For RC crawler enthusiasts in the UK who demand reliability and performance, this bearing set is an investment that pays dividends in every session. The black rubber sealed construction offers a step above standard blue-seal bearings, providing an even tighter seal that protects against dirt, moisture and debris—perfect for outdoor RC car use in variable British weather conditions.

This complete bearing set includes everything you need to fully equip both front and rear tracks of your TRX-4 Traxx, making it the perfect choice whether you're upgrading a new ready to run RC model or refreshing a well-used crawler. Installation is straightforward for experienced builders, and the performance improvement is immediately noticeable.

Key Features

• Black Rubber Sealed Design — The black rubber seals on these bearings provide superior protection compared to standard blue-seal alternatives, creating an even tighter seal that keeps dirt, dust, and moisture out of the bearing races. This is especially valuable for RC crawler operators in the UK who frequently run in muddy, wet, or sandy conditions, as the enhanced sealing means less maintenance and longer bearing life even in dirty environments.
• Stainless Steel Construction — These bearings are manufactured from stainless steel, which offers exceptional corrosion resistance and durability. Stainless steel maintains its structural integrity even when exposed to moisture and salt, making it ideal for outdoor RC car use and ensuring your bearings won't degrade prematurely or develop rust.
• Reduced Friction and Rolling Resistance — Ball bearings inherently provide dramatically lower friction than traditional oilite bushings, which means your TRX-4 Traxx will roll more freely, accelerate faster, and maintain speed longer on a single battery charge. This performance advantage is cumulative across all the joints and pivot points in your vehicle, resulting in noticeable improvements in overall handling and efficiency.
• Low Maintenance Operation — Unlike bushings which require regular maintenance and lubrication, ball bearings are engineered to run smoothly with minimal intervention. Once installed and properly lubricated, they deliver consistent performance throughout extended use sessions with virtually no degradation.
• Extended Running Times — The efficiency gains from switching to ball bearings mean your TRX-4 Traxx will travel further and perform longer on the same battery capacity. For competitive RC enthusiasts and weekend bashers alike, this translates to more driving enjoyment per charge cycle.
• Aircraft-Quality Steel Construction — These bearings are manufactured to aircraft-quality standards, ensuring precision engineering and tight tolerances that guarantee smooth rotation and reliable performance under the stresses of RC crawler operation.
• Complete Track Bearing Solution — This set contains all the bearings needed to fully equip both front and rear tracks of your TRX-4 Traxx, eliminating the need to source parts from multiple suppliers and ensuring compatibility and consistency across your entire vehicle.
• Pre-Lubricated for Immediate Performance — The bearings arrive pre-lubricated to factory specifications, meaning you can install them and enjoy immediate performance improvements without additional preparation or break-in periods.
