618/7 2RS EZO 7x14x5 Deep Groove Ball Bearing

Miniature 618/7 2RS EZO Bearing for Compact Rotating Systems

The 618/7 2RS EZO 7x14x5 deep groove ball bearing is designed for compact mechanical systems requiring high precision, low rolling resistance and stable high speed operation. Equipped with double rubber seals 2RS, the bearing effectively protects internal raceways against dust, moisture and grease leakage, helping extend operational life and maintain reliable rotational performance.

The 618 series belongs to the family of thin section deep groove ball bearings commonly used in electronic devices, precision automation systems, lightweight drives and miniature mechanical assemblies. EZO Japan bearings are recognized for excellent manufacturing accuracy, low vibration levels and smooth operation at elevated rotational speeds.

Bearing Construction and Design

The 618/7 2RS EZO bearing features a single row thin section deep groove ball bearing structure designed for smooth rotation and balanced load distribution during continuous operation.

Main construction features:

• inner diameter: 7 mm
• outer diameter: 14 mm
• width: 5 mm
• double rubber seals 2RS
• factory lubricated
