MR95, MR95Z, MR95ZZ, MR95RS, MR95-2RS Miniature Deep Groove Ball Bearings 5x9x3mm – Precision Micro Bearings for Small Motors, Drones, RC Models & Smart Electronics

The MR95 series miniature deep groove ball bearings feature compact dimensions of 5mm (ID) × 9mm (OD) × 3mm (W), delivering smooth, quiet, and low-friction rotation in space-limited applications. Ideal for small motors, mini drones, RC cars/airplanes, smart locks, wearable tech, cooling fans, and precision electronic instruments.

Available in multiple sealing configurations to suit your operating environment:

MR95: Open type – minimal rotational resistance, perfect for clean or controlled settings
MR95Z / MR95ZZ: Single or double metal shields – reduce dust ingress while retaining factory grease
MR95RS / MR95-2RS: Single or double rubber seals – provide superior protection against moisture, dust, and fine contaminants

Manufactured from high-quality stainless steel (AISI 440C) as standard—offering excellent corrosion resistance—or chrome steel upon request. These micro bearings ensure high rotational accuracy, low noise, and reliable performance even at elevated speeds.

Commonly used in brushless DC (BLDC) motors, FPV drone gimbals, tiny gearboxes, robotics joints, medical micro-tools, and consumer electronics, the MR95 series strikes an ideal balance between miniaturization and mechanical robustness.
