SMR85-2RS Ceramic Ball Bearing - Sealed - 5x8x2.5mm

SMR85-2RS Ceramic Stainless Steel Ball Bearing 
5mm x 8mm x 2.5mm - Hybrid Ceramic, Rubber Sealed

This ultra-compact SMR85-2RS bearing is engineered for high-speed, low-friction performance in tight spaces. Ideal for micro motors, RC models, drones, and other precision devices, it features hybrid ceramic construction - stainless steel races and silicon nitride (Si₃N₄) ceramic balls - for increased speed, longevity, and reduced rolling resistance.

💡 What makes hybrid ceramic bearings better than all-steel bearings?
Hybrid ceramic bearings run cooler, resist wear better, and tolerate higher speeds because ceramic balls are smoother, lighter, and less heat-conductive than steel - making them perfect for precision and high-performance environments.
