MR63ZZ 3x6x2.5mm 铬钢微型深沟球轴承

产品概述

When your mechanical design demands reliable rotation in a space no larger than a grain of rice, the MR63ZZ miniature deep groove ball bearing delivers uncompromising performance. With exacting metric dimensions of 3 毫米孔径, 6 毫米外径, 和 2.5 毫米宽度, this bearing belongs to the MR series of miniature ball bearings, engineered specifically for applications where space is severely limited but smooth, high-speed rotation remains critical.

主要特点:

• Ultra-Compact Space
  The MR63ZZ is one of the smallest deep groove ball bearings available. Its miniature dimensions enable the miniaturization of 3D printers, 无人机, 遥控模型, 和精密仪器而不牺牲性能.

• 高速能力
  Despite its tiny size, the MR63ZZ achieves a grease-lubricated limiting speed of 69,000–71,000 RPM. This makes it ideal for micro motors, high-speed spindles, 以及其他旋转速度至关重要的应用.

• Effective Contamination Protection
  The double metal shields provide effective protection against dust and debris while maintaining the low friction required for high-speed operation. The shields also retain the factory-applied grease, 减少维护需求.
• 低噪音、低振动
  Precision grinding of raceways and quality ball manufacture result in smooth, quiet operation with minimal vibration. The low friction and quiet operation make the MR63ZZ ideal for noise-sensitive environments like consumer electronics.
