MR82, MR82Z, MR82ZZ, MR82RS, MR82-2RS Miniature Deep Groove Ball Bearings 2.5x8x3mm – Precision Micro Bearings for Small Motors, Drones, RC Models & Smart Electronics

Ultra-compact MR82 series miniature deep groove ball bearings in size 2.5mm (ID) × 8mm (OD) × 3mm (W), engineered for space-constrained applications that demand smooth, quiet, and low-friction rotation. Ideal for micro motors, mini drones, RC toys, smart locks, wearable devices, cooling fans, and precision electronic instruments.

Available in multiple sealing configurations to suit your operating environment:

MR82: Open type – minimal rotational resistance, perfect for clean or controlled settings
MR82Z / MR82ZZ: Single or double metal shields – reduce dust ingress while retaining factory grease
MR82RS / MR82-2RS: Single or double rubber seals – provide superior protection against moisture, fine particles, and contaminants

Manufactured from high-grade stainless steel (AISI 440C) as standard—offering excellent corrosion resistance—or chrome steel upon request. These micro bearings deliver exceptional 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 MR82 series balances miniaturization with mechanical durability.

🔧 Key Specifications:
