These ZZ-sealed deep groove ball bearings are designed for applications where moisture, washdown, or chemical exposure would shorten the service life of conventional bearings — making them a reliable choice for food-processing equipment, marine hardware, medical devices, and outdoor power tools.\u003c\/p\u003e\n\u003cp\u003eEach bearing is manufactured from stainless steel throughout — inner ring, outer ring, balls, and cage — and fitted with double-sided metal shields (ZZ) to retain grease and exclude particulate contamination.

For combined radial and moderate axial loads (such as in electric motors or fans), these bearings perform well within their rated capacity.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eDo I need to add grease before installation?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eNo. These bearings are factory-greased and sealed with ZZ shields, so they are ready to install without additional lubrication. Avoid removing the shields or washing out the factory grease. If the bearing will operate at elevated temperatures or in a demanding duty cycle, consult the grease specification for your operating conditions and re-grease through a fitting if your housing design allows it.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat is the difference between the 6800, 6900, 6000, 6200, and 6300 series?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eThese designations refer to different dimensional series with varying relationships between bore diameter and outer diameter.
