Technical Performance
These ball bearings represent the kind of precision engineering ARRMA is recognised for across the RC hobby. With an inner diameter of 12mm and an outer diameter of 18mm, combined with a 4mm thickness, these bearings are sized to fit the suspension and drivetrain components of numerous ARRMA RC models. The 2RS designation (Double Rubber Shield) is particularly important for UK RC enthusiasts, as it ensures your bearings maintain performance even when driving in typical British weather conditions. The rubber shields work by creating a barrier against moisture, dirt and dust whilst retaining the bearing grease, which is essential for smooth rotation and longevity. The premium ball-raced construction provides consistently low friction across the full range of operating speeds, from gentle control manoeuvres to maximum speed runs. Whether you're driving a brushless monster truck, a brushless short course truck, a brushless buggy or any other ARRMA RTR model, these bearings will integrate seamlessly into your vehicle's suspension and drivetrain systems, maintaining the responsive handling and smooth performance you expect from your radio-controlled vehicle.
