MR106The MR106 bearing is suitable for precision instruments, micro motors, medical devices, optical equipment, robotic joints, precision transmission systems, small household appliances, electronic device cooling fans, model making, and automated control systemsindustries with strict space constraints and requirements for high precision and low-noise operation.
Product structure:
The MR106 is a miniature deep groove ball bearing with standard dimensions of 6mm inner diameter, 10mm outer diameter, and 3mm width. It features an open structure, typically composed of inner and outer rings, steel balls, and a cage. The rings are made of stainless steel (e.g., AISI 440C or AISI 304), with cage options including nylon, stainless steel, or brass. Its deep groove design enables it to handle radial loads and limited bidirectional axial loads, offering a compact structure suitable for miniaturized assembly.
Key performance features:
The MR106 bearing offers high-speed capability (up to tens of thousands of RPM under grease lubrication), low starting torque, and minimal operational friction for efficient power transmission. Its stainless steel construction provides excellent rust and corrosion resistance, making it suitable for damp or clean environments. With precision grades up to ABEC-3/5/7 or higher, it ensures smooth operation with minimal vibration and noise. The nylon cage version further reduces noise and lubrication requirements. Easy to maintain and long-lasting, it is an ideal choice for miniature precision applications.
Main application scenarios:
The MR106 bearing is commonly used in micro DC motors (e.g., drone gimbal motors, small fan motors), precision instruments (e.g., optical encoders, microscope stages), medical devices (e.g., dental handpieces, micro-infusion pumps), office automation equipment (e.g., printer and scanner drive shafts), precision models (e.g., RC model car transmission systems), and various small rotating devices (e.g., instrument pointer shafts, precision turntables). It provides reliable rotational support for miniaturized and lightweight equipment.
Technical Specifications and Requirements:
The MR106 bearing must comply with the ISO 12297-1:2012 international standard for miniature bearings or the Chinese standard GB/T 20056-2006 for miniature ball bearings. Its basic dynamic load rating (C) is approximately 0.38 kN, and the basic static load rating (C0) is about 0.16 kN. The speed limit varies with lubrication: it is recommended not to exceed 30,000 RPM under grease lubrication, with higher speeds possible under oil lubrication. The operating temperature range is typically -30°C to +120°C (standard stainless steel version). Proper tolerance fits (usually shaft h5, housing H6) are essential during installation to avoid excessive interference or clearance. The operating environment should be clean to prevent dust ingress; for high-speed or special conditions, regular replenishment of high-speed grease (e.g., NLGI Grade 2) is required. Non-stainless steel versions require rust prevention measures.
