V623ZZ Bearing 3x12x4mm V Groove Double Shielded Ball Bearing

V623ZZ Bearing 3x12x4mm V Groove Double Shielded Ball Bearing

The V623ZZ V Groove bearing (3x12x4mm) is a high-precision miniature guide wheel bearing designed for smooth linear motion and reliable performance in compact mechanical systems.

• Featuring a V-shaped outer race and double metal shields (ZZ), this bearing ensures reduced friction, protection from dust, and long service life.
• The V623ZZ bearing is a compact V groove  bearing built for smooth tracking and guiding on rails, edges, and linear motion paths.
• With a precision 3x12x4mm bearing size and double shielded ball bearing (ZZ) design, it helps reduce contamination from dust and debris while maintaining consistent rolling performance.
• This V groove bearing 3x12x4mm is ideal for light-load guidance applications in motion assemblies and small mechanisms.
