The NTN 6219 ZZ C3 is a high-precision single-row deep groove ball bearing engineered for applications requiring robust performance and sustained reliability. Featuring precise dimensions of 95 mm bore (d), 130 mm outer diameter (D), and 18 mm width (B), this bearing incorporates double metal shields ("ZZ") securely pressed into the outer ring. These shields effectively retain the high-quality factory lubricant and provide exceptional protection against ingress from dust, dirt, and moderate moisture, ensuring minimal maintenance requirements and significantly extending the service life of the unit. The deep raceway grooves and close conformity between the balls and raceways allow this bearing to handle significant radial loads and moderate axial loads in both directions.
Specified with C3 radial internal clearance (greater than normal), the 6219 ZZ C3 is ideally suited for high-temperature operations, rapid acceleration scenarios, or applications involving tight press fits where thermal expansion or shaft deflection might otherwise cause premature binding and failure. As a product manufactured by NTN, a globally recognized leader in Japanese bearing technology, users benefit from superior material quality, optimized cage designs, and strict dimensional tolerances, resulting in consistent rotational accuracy and reduced vibration. This specific configuration is a standard, robust choice for heavy industrial gearboxes, large electric motors, HVAC systems, and high-duty pumping equipment where maximum uptime and operational efficiency are critical.
