, allowing your RC vehicle to achieve faster acceleration and smoother handling characteristics.
• Plastic cover protection — The protective plastic shield helps prevent dirt, dust, water and other contaminants from entering the bearing assembly, which significantly extends bearing lifespan and maintains consistent performance across multiple driving sessions.
• OEM FTX specification — As a genuine FTX component, this bearing meets the original equipment manufacturer specifications and is designed to work seamlessly with FTX RC vehicles including the FTX Banzai, FTX Bugsta, FTX Carnage, FTX Colt, FTX Comet, FTX DR8, FTX Edge, FTX EVO30, FTX Hi-Rock, FTX Kanyon, FTX Mauler, FTX Mighty Thunder, FTX Mini Outback, FTX Outback 2.0, FTX Outback Fury, FTX Outback Mini XP Evo, FTX Outlaw, FTX Ravine, FTX Siege, FTX Stinger, FTX Tracer, FTX Vantage and numerous other FTX models.
• Easy installation — These ball bearings are straightforward to install in standard bearing housings, making them ideal for quick maintenance and repairs without requiring specialist tools or extensive mechanical knowledge.
• Smooth rolling action — Precision manufactured ball bearings provide consistent, reliable rotation with minimal resistance, which translates to improved vehicle responsiveness and better overall handling dynamics.
• Universal compatibility — Whilst designed for FTX models, the 3.5*7*2.5 size is a common bearing specification used across many RC platforms and brands, making these bearings versatile spares for various RC vehicles.

Technical Performance

Ball bearings are the backbone of smooth RC vehicle performance, and the FTX BB009 represents a precision-engineered component built to exacting standards. The bearing's inner diameter of 3.5mm accommodates standard RC axles and shafts, whilst the 7mm outer diameter provides optimal load distribution across wheel hubs and drivetrain components. The 2.5mm width is specifically engineered to fit tight spaces within RC vehicle architecture without compromising load-carrying capacity. Each bearing contains multiple hardened steel balls held in a cage, which roll against precision-ground races to minimise friction and maximise rotational efficiency. The plastic cover design uses durable polymeric materials that provide effective sealing against environmental contaminants whilst remaining lightweight to avoid adding unnecessary weight to your RC vehicle. These ball bearings are manufactured to tolerances tight enough to ensure consistent performance across multiple vehicles and driving conditions. When properly installed and maintained, FTX ball bearings deliver smooth, responsive handling and help your RC car UK perform at peak efficiency whether you're tackling tight slalom courses or aggressive off-road terrain. The plastic cover is particularly valuable in wet or dusty conditions, as it prevents water ingress and debris accumulation that would otherwise cause premature bearing failure and degradation of vehicle performance.

Frequently Asked Questions

• What FTX RC models use the FTX-BB009 ball bearing? — The FTX-BB009 is compatible with numerous FTX RC vehicles, including the FTX Banzai, FTX Bugsta, FTX Carnage NT, FTX Carnage, FTX Colt, FTX Comet, FTX DR8, FTX Edge, FTX EVO30, FTX Hi-Rock, FTX Kanyon, FTX Mauler, FTX Mighty Thunder, FTX Mini Outback, FTX Outback 2.0, FTX Outback Fury, FTX Outback Mini XP Evo, FTX Outback, FTX Outlaw, FTX Ravine, FTX Siege, FTX Stinger, FTX Tracer, FTX Vantage and many other FTX models across their range of ready to run RC vehicles and hop-up parts.
• Why do ball bearings need to be replaced? — Over time and with extended use, the rolling elements within ball bearings experience wear, the lubricant degrades, and contaminants can accumulate causing friction and resistance. Replacing worn bearings restores smooth operation, improves vehicle responsiveness, and helps maintain top speed and handling characteristics. The plastic cover on these bearings helps slow degradation by protecting against dirt and moisture, but regular maintenance and replacement when needed is essential for optimal RC performance.
• How often should I replace bearings on my RC vehicle? — The replacement frequency depends on driving intensity, terrain conditions, and maintenance practices. Bearings used in off-road or wet conditions may require more frequent replacement than those in controlled, dry environments. If you notice increased friction, reduced speed, or difficulty turning, it's time to replace your bearings. Keeping spare bearings like the FTX-BB009 in your RC hobby toolbox means you can perform maintenance immediately without waiting for delivery.
• What's the difference between plastic cover and metal shield bearings? — The FTX-BB009 features a plastic cover that provides excellent protection against dirt and debris whilst remaining lightweight. Metal shields offer slightly more robust protection but add marginal weight. For most RC driving conditions in the UK, the plastic cover design strikes an ideal balance between protection, performance and vehicle weight, making it suitable for both casual bashers and serious racers.
• Are these genuine FTX parts? — Yes, the FTX-BB009 is an official FTX spare part manufactured to original equipment manufacturer specifications. When you purchase from RC Model Shop, you receive genuine FTX components that are guaranteed to fit your vehicles correctly and perform reliably.
• Can I use these bearings in non-FTX RC vehicles? — The 3.5*7*2.5 ball bearing is a standard size used across many RC brands and platforms. If your ready to run RC vehicle or custom build uses this bearing size, the FTX-BB009 should be compatible. Always verify bearing specifications in your vehicle's manual or parts diagram before purchasing replacements.
