608 H ZZ EZO 8x22x7 Deep Groove Ball Bearing

Precision 608 H ZZ EZO Bearing for High Speed Industrial Applications

The 608 H ZZ EZO 8x22x7 deep groove ball bearing is a precision single row ball bearing designed for compact high speed applications requiring smooth rotation, low vibration and long operating life. The ZZ metal shields on both sides protect the internal raceways against contamination while maintaining very low rolling resistance, making this model ideal for electric motors, automation systems and precision industrial devices.

The 608 series belongs to one of the most widely used categories of deep groove ball bearings in industrial and technical applications. The EZO version is valued for Japanese manufacturing precision, stable dimensional accuracy and quiet operation under continuous load conditions.

Construction and Design Characteristics

The 608 H ZZ EZO bearing features a compact radial design optimized for high rotational speeds and reduced operating noise. The shielded construction minimizes contamination ingress while allowing efficient operation at elevated RPM.

Main construction features:

• inner diameter: 8 mm
• outer diameter: 22 mm
• width: 7 mm
• double metal shields ZZ
• single row deep groove ball bearing
• high precision steel raceways
• factory lubricated
• low friction operation
• compact lightweight construction

The metal shields significantly reduce dust penetration while maintaining lower rotational resistance compared to contact seal designs. This makes the bearing especially suitable for high speed mechanisms.
