MR105 5x10x4mm Miniature Deep Groove Ball Bearing for RC Cars Drones Robotics

MR105 Miniature Deep Groove Ball Bearing – Precision Where Space Is Limited

Miniature ball bearings belong to one of the most widely used bearing categories across numerous industries. Their small size, simple construction, and reliable performance make them indispensable for applications where space is constrained and precision is paramount.With its ability to handle both radial loads and light axial loads in both directions, the MR105 provides a versatile solution for countless small machinery applications.

主要特点:

• High Precision
  The MR105 is manufactured from high-carbon chrome steel, offering excellent strength, hardness, wear resistance, and rolling contact fatigue resistance. Through-hardened rings and precision-ground balls ensure consistent performance, 低摩擦, and long service life.

• 多功能负载处理
  The deep groove raceway geometry enables the MR105 to support both radial loads and light axial loads in both directions.This versatility reduces the number of bearings required in an assembly and simplifies mechanical design. The precisely machined raceways also ensure smooth ball guidance and efficient load distribution, reducing vibration and extending operational life.

• 高速
  The MR105 is designed for high-speed operation.This high-speed performance makes the MR105 suitable for small electric motors, high-speed spindles, and other applications where rotational velocity is a critical parameter.
• 低摩擦, 低噪音, 低振动
  Precision grinding of raceways and balls results in a very low coefficient of friction, reducing power consumption and heat generation, and significantly lowering audible noise. The low noise and low vibration characteristics make the MR105 well-suited for consumer electronics, 医疗器械, and office equipment where quiet operation enhances user experience.
• Lightweight and Space-Saving
  With a mass of only approximately 1–1.29 grams and a compact 5 mm bore / 10 mm OD envelope, the MR105 adds negligible weight to assemblies.
