Key Features
- Sealed design — The rubber seals keep dirt, water and debris out of the bearing races, extending bearing life and maintaining smooth operation in wet, muddy or dusty conditions common in UK off-road RC racing.
- Stainless steel construction — The bearing balls are manufactured from high-grade stainless steel, which resists corrosion and provides superior durability compared to standard steel bearings, particularly important for UK users racing in wet weather.
- Pre-greased inner balls — The bearings arrive pre-greased and ready to install, eliminating the need for additional lubrication and ensuring immediate operation without assembly delay.
- Pair of two bearings — You receive two complete sealed ball bearings in this pack, allowing you to replace both sides of an axle or suspension component, or maintain spare parts for quick maintenance between races.
- OEM Losi component — These are genuine factory Losi parts, ensuring they meet exact specifications for TLR 22 and TLR 22X-4 buggy models and deliver the performance Losi engineers designed into these race-winning platforms.
Technical Performance
The LOS Sealed Ball Bearings are engineered to exacting tolerances with 10mm inner bore diameter and 15mm outer diameter, making them the precise size specified for critical drivetrain and suspension locations on TLR racing buggies. Stainless steel ball construction provides superior corrosion resistance and load-carrying capacity compared to standard steel alternatives, which is essential for maintaining tight tolerances in high-precision RC suspension systems. The rubber seals on both sides of each bearing create a barrier against contamination whilst still allowing the bearing to rotate freely under the loads imposed by 1/10 scale off-road RC racing. The pre-greased condition means these bearings are ready to install immediately without additional preparation, saving time during maintenance sessions. In competitive environments where even microscopic play can affect handling and consistency, sealed bearings like these maintain their precision over extended use, making them a critical component for serious RC enthusiasts and competitors across the UK who demand reliability from their equipment.

Frequently Asked Questions
- What size are the LOS Sealed Ball Bearings Z-LOSA6943? — These bearings measure 10mm inner diameter by 15mm outer diameter, making them the correct size for suspension and drivetrain locations on TLR 22 5.0 and TLR 22X-4 buggies. They are designation 22/22-4 in the bearing specification system.
- Which Losi RC cars use these 10x15mm sealed bearings? — These bearings are compatible with the TLR 22 5.0 DC ELITE Race Kit (1/10 2WD Dirt/Clay) and the TLR 1/10 22X-4 ELITE 4WD Buggy Race Kit. Check your specific model documentation to confirm bearing locations and quantity needed for a complete rebuild.
- What is the difference between sealed and shielded bearings for RC cars? — Sealed bearings feature rubber seals that completely close off the bearing races, providing maximum protection against water, mud and dirt ingress, making them ideal for wet UK racing conditions. Shielded bearings use contact seals that allow some air circulation but offer less protection. Sealed bearings are superior for durability in harsh conditions but may have slightly higher rolling resistance.
- Are these bearings pre-greased and ready to use? — Yes, these Losi sealed ball bearings arrive pre-greased with the inner balls already coated in lubricant, ready for immediate installation without requiring additional lubrication during assembly.
- Why should I buy genuine Losi bearings instead of cheaper alternatives? — Genuine Losi OEM bearings are manufactured to exact tolerances designed by Losi engineers to work perfectly with TLR suspension geometry and drivetrain components. Counterfeit or generic bearings may have dimensional variations that introduce play, compromise handling precision, and reduce vehicle lifespan. For competitive RC racing where consistency is critical, genuine parts are a worthwhile investment.
- How many bearings do I need to fully service my TLR buggy? — The number of bearings required depends on your specific TLR model and which components you are servicing. Consult your vehicle manual or contact our RC Model Shop team to determine the exact quantity needed for a complete bearing replacement on your model.
