Deep Groove Ball Bearing 6304-2RS – Bore 20 mm
6304-2RS is a high-quality single-row deep groove ball bearing equipped with double-sided rubber contact seals (designated as 2RS). Precision engineering and factory pre-lubrication ensure maintenance-free operation and an extended service life.
Deep groove ball bearings are the most versatile bearing type, designed to accommodate radial and axial loads in both directions, even at high rotational speeds. The rubber seals effectively protect the internal rolling elements against dust, contamination, and moisture.
Applications
- electric motors and generators,
- power tools and home appliances,
- water pumps and ventilation systems,
- agricultural and construction machinery,
- mechanical gearboxes and conveyor rollers.
