The WHITTET-HIGGINS PN 16 (equivalent to standard 22216 KMC3 specifications) is a high-performance, double-row spherical roller bearing engineered for the most demanding industrial environments. This unit features optimized internal geometry that provides superior capacity for both high radial and substantial axial loads, alongside exceptional self-aligning capabilities to compensate for shaft misalignment or housing deformation that frequently occurs in large machinery. Constructed from premium, high-purity bearing steel and utilizing a robust machined brass cage (M suffix equivalent), the PN 16 minimizes friction and heat generation under continuous operation, ensuring peak rotational accuracy and extended fatigue life in high-vibration applications such as crushers, vibratory screens, and gearboxes.
WHITTET-HIGGINS has equipped the PN 16 with proprietary sealing technology to maximize resistance against harsh contaminants like dust, moisture, and fine particulates, a critical factor for reducing premature failure in mining, pulp and paper, and heavy manufacturing sectors. Selecting the PN 16 minimizes operational downtime and total cost of ownership by offering unmatched reliability and longevity far exceeding typical standard counterparts. This bearing is specifically designed to maintain peak performance in demanding, high-impact environments where component failure is costly and unacceptable.
