For anyone looking to improve steering precision, reduce play and friction, and extend the working life of their RC car's steering components, these ball bearings are an economical and highly effective upgrade.

Key Features

• Rubber sealed design — The blue rubber seals protect the internal ball bearings from dirt, dust, sand and moisture, making these bearings ideal for use in outdoor RC environments and ensuring they maintain smooth operation even in challenging UK weather conditions.
• Precision 4x7x2.5mm dimensions — These bearings are manufactured to exact specifications that ensure perfect fit and compatibility with Traxxas RC models, providing consistent performance and eliminating the play or looseness that can develop in worn plastic bushings.
• Smoother steering response — By replacing plastic bellcrank bushings with precision ball bearings, you'll experience noticeably improved steering precision and faster response times, which directly translates to better handling and control during high-speed runs or technical courses.
• Extended component lifespan — Quality ball bearings reduce friction and wear on steering linkages and suspension components, helping to protect your entire RC car setup and reducing the frequency of maintenance and replacement requirements.
• Genuine Traxxas parts — These are authentic Traxxas OEM (original equipment manufacturer) bearings, meaning they're built to the same exacting standards as your RC vehicle and guaranteed to perform reliably over extended use.
• Pair pack format — Each purchase includes two bearings, providing a convenient matched pair for installation in dual-bearing applications on your RC model.

Technical Performance

These Traxxas ball bearings represent the premium solution for precision RC car steering and suspension upgrades. With dimensions of 4x7x2.5mm, they are engineered to drop directly into steering bellcrank assemblies and other pivot points on compatible Traxxas RC vehicles, eliminating the slop and play that develops in plastic bushings over time. The rubber seals are critical to performance longevity in the UK's variable climate—they provide a protective barrier against road salt, moisture, sand and general dirt ingress that could cause the bearings to seize or perform erratically. The internal rolling ball design ensures smooth, frictionless rotation, enabling your steering servo to work more efficiently and reducing the electrical load on your RC car's receiver and ESC. This efficiency gain can result in slightly improved battery runtime and more responsive handling characteristics. The bright blue colour of the seal is both a quality indicator and a visual confirmation that you've installed genuine Traxxas components. Whether you're running a competitive race setup or a casual basher, upgrading to quality ball bearings from worn plastic bushings will be immediately noticeable in how your RC car responds to steering inputs.

Frequently Asked Questions

• What is the difference between ball bearings and plastic bushings in RC cars? — Plastic bushings are solid components that can wear, crack and develop play over time, causing sluggish and imprecise steering. Ball bearings, by contrast, use rolling balls to eliminate friction and wear, maintaining smooth, responsive operation indefinitely. The upgrade from bushings to quality bearings is one of the most effective performance improvements you can make to an RC car.
• Will these bearings fit my Traxxas RC car? — The 4x7x2.5mm dimensions make these bearings compatible with many Traxxas models, particularly in steering bellcrank applications. However, you should verify the specific bearing size required for your model before purchasing, as different vehicles may use different bearing sizes.
• Are blue rubber sealed bearings waterproof? — The rubber seals provide excellent protection against water, dirt and debris ingress, making these bearings suitable for wet UK weather conditions and muddy terrain. However, they are not fully sealed and are not designed for continuous water submersion.
• How long will these ball bearings last? — With proper maintenance and the protective benefit of the rubber seals, quality Traxxas ball bearings will typically outlast multiple sets of plastic bushings. The sealed design means they require minimal maintenance beyond occasional inspection, and they'll maintain smooth operation through countless hours of RC driving.
• Are these genuine Traxxas parts? — Yes, these are authentic Traxxas OEM ball bearings manufactured to the company's quality standards and identified by the part number TRX5124 and blue seal colour coding.
