10 Pcs 6902RS Ball Bearings 15x28x7mm - ABEC 3 Precision Blue Rubber Sealed For RC Cars And Bike Hubs

RC enthusiasts and mechanics, this 10-pack of 6902RS ball bearings is your ticket to smoother running equipment and vehicles! These precision bearings measure 15x28x7mm with ABEC 3 rated races made from chrome steel (52100/GCr15) for consistent performance and long service life. The blue rubber seals provide maximum protection against dust, dirt, and moisture - exactly what you need for off-road RC cars that see muddy conditions or bike hubs exposed to the elements. Each bearing comes pre-lubricated with quality grease for immediate use right out of the package. These are direct replacements for Losi part number LOSB5976 and work in various applications including RC vehicles, bicycle hubs, skateboards, and other machinery requiring reliable rotational movement. The rubber sealed design means they'll last much longer in dirty environments compared to unsealed bearings that quickly fail when contaminants get inside. Having a 10-pack means you can replace multiple bearings at once or keep spares on hand for future maintenance needs. The precision construction ensures minimal vibration and friction, translating to better performance and efficiency in your applications. Whether you're rebuilding an RC car transmission, upgrading bike hubs, or repairing industrial equipment, these bearings deliver professional-grade performance without the professional price tag. The consistent quality across all ten bearings means you can use them with confidence in critical applications. The blue seals make identification easy when working on multiple projects simultaneously. Perfect for hobbyists who want to upgrade from stock bearings or mechanics needing reliable replacements for worn-out components. The durability and protection features make these ideal for applications where bearing failure would mean costly downtime or repairs.
