6304-2Z Single Row Deep Groove Ball Bearing 20x52x15mm Double Metal Shields Low Noise For Motors Pumps Power Tools

6304-2Z is a widely used deep groove series single row ball bearing fitted with double-sided metal dust shields, standard overall dimension 20×52×15 mm. It is precision processed from wear-resistant GCr15 bearing steel and equipped with stamped steel cage for flexible steel ball rolling.

The 2Z metal shield structure effectively blocks dust and fine impurities to protect internal rolling components. Classic deep groove raceway can bear radial loads as well as bidirectional light axial loads simultaneously. With low friction coefficient, quiet operation and excellent high-speed performance, this bearing is extensively applied to medium-load rotating machinery under dry and dusty working conditions.
