Main Description

The 608 ZZ W6 EZO 8x22x6 is a single-row deep groove ball bearing featuring metal shields (ZZ) on both sides and a nonstandard width of 6 mm (the “W6” variant). Manufactured by EZO, this miniature bearing is engineered for scenarios demanding compactness, low friction, and moderate protection against contaminants. According to EZO’s catalog, the dimensions are 8 mm inner diameter x 22 mm outer diameter x 6 mm width.

Because it deviates by 1 mm in width from the common 7 mm thickness of a typical 608 ZZ, the W6 version is ideal in assemblies where space is limited in the radial direction yet standard mounting housings are used.

Applications & Typical Uses

This bearing suits many miniature mechanical, electromechanical, and automation applications where reliability, compact size, and moderate shielding are required:

• Small electric and brushless motors

• Precision instruments, robotics joints, micro gearboxes

• Fans, blowers, and micro pump systems

• 3D printers, automation heads, CNC axes

• Consumer electronics, handheld devices, micro drives

• Rollers, pulleys, and small linear motion systems

The 608 series is heavily used across hobbyist, industrial, and repair sectors. The variant 608 ZZ W6 EZO is often cross-referenced when designers need a thinner profile than standard 608 ZZ.

Key Advantages & Design Features

• Metal shields (ZZ): non-contact shields that protect bearings from dust and fine debris without excessive drag

• Reduced width (6 mm vs. 7 mm): allows tighter axial or radial packaging in assemblies where size is constrained

• Low friction & smooth rotation: deep groove geometry keeps motion efficient, minimizing vibration and noise

• Pre-lubricated & maintenance-friendly: factory grease plus shielding tends to retain lubricant and reduce maintenance intervals

• Compatibility & interchangeability: since bore and outer diameters match standard 608 dimensions, many components and housings are compatible

• Reliable brand backing: EZO is known for precise miniature bearings and good quality control

Simmering lists this variant as “High-performance bearing designed to handle both radial and axial loads efficiently” and notes limited stock, indicating that it is a specialty item.
