FTX Ball Bearing 8x12x3.5mm Plastic Cover RC Spare FTX-BB012

Overview

The FTX Ball Bearing (8*12*3.5) with plastic cover is an essential spare part for RC enthusiasts across the UK who demand reliable performance from their radio-controlled vehicles. Whether you're running an FTX RC car, crawler, buggy or other RC model, quality ball bearings are critical components that directly impact your vehicle's speed, handling and longevity. This precision-engineered bearing is designed to replace worn or damaged bearings in your RC setup, ensuring smooth rotation and optimal performance during every run at the track or off-road terrain.

Ball bearings are fundamental to RC vehicle performance, reducing friction in rotating components and allowing your motors, wheels and drivetrain to operate at peak efficiency. When bearings wear out or become damaged through normal use, they create drag, reduce responsiveness and can cause premature wear to other components. The FTX Ball Bearing (8*12*3.5) is manufactured to exacting standards by FTX, a recognised brand trusted by RC enthusiasts throughout the United Kingdom. This bearing features a durable plastic cover that protects the internal ball races from dirt, debris and moisture while maintaining smooth operation in various racing and bashing conditions.

Whether you're a competitive racer seeking to maintain your vehicle's performance specifications, a weekend basher who wants reliable spares on hand, or an RC hobbyist building or upgrading your setup, having quality replacement bearings in your spares box is essential. The FTX Ball Bearing (8*12*3.5) offers excellent value for money and is readily available for UK customers through RC Model Shop, ensuring you can keep your RC vehicles running at their best.

Key Features

• Precision Ball Bearing Construction — This bearing features precision-engineered steel balls held in a cage that reduces friction and provides smooth, consistent rotation. Quality ball bearings are essential for optimal RC vehicle performance, as they directly affect acceleration, top speed, and handling characteristics.
• Plastic Cover Protection — The durable plastic cover shields the internal bearing races from dirt, sand, mud and moisture that would otherwise degrade performance or cause premature failure. This protective design extends bearing life and maintains reliable operation in outdoor racing and bashing conditions across UK terrain.
• 8*12*3.5mm Specifications — These precise dimensions (8mm inner diameter, 12mm outer diameter, 3.5mm width) are engineered for compatibility with FTX RC vehicles and other similarly-sized drivetrain components. The compact size makes this bearing ideal for high-speed applications where weight and space are critical factors.
• OEM Quality Standards — Manufactured by FTX to original equipment specifications, this bearing meets the exacting standards required for reliable RC performance. You can trust that replacement bearings from the original manufacturer will maintain your vehicle's performance characteristics.
• Cost-Effective Spare Part — Rather than replacing an entire assembly, a single bearing replacement restores performance and extends the life of your RC vehicle. This targeted maintenance approach is more economical than wholesale component replacement.
• Universal RC Application — This bearing size is used across numerous FTX RC models including crawlers, buggies, trucks and other vehicles. Having quality replacement bearings ensures you can service multiple vehicles or keep your current model running smoothly.

Technical Performance

The FTX Ball Bearing (8*12*3.5) represents essential maintenance and upgrade hardware for serious RC enthusiasts in the UK. Ball bearings are precision components that support rotating shafts and reduce friction throughout your RC vehicle's drivetrain, suspension and wheel assemblies. The 8mm inner diameter and 12mm outer diameter make this bearing suitable for high-speed applications where smooth operation is critical for competitive performance. The 3.5mm width provides adequate load capacity while maintaining the compact dimensions necessary for modern RC vehicle design. The plastic cover is specifically engineered to keep contaminants out while allowing the bearing to operate freely—a critical balance in RC applications where vehicles are exposed to dirt, sand and moisture during outdoor use. Unlike unsealed bearings that require frequent cleaning and maintenance, the covered design reduces maintenance requirements while maintaining the smooth operation essential for track racing or off-road bashing. The internal steel ball races are hardened to exacting tolerances, ensuring each bearing rotates with minimal resistance and maximum consistency. Whether you're replacing a worn bearing that's causing drag in your driveline or upgrading to quality FTX bearings as preventative maintenance, this component will noticeably improve your vehicle's performance and handling. Quality bearings reduce vibration, improve acceleration response, and allow your RC car to reach higher top speeds with better efficiency. For competitive racers and dedicated hobbyists, maintaining your bearings in top condition is as important as proper suspension setup and tyre selection.

Frequently Asked Questions

• What is a ball bearing and why does my RC car need quality replacement bearings? — Ball bearings are precision components that support rotating shafts throughout your RC vehicle's drivetrain, suspension and wheel hubs. They reduce friction between moving parts, allowing your motor to spin wheels more efficiently and enabling your vehicle to reach higher speeds with less battery drain. When bearings wear out through normal use, they create drag that reduces performance, causes vibration and increases battery consumption. Replacing worn bearings with quality FTX replacements restores your vehicle to factory performance specifications.
• Is the FTX Ball Bearing (8*12*3.5) suitable for my RC vehicle? — This bearing is designed for FTX RC models and is compatible with any vehicle that uses 8*12*3.5mm bearings. Check your vehicle's manual or parts diagram to confirm bearing sizes before ordering. FTX manufactures a comprehensive range of RC vehicles from crawlers and buggies to trucks and short-course racers, all of which use standard bearing sizes like this one.
• How often should I replace ball bearings in my RC car? — Ball bearing replacement frequency depends on how frequently you use your vehicle and the conditions in which you operate it. Vehicles used in sandy or muddy environments may require more frequent bearing replacement than those used on clean track surfaces. Most enthusiasts inspect bearings regularly and replace any that show visible wear, rough rotation or resistance. Having spare bearings on hand allows you to perform maintenance at your convenience.
• What is the difference between plastic cover and sealed bearings? — Plastic cover bearings use a plastic shield that keeps out large debris while allowing some air circulation, making them suitable for most RC applications and easier to clean. Fully sealed bearings provide maximum protection but can trap moisture inside if not properly maintained. For most UK RC hobbyists using FTX vehicles in typical outdoor conditions, plastic cover bearings offer the best balance of protection and ease of maintenance.
• Can I use these bearings as an upgrade from my current bearings? — Yes, upgrading to quality FTX bearing replacements can improve performance if your current bearings are worn or of lower quality. Using official manufacturer bearings ensures compatibility and performance consistency across your vehicle's drivetrain.
