MR62, MR62Z, MR62ZZ, MR62RS, MR62-2RS Miniature Deep Groove Ball Bearings 2x6x2.5mm – Ultra-Small Precision Bearings for Micro Motors, Drones, RC Toys & Smart Electronics

Ultra-compact MR62 series miniature deep groove ball bearings in size 2mm (ID) × 6mm (OD) × 2.5mm (W), designed for space-constrained applications requiring smooth, quiet, and low-friction rotation. Ideal for micro motors, tiny drones, RC toys, smart locks, wearable devices, cooling fans, and precision electronic instruments.

Available in multiple sealing configurations to match your operating environment:

MR62: Open type – minimal drag, perfect for clean or controlled settings
MR62Z / MR62ZZ: Single or double metal shields – reduce dust ingress while maintaining low torque
MR62RS / MR62-2RS: Single or double rubber seals – provide superior protection against moisture, dust, 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, mini gearboxes, robotics joints, medical micro-tools, and consumer electronics, the MR62 series balances miniaturization with mechanical robustness.

🔧 Key Specifications:
