33212

The 33212 single row tapered roller bearing is a critical component for heavy-duty industrial applications requiring the management of simultaneous radial and axial loads. Featuring a precise 60mm bore, 110mm outside diameter, and a 38mm width, this metric-series bearing is engineered with a specialized internal geometry where the contact angles of the raceways and rollers converge at a common apex on the bearing axis. This design not only allows for high load-carrying capacity but also ensures minimal friction and heat generation during high-speed rotations. Typically constructed from premium chrome steel (SAE-52100), the 33212 model offers exceptional fatigue resistance and dimensional stability, making it a reliable choice for demanding environments like mining equipment, automotive transmissions, and agricultural machinery.

One of the standout features of the 33212 bearing is its separable design, which consists of the inner ring assembly (cone) and the outer ring (cup). This modularity simplifies the installation process and allows for easier maintenance inspections without the need to replace the entire unit. In most mechanical setups, these bearings are mounted in opposing pairs to handle thrust loads from either direction and to achieve the necessary preload for system rigidity. Whether you are looking to replace an OEM part in a truck wheel hub or integrating it into a new gearbox design, the 33212 provides a perfect balance of durability and precision. Its standardized ISO 355 dimensions ensure seamless interchangeability with top-tier brands like SKF, FAG, and Timken, offering engineers and procurement teams a versatile solution for reducing downtime.
