Traxxas Ball Bearings Blue Rubber Sealed 8x12x3.5mm TRX7020

Overview

The Traxxas Ball Bearings, Blue Rubber Sealed (8x12x3.5mm) (2 pcs) TRX7020 are essential spare parts for maintaining and upgrading your RC car, truck, or buggy. Whether you're a serious RC enthusiast in the UK looking to keep your brushless RC monster truck or short course truck running at peak performance, or a weekend basher who wants to reduce maintenance on your ready to run RC vehicle, these blue-seal ball bearings offer a proven solution for smoother operation and extended component lifespan. As a UK RC car owner, you'll appreciate the practical benefits these bearings bring to your hobby setup.

Designed and manufactured by Traxxas, one of the world's most trusted names in RC vehicles and spare parts, these ball bearings are engineered to keep your RC model running smoothly regardless of whether you're driving a 1/16 scale E-Revo, a 1/8 Maxx Slash short course truck, or any of the numerous other Traxxas models listed as compatible. The blue rubber seal design sets these bearings apart from unsealed alternatives, providing a protective barrier that keeps dust, dirt, grime and moisture out of the critical bearing surfaces. This sealed design means less frequent maintenance, reduced friction during operation, and ultimately better performance and longer bearing life for your RC car UK setup.

These are genuine OEM Traxxas bearings that come as a pair, ready to install into your RC vehicle. If you're maintaining a fleet of RC vehicles or regularly compete in RC racing events, having spare sealed bearings on hand is essential practice. The blue rubber seals are instantly recognisable and mark these as premium components designed for serious RC hobbyists who demand reliability and longevity from their spare parts.

Key Features

• Blue Rubber Sealed Design — The blue rubber seals create a protective barrier around the bearing surfaces, keeping out dust, dirt, grime and moisture that would otherwise cause premature wear and increase friction during operation. This is particularly important for RC cars and trucks driven outdoors on dusty terrain or in damp conditions.
• Reduced Maintenance Requirements — By preventing contaminants from entering the bearing, the sealed design means you'll spend less time cleaning and maintaining your RC vehicle. This translates directly into more time actually driving your model.
• Smoother Running Performance — Clean, well-protected bearings operate with minimal friction, resulting in smoother rotation of wheels, gears, and other rotating components. This contributes to better handling, improved acceleration, and overall more responsive vehicle control.
• Less Friction — The sealed bearing design maintains optimal lubrication levels inside the bearing chamber, ensuring friction remains at a minimum throughout the bearing's service life. Lower friction means better efficiency and less energy loss during operation.
• Genuine Traxxas OEM Parts — These are authentic original equipment manufacturer bearings designed and produced by Traxxas specifically for their vehicles, ensuring perfect compatibility and reliability.
• Supplied as a Pair — This pack contains two bearings, allowing you to replace both bearings in a single location or to maintain spare parts inventory for future maintenance needs on your RC vehicle.
• Wide Compatibility — These 8x12x3.5mm bearings are compatible with a comprehensive range of Traxxas models including the E-Revo VXL 1/16 brushless monster truck, the Slash 1/16 short course truck, the Maxx Slash 1/8 brushless truck, the UDR Unlimited Desert Racer pro-scale truck, and the WideMaxx monster truck in all colour variants.

Technical Performance

The Traxxas TRX7020 ball bearings measure 8x12x3.5 millimetres and utilise precision-engineered steel balls housed in a carefully designed bearing race. The blue rubber seals are engineered to maintain consistent contact with the outer and inner bearing races, creating an effective seal that keeps contaminants out whilst allowing the bearing to spin freely with minimal resistance. This is critical engineering because unsealed bearings would accumulate dirt and grime that would increase friction, generate heat, and cause rapid wear of both the balls and the races. The sealed design is particularly beneficial for RC bashers who drive their vehicles on dusty tracks, sandy terrain, or in wet conditions common in the UK climate. The materials used in these bearings are selected for durability and consistent performance across the temperature ranges and operating speeds encountered in modern RC vehicles, whether you're driving a competitive brushless RC truck at high speeds or casually bashing your ready to run RC car through rough terrain. Many experienced RC hobbyists keep multiple sets of these bearings in their spares box as they are wear items that require periodic replacement to maintain optimal vehicle performance. The precision manufacturing tolerances ensure that these bearings will fit perfectly into the bearing pockets of compatible Traxxas vehicles without any wobbling or play, which is essential for maintaining accurate steering, suspension geometry, and drivetrain efficiency.

Frequently Asked Questions

• What is the difference between sealed and unsealed bearings for RC cars? — Sealed bearings like the Traxxas TRX7020 feature rubber seals on both sides that prevent dust, dirt, and moisture from entering the bearing cavity. Unsealed bearings offer lower friction but require more frequent cleaning and maintenance. For UK RC drivers who use outdoor tracks or bash in dusty conditions, sealed bearings are generally the better choice as they reduce maintenance and provide longer service life.
• Are these bearings compatible with my Traxxas RC vehicle? — These 8x12x3.5mm sealed bearings are compatible with a wide range of Traxxas models including the E-Revo VXL 1/16 in blue and purple, the Slash 1/16 in black, the Maxx Slash 1/8 in rock n roll, blue, red and green variants, the UDR Unlimited Desert Racer with Rigid Industries and Fox Racing packages, and the WideMaxx monster truck in red, rock n roll and green. If your model is listed as compatible, these bearings will fit perfectly.
• How often should I replace the bearings on my RC car? — The lifespan of bearings depends heavily on driving conditions and maintenance practices. Sealed bearings like these typically last longer than unsealed alternatives, especially when driven in dusty or wet conditions. If you notice your RC vehicle developing grinding noises, excessive play in wheels or drivetrain components, or reduced responsiveness, it's time to inspect and potentially replace the bearings.
• Can I use these bearings in other RC brands or models? — Whilst these are Traxxas-manufactured bearings designed for Traxxas vehicles, the 8x12x3.5mm size is a relatively common bearing dimension. However, we recommend only using these bearings in compatible Traxxas models to ensure proper fit and performance. Using incorrect bearings could result in poor fit, excessive wear, and potential vehicle damage.
• What makes these blue rubber sealed bearings different from standard bearings? — The blue rubber seal design is specifically engineered to create an effective barrier against contaminants whilst maintaining smooth rotation. The seals are designed to wear in gradually and maintain contact with the bearing races throughout the bearing's service life, providing consistent protection. This makes them ideal for RC enthusiasts who want to minimise maintenance and maximise performance.
• Are these suitable for competitive RC racing? — Yes, many competitive RC racers in the UK use sealed bearings like the Traxxas TRX7020 because they provide consistent performance throughout a race day without requiring frequent servicing between heats. Having fresh, clean bearings in your RC car contributes to predictable handling and optimal vehicle response.
