Overview
The Losi 6 x 10 x 3mm Ball Bearing, Rubber Sealed (4) Z-LOS-2300 is an essential replacement and upgrade component for RC enthusiasts maintaining and tuning their Losi models. These precision ball bearings are engineered to deliver smooth, reliable performance in demanding RC applications. Whether you're a seasoned RC competitor fine-tuning your setup for maximum performance, or a dedicated hobbyist looking to maintain your RC car in top condition, high-quality bearings are fundamental to achieving consistent handling and longevity. Losi is a recognised manufacturer of premium RC components, and these rubber-sealed bearings represent the quality you can expect from the brand.
Rubber-sealed ball bearings offer significant advantages over unsealed alternatives, particularly for RC models used in the UK where moisture, dust and debris are common environmental challenges. The rubber seal helps protect the bearing's internal surfaces from contamination whilst maintaining smooth rotation, which translates to better overall performance and extended bearing lifespan. These bearings are compact yet robust, making them suitable for precision applications where reliability cannot be compromised. The 6 x 10 x 3mm dimensions are specifically engineered for Losi models, ensuring a perfect fit and optimal performance in your RC vehicle.
RC Model Shop stocks genuine Losi components and replacement parts for RC enthusiasts across the UK. Whether you need to replace worn bearings on your existing RC model or you're building a custom setup, sourcing OEM-specification bearings like these ensures your RC vehicle performs exactly as the manufacturer intended. This four-pack provides enough bearings for multiple applications or to keep spares on hand for maintenance.
Key Features
- Rubber Sealed Design — The rubber seals on these bearings protect the internal ball races and rolling elements from dirt, moisture and dust that can cause friction and wear, which is especially important for RC models used outdoors in the UK climate where conditions are often damp or dusty.
- Precision Ball Bearing Construction — These are true ball bearings rather than bushings, meaning they use hardened steel balls rolling on precision-ground races to deliver extremely low friction and smooth, consistent rotation that translates directly to better handling and acceleration in your RC car.
- Six x Ten x Three Millimetre Dimensions — The specific 6 x 10 x 3mm size is engineered to fit perfectly in Losi 1/4 Promoto-SM models and other compatible Losi RC vehicles, ensuring the correct fit and preventing potential performance issues from mismatched components.
- Pack of Four Bearings — This four-pack provides multiple bearings in a single purchase, allowing you to replace worn bearings in multiple locations on your RC model or keep spares readily available for future maintenance and repairs.
- Genuine Losi OEM Component — As an original Losi part, these bearings are manufactured to exact specifications and tolerances, guaranteeing compatibility and performance in all listed compatible models without any fitment issues.
Technical Performance
These Losi ball bearings represent precision engineering designed specifically for high-performance RC applications. The 6 x 10 x 3mm dimensions indicate a bearing with a 6mm inner diameter bore, a 10mm outer diameter, and a 3mm width, creating a compact yet robust component capable of handling the dynamic loads encountered in RC vehicle operation. The rubber seal design is critical to long-term reliability: rather than being exposed, the bearing races and rolling elements are protected by a flexible rubber shield that prevents contamination ingress whilst still allowing smooth rotation. This design is particularly valuable for RC models used in varied outdoor conditions, as it maintains performance even when exposed to moisture, dirt and debris common in UK environments. The hardened steel construction ensures durability under repeated stress cycles, whilst the precision manufacturing guarantees consistent performance across the bearing pack. When properly installed in compatible Losi models, these bearings support smooth suspension movement, precise steering response and reliable drivetrain operation.

Frequently Asked Questions
- What Losi RC models use these 6 x 10 x 3mm ball bearings? — These bearings are compatible with the Losi 1/4 Promoto-SM FXR Supermoto Motorcycle RTR (both the standard version with battery and charger included and the basic version), making them essential spares for owners of these models who want to maintain performance and reliability.
- Why should I replace my RC bearings with sealed versions? — Sealed bearings offer superior protection against moisture and contamination compared to open bearings, which is vital for RC models used in the UK where outdoor conditions are often damp or dusty; the seal maintains smooth performance whilst protecting the internal rolling elements from wear-causing debris.
- How often should I replace bearings in my RC model? — Bearing lifespan depends on usage intensity and environmental conditions; if you notice increased friction, grinding sounds or sluggish rotation, it's time to replace the bearings; routine maintenance and using sealed bearings like these significantly extends the intervals between replacements.
- Are these genuine Losi parts? — Yes, these are genuine original Losi components manufactured to OEM specifications, ensuring perfect compatibility and performance in all listed Losi models without any fitment or quality concerns.
- What is the difference between sealed and unsealed bearings for RC models? — Sealed bearings feature rubber or metal shields that prevent dirt and moisture from entering the bearing races, maintaining smooth operation longer in dusty or damp conditions; unsealed bearings offer slightly lower friction but require more frequent maintenance and are prone to premature wear in outdoor environments.
