The Nachi 22217EXW33K spherical roller bearing features a tapered bore with dimensions of 85mm inner diameter, 150mm outer diameter, and 36mm width. It is constructed with a durable steel cage and designed for high load capacity and misalignment tolerance, suitable for heavy-duty industrial applications. This bearing is heat stabilized for operation up to 200°C, ensuring minimal dimensional changes under thermal stress. The EX design incorporates larger diameter rollers for enhanced load ratings and reduced heat generation, supporting higher permissible rotational speeds. Made in Japan, it offers reliable performance with precise engineering for demanding environments.
