GQZ 6004-2Z Deep Groove Ball Bearing 20×42×12mm Double Metal Shields Dustproof Open Inner Structure

6004-2Z is single row deep groove ball bearing equipped with double-sided metal dust shields. It can bear simultaneous radial and moderate bidirectional axial loads, features low friction, stable high-speed rotation and excellent dustproof performance. The metal shield design prevents large particle dust intrusion without full waterproof capacity, widely used in light-load general mechanical equipment running in clean dry environment.
