MR 83 ZZ SMB Miniature Deep Groove Ball Bearing 3x8x3 mm

MR 83 ZZ SMB Miniature Deep Groove Ball Bearing 3x8x3 mm

MR 83 ZZ SMB is a miniature deep groove ball bearing designed for precision applications requiring compact dimensions, low friction and stable high-speed performance.

Industrial applications

The MR 83 ZZ SMB miniature ball bearing is widely used in industries where space is limited and precision is critical. Its compact 3x8x3 mm size makes it suitable for:

• electronic devices and micro-mechanical systems
• printers, scanners and office equipment
• RC models and small drive systems
• miniature electric motors and fans
• measuring and medical equipment

This type of miniature bearing is essential in applications where standard deep groove ball bearings cannot be installed due to size constraints.

Construction and design

The MR 83 ZZ SMB deep groove ball bearing features a single-row design optimized for smooth rotation and consistent performance.

It is equipped with ZZ metal shields on both sides, which protect against dust and small particles while retaining lubrication inside the bearing. This design ensures extended service life with minimal maintenance requirements.

Precision-ground raceways and high-quality steel balls provide low friction, reduced vibration and reliable operation even at high rotational speeds.
