MR83, MR83Z, MR83ZZ, MR83RS, MR83-2RS Miniature Deep Groove Ball Bearings 3x8x3mm – Precision Micro Bearings for Small Motors, Drones, RC Models & Smart Electronics

The MR83 series miniature deep groove ball bearings feature compact dimensions of 3mm (ID) × 8mm (OD) × 3mm (W), delivering smooth, quiet, and low-friction rotation in space-constrained applications. Ideal for micro 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:

MR83: Open type – minimal rotational resistance, perfect for clean or controlled settings
MR83Z / MR83ZZ: Single or double metal shields – reduce dust ingress while retaining factory grease
MR83RS / MR83-2RS: Single or double rubber seals – provide superior protection against moisture, dust, and fine contaminants

Manufactured from high-grade 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 high speeds.

Commonly used in brushless DC (BLDC) micro motors, FPV drone gimbals, tiny gearboxes, robotics joints, medical micro-tools, and consumer electronics, the MR83 series balances miniaturization with mechanical durability.

🔧 Key Specifications:
