6217 Open Deep Groove Ball Bearing | High-Speed Unsealed Metric Design | 85×150×28 mm

The 623-ZZ is an ultra-compact, high-precision miniature ball bearing engineered for micro-mechanical systems where space is strictly limited but high-speed performance is essential. Outfitted with twin pressed steel shields (ZZ) to safely retain high-grade lubricant and deflect micro-debris, this bearing delivers exceptionally low rotational resistance. With a tiny 3mm bore, a 10mm outer diameter, and a 4mm width, the 623-ZZ is the definitive solution for 3D printer extruders, micro-scale drone motors, and delicate instrumentation requiring frictionless, ultra-smooth movement.

The 6206-ZZ is a highly versatile, single-row deep groove ball bearing from the standard 6200 light series, featuring dual pressed steel shields. Designed with a 30 mm bore, a 62 mm outer diameter, and a 16 mm width, this model is celebrated as one of the most reliable "workhorse" bearings in the industrial sector. The non-contact metal shields are engineered to retain the factory-filled grease while effectively deflecting larger particulate matter and debris. Because these shields do not physically rub against the inner ring, the 6206-ZZ operates with remarkably low friction, making it the optimal choice for high-speed electric motors, pumps, and automated machinery where both moderate protection and maximum rotational efficiency are required.

The 6220 is a robust, single-row deep groove ball bearing engineered for heavy-duty industrial environments where maximum load capacity and unrestricted lubrication flow are required. Unlike shielded or sealed variants, this "Open" configuration features no closures on either side. This unsealed design allows the bearing to be fully submerged in oil baths or integrated into circulating lubrication systems, ensuring rapid heat dissipation and zero friction from contact seals. With standardized metric dimensions—a 100 mm bore, 180 mm outer diameter, and 34 mm width—the 6220 delivers exceptional radial support and moderate axial load handling for large-scale machinery and industrial powertrains.

Engineered for demanding industrial environments, the 6219-ZZ is a robust, single-row deep groove ball bearing built to handle substantial radial loads and moderate axial forces. Unlike miniature high-speed counterparts, this heavy-duty model utilizes dual pressed-steel shields (ZZ) designed to lock in high-quality factory grease while providing a formidable barrier against industrial debris, metal shavings, and heavy dust. With standardized metric dimensions—a 95 mm bore, 170 mm outer diameter, and 32 mm width—the 6219-ZZ delivers unwavering stability and long-lasting performance for large-scale machinery, industrial power transmission, and heavy automotive applications.

The 6219 is a high-capacity, single-row open deep groove ball bearing engineered for rugged industrial environments where maximum radial load support and external lubrication flow are essential. Unlike shielded or sealed variants, this open-type bearing exposes the inner raceways and rolling elements, making it the perfect solution for machinery utilizing oil-bath or continuous circulating lubrication systems. Built to precise metric dimensions—a 95 mm bore, 170 mm outer diameter, and 32 mm width—the 6219 delivers uncompromising structural integrity and operational stability for large-scale equipment, heavy gearboxes, and industrial motors.

The 6218 is a premium-grade, single-row deep groove ball bearing specifically manufactured for demanding industrial applications requiring seamless lubricant access and formidable load management. As an "Open" specification bearing, it does not utilize side shields or rubber seals. This fully unsealed architecture allows the internal rolling elements to be completely bathed in external lubrication systems, promoting rapid thermal dissipation and eliminating any drag associated with contact seals. Precisely engineered to standard metric dimensions—a 90 mm bore, 160 mm outer diameter, and 30 mm width—the 6218 serves as a highly reliable mechanical foundation for large-scale rotary equipment and heavy powertrains.

Engineered for enclosed mechanical environments where external lubrication is continuously supplied, the 6217 Open is a premium single-row deep groove ball bearing designed without shields or seals. This "open" architecture allows for the free, unrestricted circulation of oil or grease directly through the rolling elements, making it the superior choice for oil-bath lubrication systems. Featuring standardized metric dimensions of an 85 mm bore, 150 mm outer diameter, and 28 mm width, this bearing delivers exceptionally smooth, high-speed rotation and robust load-bearing capabilities for internal machinery components.

The 6216 is a premium single-row open deep groove ball bearing crafted for heavy-duty rotary applications where continuous lubrication and minimal rotational resistance are paramount. Featuring an unsealed perimeter, this open-type configuration grants direct access to the internal ball complement and micro-raceways, making it an ideal fit for enclosed machinery operating with oil-bath or oil-mist lubrication setups. Manufactured to strict metric specifications—boasting an 80 mm bore, 140 mm outer diameter, and 26 mm width—the 6216 offers outstanding structural rigidity and reliable operational life under demanding mechanical loads.
