6215-2RS Deep Groove Ball Bearing | Heavy-Duty Double Rubber Sealed Performance | 75×130×25 mm

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.

Engineered for optimal balance between load capacity and high-speed efficiency, the 6222-ZZ is a premium single row deep groove ball bearing featuring a double-shielded architecture. Unlike open bearings that require continuous external lubrication, the "ZZ" configuration utilizes twin pressed-steel shields to lock in factory-filled grease while blocking the ingress of dust, debris, and moderate environmental contaminants. This maintenance-free design makes it an indispensable component for electric motors, industrial blowers, and automated systems where reliable, long-term operation without relubrication is essential.

Designed to deliver reliable performance in contaminant-rich environments, the 6222-2RS is a premium single row deep groove ball bearing featuring double-sided contact seals. Unlike open configurations, this fully enclosed architecture locks in high-quality grease for the entire lifespan of the bearing while aggressively blocking out moisture, dust, and abrasive particles. It is an indispensable component for exposed or semi-exposed industrial setups, ensuring zero-maintenance operation and consistent rotational stability where external lubrication is impractical.

Designed to deliver a perfect balance of rotational speed capability and robust load support, the 6222 is a highly versatile single row deep groove ball bearing featuring an open, seal-free architecture. Because it lacks external shields or seals, this unsealed bearing permits the unrestricted, continuous flow of lubricants directly into the ball and raceway assembly. This characteristic makes it an indispensable component for enclosed mechanical systems—such as high-output electric motors and oil-lubricated gear transmissions—where active oil circulation is crucial for dissipating heat and maintaining peak operational efficiency.

Designed to deliver unyielding performance in environments prone to heavy dust, moisture, and debris, the 6221-2RS is a premium single row deep groove ball bearing equipped with double contact rubber seals. Unlike open bearings that require constant external lubrication, this sealed architecture locks in high-quality grease for the lifespan of the component while blocking external contaminants. This makes it an indispensable asset for exposed mechanical systems, outdoor equipment, and industrial setups where maintenance access is difficult and continuous operational reliability is mandatory.
