6004-2Z Single Row Deep Groove Ball Bearing 20x42x12mm Double Metal Shields Low Noise For Motors Fans Power Tools

6004-2Z is a single row deep groove ball bearing with double-sided steel shields. It features metric dimensions 20×42×12 mm, crafted from high-strength GCr15 bearing steel with stamped steel retainer. The 2Z metal shield structure effectively blocks dust and solid particles, delivering reliable dust-proof performance for ordinary working environments.

This bearing can bear both radial load and bidirectional light axial load simultaneously, boasts low friction coefficient, stable high-speed operation and low noise performance. With standard normal internal clearance, it adapts to most general transmission scenarios.

Widely applied in small motors, cooling fans, power tools, textile machinery, agricultural equipment, household appliances, pumps, wheel rollers and various general industrial rotating machinery components.
