Overview
The ARRMA Bearing 15x21x4mm (2) Z-AR610018 is an essential replacement component for RC enthusiasts across the UK who demand smooth, reliable performance from their ARRMA vehicles. These high-quality ball bearings are precision-engineered to deliver consistent running across all types of terrain, whether you're bashing in the garden, racing on a track, or tackling challenging off-road courses. If you own an ARRMA RC car UK model and want to maintain peak performance, these replacement bearings are a must-have addition to your spares collection.
Ball bearings are the unsung heroes of RC performance. They reduce friction between moving parts, allowing your RC car to operate with minimal resistance and maximum efficiency. Over time, standard bearings wear out through use and exposure to dust, dirt and moisture on the track or field. By upgrading or replacing your bearings with genuine ARRMA components, you ensure your vehicle maintains the super-smooth operation and fast response it had when new. Whether you're a seasoned RC enthusiast or a weekend basher enjoying the thrills of remote control driving, these bearings will keep your ARRMA running at its best.
This pack contains two ball bearings, which means you have a complete pair for your ARRMA RC car. The 15x21x4mm size is specifically engineered for compatibility with select ARRMA 1/10 scale models, ensuring precise diameter fitting that maintains the exact tolerances your vehicle requires. With genuine ARRMA bearings, you're investing in quality, reliability and the longevity of your RC investment.

Technical Performance
These ball bearings represent the engineering excellence ARRMA brings to every component. The 15x21x4mm specification has been carefully selected for compatibility with specific ARRMA 1/10 scale models, ensuring that when you install them, they integrate seamlessly with your existing drivetrain and suspension systems. Ball bearings work by distributing load across multiple rolling spheres, which dramatically reduces the friction that would otherwise slow your vehicle down and waste battery power. This means better acceleration, higher top speeds and more efficient power delivery from your brushless motor or brushed motor system. The super-smooth ball-race design means that rotational movement happens with minimal resistance, translating directly to improved performance whether you're operating your RC car on tarmac, grass, gravel or purpose-built RC tracks. Built to the same high standards as genuine ARRMA replacement parts, these bearings maintain their smooth operation even after repeated use and exposure to the outdoor environments where most RC cars UK are driven. The precise manufacturing tolerances ensure zero play when installed, which is critical for maintaining the handling precision and responsiveness that serious RC enthusiasts demand from their vehicles.

Frequently Asked Questions
- Which ARRMA models are these bearings compatible with? — These 15x21x4mm bearings are compatible with the ARRMA 1/10 Kraton 4X4 4S V2 BLX Speed Monster Truck RTR and ARRMA 1/10 Kraton 4X4 4S V2 BLX Speed Monster Truck RTR in Green.

- Why should I replace my bearings? — Ball bearings wear over time, especially with regular use and exposure to outdoor conditions. Worn bearings increase friction, reduce efficiency, lower top speed and can even cause handling problems. Replacing them with fresh ARRMA bearings restores your vehicle to like-new performance and ensures smooth, responsive operation.

- Is this suitable for beginners? — Bearing replacement is a straightforward maintenance task that most RC enthusiasts can handle with basic tools and a little patience. If you're new to RC maintenance, our team at RC Model Shop can provide guidance and support to help you keep your vehicle in top condition.
- How often should bearings be replaced? — This depends on how heavily you use your ARRMA vehicle and the conditions in which you operate it. Bearings exposed to wet, muddy or sandy environments may require more frequent replacement than those used primarily on dry tracks, but regular inspection for smoothness and responsiveness will tell you when replacement is needed.
