If you need steady, low-friction components, the Factory Pro FP-B-SB0510 steel ball bearings measure 5x10x4mm and are supplied as ten pieces. They provide predictable rotation for common RC maintenance tasks.
Factory Pro produces these steel bearings with focus on dimensional accuracy and durability. That makes them suitable for regular running and routine race prep where consistent behaviour matters.
The 5x10x4mm dimension fits many wheel bearings, gearbox mounts and small rotating linkages on typical 1/10 scale kits. Carrying a set of FP-B-SB0510 bearings helps reduce service time between sessions.
